CHANGE_LOG
For the Github commit log see here: github.com/jks-prv/Beagle_SDR_GPS/commits/master
v1.670,671 April 16, 2024
Fixed various problems with the new scheme of storing configuration information in JSON instead
of via URL encoding.
Due to community pushback, no longer enabling the new name/callsign entry panel by default.
If you want it then enable it via the checkbox on the admin control tab.
Admin console tab: added "clean logs" button you can use in case the updates are failing due
to lack of filesystem free space. If there is important info in the logs you want to keep
(e.g. WSPR/FT8 spots) please backup the log files before cleaning them.
Use the "disk free" button to see how much available filesystem space there is.
You need maybe 400 MB free to do an update.
v1.668,669 April 15, 2024
KiwiSDR Android app now working again.
In sig gen extension self-test mode always switch to CW mode so self-test carrier is
being accurately measured by the S-meter.
Admin "users" tab should now display IPv6 addresses and also load somewhat faster.
DX labels with embedded newlines ('\n') should now display correctly.
Shift/Ctrl/Alt-click of zoom in/out and page up/down icons work again in audio FFT mode
(bandwidth adjust and jump-to-nearest-label functions).
Don't enable the admin "require name/callsign" option by default.
v1.666,667 April 12, 2024
Extensions moved to main control panel so they can be used while another extension is in use:
Antenna Switch extension => RF tab
Waterfall extension => WF tab
Noise Blanker/Filter extensions => Audio tab
Those three tabs, RF/WF/Audio, now scroll vertically to accomodate the new content.
To avoid confusion all the previous methods of accessing those former extensions are still
available. So they continue to appear in the "extension" menu even though selecting them
now simply jumps to their respective control panel position.
Your existing bookmarks selecting an antenna will still work, e.g. kiwi:8073/?ext=ant,loop
even though there is now a simplified format: kiwi:8073/?ant=loop
Because mouse wheel (and trackpad emulation of that) will now cause scrolling of the
RF/WF/Audio panel content you must now hold shift while the cursor is positioned over a
slider to get the sliders to adjust using the mouse/trackpad (the prior behavior).
The antenna switch has been integrated into KiwiSDR codebase to make the above change possible.
My thanks to the author Kiwi Karvonen, OK1KK, for agreeing to this change.
The antenna switch frontend & backend scripts have not changed. But now live in the directory
/root/Beagle_SDR_GPS/pkgs/ant_switch instead of /root/extensions/ant_switch
If you had the extension installed and configured the settings will be carried over to the
Kiwi version. Backend selection and configuration has been added to the admin extensions page.
As changes are made to the admin config they are immediately reflected on the new antenna switch
area of the RF tab. No restarting is required anymore. The changes are significant enough that
there will likely be bugs in the new scheme.
The following improvements are based on suggestions made by the Kiwi community. Thanks everyone!
Waterfall tab (WFn) has a new entry called "Spec RF passband marker".
Similar to other SDR programs, when enabled this shows a transparent rectangle in the RF spectrum
that is the width of the passband. Color adjustment, including transparency, via a color picker.
Color is saved in browser storage. More marker improvements are planned, like being able to
adjust the passband width by dragging the edges of the marker.
Admin page:
New checkbox on control tab: "Require name/callsign entry when connecting".
Forces the user to enter a non-blank entry before a new connection will proceed.
Not shown again since the name/callsign is now in browser storage for this Kiwi.
RF attn slider on the admin config tab is now defined as the attenuation value preset
on server startup. When a connection is made from a user that has attenuator adjustment
permission, and has an attn value saved in browser storage, the storage value will be used.
The intent here is to provide a global default attenuation value when there are only users
connected who do not have attenuator adjust permission. Such as when the Kiwi owner/admin
knows a few dB is required to prevent significant ADC overload.
Admin password save:
On the admin security tab is a new switch "Save admin password in browser local storage?"
Note that browser storage is not the same as browser cookies in that local storage values
are not included in every web request as cookies are. Hence using local storage to save
the admin password is a better balance of security/convenience (but also note that cookies
are now gone as described below).
URL tab select:
You can now specify an admin tab to select in the URL, e.g. my_kiwi:8073/admin?dx
or my_kiwi:8073/admin?ext,ant to select the antenna switch submenu on the extensions tab.
The names can be a case-insensitive substring of the full tab/menu names.
So /admin?e,w to select the Extensions > WSPR submenu.
Map GPS resolution:
The webpage and public tabs had a button called "set from GPS" that would fill-in the
map/location fields with a lat/lon value computed by the GPS (if available).
The single button has been replaced with two: "lo res" and "hi res".
"lo res" works as before, giving only two significant digits of lat/lon.
A very rough location designed to protect your privacy.
The new "hi res" button gives the full 6-digits of resolution the GPS computes.
A warning is displayed when using this option telling you your precise location will be
revealed on map.kiwisdr.com and the [map] link at the top of the user page.
The webpage tab now allows customization of the user README/welcome panel (the panel with a
violet color) and also the password panel shown (if any) when a user connects.
If you make the customization entry empty the default text is restored.
There is additional error checking on the connect tab "Domain name" and "Specified IP" fields.
A domain name entry is looked up with DNS and an error displayed if the domain is not found.
An invalid IP address specification will also show an error message.
A new config tab checkbox controls if the geolocated city for a user connection will be shown.
New admin tab "Users":
Presents a list of all user connections since the server was last started.
Essentially a consolidation of the "ARRIVED" and "LEAVING" log messages.
A new entry appears when a user connects. And the "connected" time updates when a user leaves.
Users with the same name/callsign connecting from different IP addresses are shown in a
sublist, revealed by clicking an icon that will appear. Column sort options available.
One of the intended uses is to more conveniently spot new undesirable "bot" connections and
add them to the IP address blacklist.
A new webpage tab checkbox allows centering of the top bar splash photo.
The admin connection lockout period after restart (message: "Database update in progress")
has been eliminated. (thanks Christoph for recommending Linux "ipset")
New keyboard shortcut keys:
'$' toggles 1 Hz frequency readout. Also added a new entry in the right-click menu.
'%' toggles tuning lock (existing entry in the right-click menu).
'R' switches to RF tab.
Added AM wide mode. AM mode button now toggles AM => AMN => AMW => AM ...
AMW default passband values available on the admin config tab.
"Measure SNR now" button on admin control tab now shows result values next to the button.
User and admin status page SNR values are now updated promptly.
When the cursor hovers over the "SNR xx/yy dB" text in the title bar a popup describes the
frequency ranges xx and yy refer to.
Admin page > Extensions > FT8 has a new switch causing spots to be recorded to the syslog.
Same as what the WSPR extension has.
The AGC tab has a "defaults" button that returns all settings to nominal values.
TDoA extension: As you rollover markers, and they highlight yellow, they will now pop in front
of all other markers and be completely visible. Previously if they were obscured by another
marker you couldn't see all of their content.
rx.kiwisdr.com will show the product model (e.g. "KiwiSDR 1" or "KiwiSDR 2") instead of just
"KiwiSDR". But only for Kiwis running v1.666 or later.
All browser cookies have been moved to browser local storage. The difference is that local
storage is not transmitted with every web request like cookies are.
Cookies were originally used back in 2016 because local storage didn't exist back then.
Now it is widely supported by all modern browsers.
The cookie values were never used for anything on the Kiwi server side. Only for their
browser storage feature which persists across sessions. So their transmission with each
web request was very wasteful of network bandwidth (approximately 1 kB per web request).
Bugs fixed:
Owner/Admin email link no longer closes browser connection.
Fixed bug in DX label CSV import relating to start/stop schedule times.
Fixes bug where setting static IP with blank DNS entries disables Ethernet on Debian 11.
Some minor memory leaks were fixed.
v1.665 March 11, 2024
Fix EEPROMs with space in part number field.
v1.664 February 19, 2024
Fix to make photo file uploads on the admin webpage tab work again.
BBAI-64 Debian 11 backups:
If you've made any sd card backups using the admin backup tab, ON BBAI-64 ONLY,
then please do so again using this release.
There was a bug in the backup script that makes the backup unusable.
TDoA extension:
More fixes for waterfall preview mode colormap autoscaling.
Experimental optimizations to "spiderfy" of host and reference markers clusters.
1) When a host or ref cluster is expanded ("spiderfied") the other type of clusters are
temporarily removed. This eliminates the following annoyance. If the other type
of cluster is behind the expanded cluster (i.e. visible through the clear spaces of
the expanded cluster), and the mouse rolls over it, then the current cluster is closed
and the other type of cluster is expanded. This is almost always not what you want.
2) The last spiderfied cluster will now contract if the mouse moves far enough away from it.
Previously the only way for it to contract was to cause another cluster to spiderfy
(by rolling over it) or clicking in a clear area of the map (annoying).
Use my_kiwi:8073/adc_ov to report accumulated ADC overflow value as JSON e.g. {"adc_ov":1234}
Use my_kiwi:8073/adc_ov?reset to report value and reset it to zero.
Effects "adc_ov=" value reported by /status query.
The 'o' shortcut key now cycles between the control panel tabs: Off, User and Stat instead of
just Off and Stat.
Fix for timing bug where extensions specified in URL wouldn't always open.
v1.662,663 February 9, 2024
RF attenuator policy (KiwiSDR 2). Admin page control tab menu allows access by:
1) Everyone, 2) Local connections only, 3) Local connections or password only
These are the same choices as with the antenna switch. The password is the time limit
exemption password (admin control tab), specified in the URL by password= or pwd=,
not the user connection password (admin security tab).
Frequency undo/redo: When the frequency entry field is highlighted (almost all of the time)
type shift-return to undo/redo the last frequency change. Useful for old codgers like me who
keep misclicking or accidentally hitting the trackpad causing unwanted frequency changes.
TDoA extension:
The sampling station exclusion checkboxes are working again.
Waterfall adjusted so passband center is half way between extension and main control panels
if using a smaller sized display.
Sampling station waterfall preview mode bug fixes.
Fixed problem since v1.660 with map markers disappearing before you could click on them.
New URL parameter "refs:" that presets the "Reference station" checkboxes.
Use "refs:0" to uncheck all. Then "refs:[1-8]" cumulatively to add checkboxes from
the subcategories. For example "refs:0:2:3" to check milcom and radar.
Omit ":0" to make ":[1-8]" remove subcategories. I.e. "refs:2:3" selects
all except milcom and radar.
Added "save" buttons to admin text entry areas:
webpage tab > additional HTML/Javascript; network tab > local blacklist;
extensions tab > ALE_2G > admin menu; extensions tab > iframe > HTML/Javascript
v1.660,661 February 5, 2024
TDoA extension: Added fast waterfall preview of sampling stations. Shift-click on map host icons
or audio icon in host list. Waterfall (but not the audio) quickly switches to showing
what sampling station is receiving for 10 seconds (or until you click another),
then switches back to current Kiwi.
Admin network tab: Added option to control if blacklist is limited to Kiwi server port or not.
Useful for special cases e.g. when a local service such as DDNS must talk to a
hosting provider that is in a blacklisted IP range.
Changes to support KiwiSDR 2.
v1.659 January 25, 2024
Changes to support KiwiSDR 2.
v1.658 January 20, 2024
Added "clk_ext_freq=" to /status query for Rob.
Changes to support KiwiSDR 2.
v1.655,656,657 January 15, 2024
Fix S-meter ADC overflow indicator.
Added RF attenuator preset buttons in addition to slider.
v1.654 January 14, 2024
Debian 11+ backups now working.
TDoA working again after kiwirecorder bug fixed. TDoA extension now only shows sampling stations
running release v1.653 or later. Because pre and post CIC compensation filter Kiwis cannot be
mixed during a TDoA run.
Better user interface reaction when you're connected to the admin page using a proxy URL
and then change the proxy host name or user key. The admin page is automatically reloaded
using the new host name and/or user key.
v1.651,652,653 January 6, 2024
Possible fix for TDoA problem.
v1.650 January 4, 2024
Changed CIC compensation filter gain correction based on better measurements (+3 => +4.5 dB).
S-meter now shows 1/10 dB digit when value > -100 dBm.
Sig gen extension attenuation offset is now an independent value saved in browser storage.
v1.647,648,649 January 2, 2024
Finally fixed the long-standing problem with adjacent channel aliasing into the passband.
Fixed with Christoph's addition of FPGA CIC compensation filtering which you can read about here:
hcab14.blogspot.com/2024/01/kiwisdr-gets-cic-compensating-filters.html
See Kiwi forum for further discussion.
If non-zero RF attenuator value shown in S-meter as a reminder.
Updated HFDL system table to version 52.
v1.646 December 13, 2023
Fix DRM Journaline bug.
v1.644,645 December 12, 2023
Fix memory leak.
v1.641,642,643 December 6, 2023
DRM: Fix for audio high-frequency aliasing artifacts.
v1.640 December 2, 2023
Fixed problem with Galileo sats receiving newer subframe types incorrectly showing errors.
Changes to support KiwiSDR 2.
v1.639 November 26, 2023
New frequency memory menu user interface:
Auto or manual save mode.
Click-hold of memory icon does save in manual save mode.
Optional save/restore of demod mode.
Memory recall shortcut keys: ^1 ^2 ... ^9
Click-hold of VFO A/B icon does VFO A=B.
Help panel.
v1.637,638 November 22, 2023
Frequency memory:
Items are now stored in the memory only on demand instead of automatically while tuning.
The current frequency is stored in the frequency memory when:
1) The "store" entry at the top of the memory menu is clicked.
2) Or the freq memory icon (3 horizontal lines) is click-held for more than one second.
(it will turn green when the store occurs)
The "clear all" entry leaves only the current frequency in the memory.
FT8 extension:
Now decodes the DXpedition and Contest message formats.
Shows the "i3.n3" message format type under "msg" column.
Fixed some decoding bugs.
Waterfall tuning/zooming now resets the inactivity timer. For example if you're recording you
can reset the inactivity timer without having to change the frequency or mode.
Admin DX tab: Prevent corruption when frequency entered in not in sorted order.
v1.635,636 November 15, 2023
Support MMSSTV modes: MR73 MR90 MR115 MR140 MR175 MP73 MP115 MP140 MP175
Changes to support KiwiSDR 2.
v1.634 November 8, 2023
Fixed timing bug sometimes causing page reload failure when community dx labels selected.
Update RF attenuator slider when changed by other connections.
Note that admin-selectable adjustment policies are still not implemented yet.
v1.633 November 5, 2023
Adjusting waterfall cal on the admin config tab now has immediate effect, like S-meter cal has.
"set from GPS" buttons added to admin webpage tab and extensions FT8 subtab.
Changes to support KiwiSDR 2.
v1.631,632 October 27, 2023
S-meter URL query:
From a browser or curl use "my_kiwi:8073/s-meter/?(freq_in_kHz)"
e.g. "my_kiwi:8073/s-meter/?7020" returns the text "/s-meter: 7020.00 kHz -xxx dBm"
A 60 Hz CW passband is used to sample a presumed carrier on the specified frequency.
DX URL label filtering parameters added:
dx=(optional database specifier),ident:(ident),notes:(notes),case,grep
Populates the "DX label filter" panel with values as though you opened the panel
(e.g. with the "@" shortcut key). Example: my_kiwi:8073/f=15Mz0&dx=comm,id:HFDL
Where "comm" selects the community label database. "case" means the ident and notes values
are case sensitive. "grep" means the values are pattern-selecting regular expressions.
New shortcut alt-@ to quickly clear all DX label filtering values without opening the panel.
See the help button on the DX labels panel ("\" key) for more details.
Changes to support KiwiSDR 2.
Update Github README.md file with KiwiSDR 2 info.
Show KiwiSDR 2 PCB as default photo when user first connects.
v1.629,630 October 15, 2023
Allow clickable links in the DX label ident field. Example:
BEACON C&P #5 FSK <a href="https://www.hfunderground.com/wiki/Common_and_Precious_5"
target="_blank">hfunderground.com</a>
Results in the DX label: "BEACON C&P #5 FSK hfunderground.com" where the "hfunderground.com"
portion is an underlined clickable link. 'target="_blank"' makes the link open in a new tab.
The DX community database has two of these links at 4095 kHz for the Berlin C&P #5 beacon.
The hfunderground.com link goes to the beacon's wiki page. One label starts the CW decoder and
the other label starts the FSK decoder, for the two modes sent by this beacon.
Describe URL parameters in CW extension help.
Admin backup tab: Disabled on Debian 11 again because it's still not working quite right.
Admin network tab:
Debian 11: Static/DHCP setting change now works. Fix needed due to the Beagle guys migrating
from connman to systemd-networkd.
TDoA extension:
Top bar visibilities now correctly restored on extension close.
Changes to support KiwiSDR 2:
GPS clock startup hack.
Disable sig gen self-test menu item if ext clk enabled (both can't be used at the same time).
v1.627,628 October 5, 2023
Rework of admin backup tab:
Now works for Debian 11 and later. Debian 11 is currently used by the BBAI-64.
Progress bar now accurately shows sd card copy progress.
Should now correctly abort backup if admin page is reloaded while backup running.
Changes to support KiwiSDR 2.
Fixed bug where audio wouldn't un-mute after underlying masked area removed (thanks Rob).
The SNR-measure task ARRIVED/LEAVING messages are no longer logged.
v1.626 September 17, 2023
Error message and logging improvements to admin clone operation.
DX label uploads: improved realtime response.
In 14-channel mode (AI-64/AI/RPi only) GPS channels reduced from 12 to 10 to recover
needed FPGA space.
Updated Galileo and QZSS sat constellation tables.
v1.625 September 9, 2023
Must continue to support old EEPROM version value for KiwiSDR 1.
v1.624 September 6, 2023
Fixed bug in DX label CSV file importing.
v1.623 September 4, 2023
Added "RF" tab to user control panel. KiwiSDR 2 RF attenuator control is here.
In the future other functions will move here like the antenna switch.
Admin control tab: "daily restart" now a menu allowing restart or reboot (thanks Glenn, N6GN).
Other changes to support KiwiSDR 2.
v1.622 August 23, 2023
Instead of the full test message decode, ALE_2G extension will only show "[periodic self test]"
in the decode panel during the periodic self test which occurs every 4 hours.
Added fix for VPNs (e.g. Cloudflare WARP) that fragment the IP source address of related web sockets.
Added URL parameters and help panel to signal generator extension.
Changes to support KiwiSDR 2.
v1.621 July 21, 2023
DRM extension now works in Kiwi 3-channel, 20.25 kHz mode. This allows reception of
18 and 20 kHz wide DRM channels, e.g. India mediumwave (AM BCB).
Show platform (BBG/B, BBAI, BBAI-64, RPi) in user stats tab and admin status tab instead of
the previous fixed text of "BB" and "Beagle".
v1.620 July 17, 2023
New URL parameter "1hz" increasing frequency resolution to 1 Hz if Kiwi configured for 10 Hz.
Example: kiwi_name:8073/?1hz kiwi_name:8073/?...&1hz
Camping-mode panel now shows a message when:
The channel user has tuned to a masked frequency and the camper does not have masked
listening privileges i.e. "pwd=(time-limit-password)" not given.
The channel user disconnects.
v1.617,618,619 July 13, 2023
Loran-C extension: add entry for US west coast eLoran test GRI.
Misc fixes and improvements.
v1.615,616 July 8, 2023
Fixed problem with DX label edits causing audio glitching.
Fixed problem causing some Kiwis to not be seen on rx.kiwisdr.com list or
respond to admin network tab "check port open" button.
v1.612,613,614 July 5, 2023
Admin console improvements:
Can now paste from system clipboard into console (e.g. shell or text editor).
Mac: Use the usual command-v key.
Windows: Use the usual control-v, but type it twice in quick succession. This is because
control-v is used by the "nano" text editor for "page down". So there needs to be a
way for a control-v to get through that is not interpreted as a system paste. And this
is accomplished by typing control-v once, instead of twice, within a small time window.
The bottom line of the admin console tab displays a summary of these changes.
Many fixes to the ANSI command interpreter. This makes full screen programs like htop
(alias 'ht') and text editors work much better.
ALE-2G extension: Test function run every 4 hours as a workaround to prevent scanning lockup.
v1.611 July 1, 2023
Reduced occurrences of unnecessary config file updates.
Hopefully eliminated problems with corrupted configuration files by double checking json format
integrity immediately before file is written.
Added frequency offset to FT8 spots sent to pskreporter.info For example a Kiwi setup with a
6m downconverter will now send spots with the correct frequency.
For BBAI added Makefile dependency rule to automatically do "make install_kiwi_device_tree"
when required (same as BBAI-64 does now).
v1.610 Jun 28, 2023
Possible fix for observed memory corruption bug (thanks Paul, VK3KHZ).
v1.609 Jun 26, 2023
DX label system:
The stored dx label database (only if never modified by admin) has been updated to a snapshot
of the current community database.
Better error handling when there is corruption of the various dx label *.json files.
Error messages will appear in the admin DX tab and also the user DX labels panel.
Selecting a database menu entry on the DX labels panel now keeps the panel open.
Waterfall tuning: Type "#frequency" into the frequency entry box on the main control panel
to directly tune the waterfall center frequency (independently of the audio channel frequency).
For example if you're tuned to 7020 kHz listening to CW you could quickly tune the waterfall
to the 30m FT8 frequency by typing "#10136" Type "#" alone to return the waterfall to the
current audio channel frequency. The "k" and "M" suffixes apply, e.g. "#10M" for 10 MHz.
Previously the waterfall could only be tuned by mouse/touch gestures, shortcut keys and the
page up/down buttons.
Frequency entry field help: If the cursor is positioned over the frequency entry field,
and 'h' or '?' is typed, a help panel is shown with information about the optional passband
and waterfall tuning parameters. Typing 'h' or '?' with the cursor anywhere else shows the
standard help panel. Typing 'H' when no extension is open also opens shows this help.
v1.608 Jun 19, 2023
Antenna switch extension improvements:
Must install the latest extension from: github.com/jks-prv/KiwiSDR-antenna-switch-extension
Beagle GPIO backend now also works with BBAI and BBAI-64.
Beagle GPIO backend supports the full 10 channels, not just the default 8.
Selecting antenna via URL parameter when in password mode now works.
v1.605,606,607 Jun 15, 2023
Added variable sample time to TDoA extension (15, 30, 45, 60 seconds).
Right-click menu: new option "show cursor frequency". State is saved in a browser cookie.
Show selected label database on frequency scale.
Shift-click on "Spec RF/AF" button toggles in reverse (same effect as alt-s key).
New "dx" URL parameter "open" that shows DX labels panel.
i.e. "dx=2" vs "dx=2,open". See DX labels panel help.
DX community label database changes:
Adopted EiBi label type classification / color scheme.
Standardized on three letter country codes (except UK), two letter USA state codes.
DX labels panel shows type category names, colors and counts. Same as is done for EiBi.
Fixes:
Spec button toggle direction now correct.
Increased size of waterfall cursor frequency text.
v1.603,604 Jun 10, 2023
DX label popups no longer have modifier key explanations. Refer to DX label help button instead.
Extension help keyboard shortcut: When an extension is open (or the DX label panel) typing 'H'
will open the extension's help panel. The global help panel is still opened with 'h' or '?'
Clarified use of alt and control keys in global help panel and DX label help panel.
Bug fixes:
DX label panel "add" button now working.
Various fixes to labels with non-zero signal bandwidths.
Antenna disconnect detector now works properly for disconnect/reconnect transitions.
When displaying a large number of EiBi labels the audio should no longer glitch.
For BBAi-64 10 Mbps Ethernet mode is disabled due to the Ethernet interface hanging.
Fixed problem where 'x' shortcut key caused all subsequent shortcuts to stop functioning.
Fixed dist.admin.json recovery file.
Optimized size of DRM extension control panel.
v1.602 Jun 3, 2023
Only one admin connection at a time allowed:
To eliminate problems with corrupted configuration files multiple simultaneous admin
connections are no longer allowed. If you attempt to do so, and supply the admin password
if required, you will be given the opportunity to "kick" the other admin connection
(i.e. close it so that the current connection may now connect).
This "kick" feature is designed to solve the following problem: You have a Kiwi located at a
remote location, say, a two hours drive away. You unintentionally leave a computer at that
location connected as admin to the Kiwi. When you got home you would be unable to connect as
admin to the Kiwi without the "kick" feature (unless you could screen-share with the remote
computer and close its browser admin connection directly).
Why is my Kiwi restarting occasionally?
The admin status tab now shows a list of all possible reasons a nightly restart might occur.
And also describes where all the option settings are located to disable the restart cause.
DX label system -- many improvements and changes:
Default dx.json database update:
As you may know the default stored label database (dx.json file) dates from 2016.
It was really just everything we heard when the Kiwi first started working.
The hope was that it would serve as an example and Kiwi admins would customize it.
Well of course that didn't happen in many case. And lots of public Kiwis are now stuck
with an outdated and inappropriate set of labels.
So this release addresses that problem. The dx.json file is checked. And if it has never
been modified then a new, updated dx.json replaces it. We stress that if any change
whatsoever has been made to the dx.json file then this replacement will not occur
(i.e. no changes made by the owner/admin will be lost). The only exception is that
that label-related information contained in kiwi.json will be moved to the new file
dx_config.json as described below. Although the information itself will not be changed.
Community database:
It occurred to us that this idea could be extended as follows. A third database could be
added with this updated dx.json file as the starting point. It would be stored on
kiwisdr.com and periodically downloaded using the same mechanism as exist for updating
the IP blacklist. Changes to this database, called the "community" database, would be
made and discussed on the forum. We would consolidate the changes and maintain the file
as we do the IP blacklist.
So the community database appears as a third menu entry in the label edit panel of a
user connection. The shortcut keys also cycle through the database etc. And an admin can
set the default database that a new connection to a Kiwi will use via a menu entry at
the top of the admin DX tab. There is also a switch that determines if nightly
auto checking/downloading will occur. And a "Download now" button for manual control.
The current database is available for viewing:
Links on the kiwisdr.com webpage
kiwisdr.com/dx/dx_community.json
kiwisdr.com/dx/dx_community_config.json
Note that, just as with the ip blacklist, disabling auto downloading will prevent your
Kiwi from restarting during the nightly update window (if a new community database is
available).
Migrating label information out of kiwi.json:
In addition to the label information stored in dx.json additional information is stored
as part of the general kiwi.json config file. However this causes a problem when the
admin config "clone" function is used in the mode that only copies the label information
(and not the entire configuration). The label-related information cannot be easily
isolated from the rest of kiwi.json To solve this problem this release extracts the
label information out of kiwi.json and places it in a new file, dx_config.json, that
compliments dx.json These two files are then copied during a label-only clone operation.
A full admin clone also moves dx_config.json along with all the other config files.
CAUTION: Don't clone across the v1.{601,602} boundary. That is, Kiwis running v1.602
must not clone from Kiwis running v1.601 (or less). And vice versa. Let all your Kiwis
update to v1.602 (or greater) then resume cloning between them.
User interface changes:
Labels specifying an extension:
A black bar will now appear on the right side of the label. This gives user interface
consistency with mobile devices where there is no equivalent of the mouse-over
color change which occurs with the desktop interface.
Mobile device labels that specify an extension no longer always open the extension
when the label is touched. You must now touch-hold the label for longer than half a second.
The last database in use is saved in a browser cookie and restored when reconnecting.
Shortcut keys:
For EiBi you now use alt/ctrl-click (or shift-click) to not open the extension (if any).
This is now consistent with how the other databases work.
For desktop, mousing over the label shows all the valid key combinations in the popup.
The first time you click shift-\ (i.e. '|') the label panel appears as usual,
but for the current database rather than the following one.
Alt/ctrl '\' toggles the "filter by time/day-of-week" checkbox for the current database.
The right-click menu has entries to open all but the current label database
(now that we have more than two databases).
When changes are made in the label edit panel (from a user connection) the "modify" or
"add" buttons now highlight to remind you they need to be clicked to commit the changes.
EiBi database improvements:
Updated to the A32 version.
Service classification improvements (e.g. some entries now correctly classified as Aero).
The service counts on the control panel are no longer inflated by multiple schedule entries.
i.e. there are really only about 6000 EiBi entries, not 17000 as reported previously.
Time station passbands and extension settings optimized.
Fixed: Not all schedule entries were showing in the label popup for zoom levels 0-5.
Signal bandwidth:
A new label parameter "signal bandwidth" was added. When a label is clicked that has
this parameter specified a blue line appears below the label. The width of this line
represents the bandwidth of the signal. It is intended to be used for signals that are
much wider than the passband of the receiver (e.g. OTHR, CODAR, HFT, etc). The field
"sig bw" (kHz) now appears in the user label edit panel and admin DX tab.
The JSON/CSV export/import function handles the new field and will continue to accept
older files that don't contain the field. Further work may be needed to refine this idea
(suggested by Martin).
Admin DX tab, "Band bars" panel:
The freq/mode field on the right now allows an optional zoom to be specified.
Same format as "f=" URL parameter: freq[mode][zoom] e.g. 5154cwnz14
This was inspired by the Russian markers (single letter beacons), e.g. 5154 kHz,
where multiple labels are spaced 100 Hz apart and you really need to zoom in to see them.
Extension field frequency:
Many extensions interpret the first parameter of the label extension field (and also of
the URL parameters) as a frequency to match in the extension's preset menus.
So for example a label for frequency 4210 kHz (MSI safety, SITOR-B) could have an
extension field of "fsk,4210". But entering the same freq, 4210, in the extension field
is redundant and prone to error. So now an entry of "*" (e.g. "fsk,*") will simply pass
the label's frequency through to the extension. You can still specify a numeric frequency
for those few cases where the two frequencies are actually different.
(end DX label system improvements)
Antenna disconnect detector:
The SNR measurement process on the Kiwi now attempts to detect if the antenna is disconnected.
The consequences of this are:
1) A new field "ant_connected=1|0" will appear in a /status query (e.g. my_kiwi:8073/status)
2) rx.kiwisdr.com now shows the two SNR values (all:HF) in the listing for all Kiwis.
And a message plus red background will appear for any Kiwi with a disconnection.
There are criteria for deciding if there is a disconnect to hopefully prevent false-positives.
They are:
1) Only Kiwis operating at HF are considered (i.e. the admin config tab "freq scale offset"
field is zero. This is because other frequency ranges (especially V/UHF) can have
much more frequent periods of no signals compared to HF.
2) The "all" frequency SNR value (first one of the two displayed) is less than 4 dB.
3) There are no more than two signal peaks stronger than -100 dBm at HF (1.8 - 30/32 MHz).
This is needed because there were a number of public Kiwis observed that have greatly
attenuated reception (for whatever reason). There are signals there, but they are
very weak. The attenuation causes the SNR < 4 dB criteria above to be met.
FSK extension parameter aliases:
There are many parameters required to configure the fsk extension. Some aliases have now
been added to make things easier. Suppose you have a DX label for a SITOR-B signal with an
extension field of "fsk,*,s:170,b:100,4/7,i:0,CCIR476" Now you can simply say
"fsk,*,sitor-b" instead.
The available aliases are:
sitor-b s:170,b:100,4/7,i:0,CCIR476
wx s:450,b:50,5N1.5,i:1,ITA2
dsc s:170,b:100,7/3,i:1,DSC
selcall s:170,b:100,7/3,i:0,Selcall
ham s:170,b:45.45,5N1.5,i:0,ITA2
More can be added as needed. Use the extension help button to see the full/current list.
Spectrum peak hold buttons ('P1' & 'P2'):
If you hold shift while clicking the buttons toggle in reverse.
That is off->on->hold->off becomes off->hold->on->off
This means for example fewer clicks are required to go back-and-forth between on and hold.
Spectrum shortcut:
Typing alt/ctrl-s will toggle the spectrum selection in reverse:
That is off->RF->AF->off becomes off->AF->RF->off (shift-s already used for auto-scale)
Misc:
NBFM squelch fixed. Squelch should now close at a more reasonable slider setting.
Admin console column width now scales with window width.
Fixed problem with SPI device name for systems using latest BBAI-64 update.
v1.601 Apr 25, 2023
Admin page:
Debian version now shown on status tab.
Backup tab shows error message if Debian 11 (or higher) because backups not supported yet.
Currently this only effects BBAI-64. BBAI running Debian 9 and BBG/B Debian 10 work.
GPS: Fixed bug with Galileo solution accuracy introduced as a side-effect of Verilog
code cleanup (thanks Tom and Glenn).
v1.600 Apr 23, 2023
FT8/WSPR autorun:
For waterfall-limited, split configurations (e.g. rx8_wf2) allow waterfall channels to be
used initially (after rx3-rx7 have been filled) except for the case of preemption restart.
This restores the prior behavior allowing e.g. 7 of 8 channels to be initialized with
autorun processes.
Stop autorun processes during an sd card backup and resume afterwards.
v1.599 Apr 21, 2023
Autorun: Don't use waterfall channels on waterfall-limited, split configurations (e.g. rx8_wf2).
v1.598 Apr 19, 2023
/adc API: When a level of zero is specified (e.g. my_kiwi:8073/adc?level=0) the ADC overload
signal will be counted instead of the current "ADC value over level threshold" scheme.
This will give a precise count of ADC overload events compared to the "adc_ov=N" entry in
the /status API which is an averaged and quantized indicator.
FT8/WSPR admin page: Added "set all to regular use" button as a fast way to clear autorun menus.
Don't display unwanted top bar when extensions open.
v1.597 Apr 17, 2023
Autorun/preemption bug fix for TDoA extension.
v1.596 Apr 16, 2023
Autorun/preemption bug fixes.
v1.595 Apr 14, 2023
Autorun/preemption bug fixes.
v1.594 Apr 12, 2023
ADC level measurement: AJAX/JSON interface to help determine how much "headroom" is available in
the ADC. That is, how often the upper bits of the 14-bit ADC are getting set by strong signals.
Interface similar to how /snr works, i.e. my_kiwi:8073/adc?level=0x1800
Done this way so it doesn't require a channel connection, which would otherwise be very intrusive
given how often measurements will probably have to be made to properly characterize the headroom.
Note that this is fundamentally different from the current overload indicator on the S-meter
which is an averaged measurement of the full-scale overflow signal produced by the ADC itself.
Complete discussion on the forum.
The SNR measurement process will now run if a preemptible autorun channel is available (thanks Martin).
Admin page, control tab. New checkbox:
"Non-Kiwi connections (kiwirecorder, TDoA) can preempt autorun processes"
When an autorun process gets kicked the log will say e.g. "(PREEMPTED after 0:12:34)" instead of
"(LEAVING after 0:12:34)".
v1.593 Apr 11, 2023
Fixed problem where new user connections were incorrectly being redirected even though
preemptible autorun processes exist.
Fixed problem where camping a channel sometimes resulted in very low volume because the wrong
initial compression state was being used.
v1.592 Apr 10, 2023
Reverted change causing NBFM distortion (thanks Glenn).
FT8/WSPR autorun preemption: A new menu on the autorun configuration section allows you to
specify if an autorun process is preemptible. I.e. a new incoming user connection will
kick the autorun process off the channel and take its place. Every 10 seconds autorun processes
will attempt to fill empty channels. Kiwirecorder connections should not interrupt preemptible
autoruns. Only Kiwi user connections. (thanks Martin)
WSPR extension:
Control panel height now set to 90% the height of the waterfall (thanks Eric).
Spot upload debugging: On the admin > extensions > WSPR page, when "Log spot debug info?" is
"Yes" then an additional line in the log will show the actual upload response from wsprnet.org
e.g. WSPR UPLOAD: wsprnet.org said: "1 out of 1 spot(s) added"
Upload debugging only works for WSPR autorun currently.
S-meter extension: Defaults for all control panel values can be set on the
Admin > Extensions > S-meter page (thanks Eric).
kiwiclient/kiwirecorder: Added support for URL redirection. Requires most recent version of
kiwirecorder and kiwi server v1.592 or later to be used (thanks loststation).
Kick reason: The admin control tab has a new field "Reason if kicked" that will be displayed in
a panel when a user connection is kicked. Previously a kicked connection would just stop with
no explanation (thanks Rob who suggested this some time ago I believe).
Internal connections (e.g. autorun) behavior w.r.t. disabled/kicked connections:
An internal connection will ignore the disabling of user connections and ignore the
global kick button (both on admin control tab). However individual internal connections can
still be kicked via the button on the admin status page.
v1.591 Apr 3, 2023
FT8: Added autorun function. Works the same as WSPR autorun. See Admin > Extensions > FT8 page.
FT8/4 autorun channels display "NNN decoded", much like WSPR, where NNN is a count of pending
spots to be uploaded to pskreporter.info Pending, because uploads to pskreporter.info only
occur once every 5 minutes.
v1.589,590 Apr 1, 2023
Workaround added for the IQ extension residual phase rotation problem. Details on the forum:
forum.kiwisdr.com/index.php?p=/discussion/2852/unexpected-iq-phase-shift-in-gpsdo-kiwi/p1
Debian 8 is now deprecated. Existing Kiwis using Debian 8 and a recent Kiwi software version
will continue to receive auto-updates and don't really need to do anything.
But re-flashing from the factory v1.2 image (on the supplied sd card) or from the old v1.390
img.xz file no longer works as the Debian 8 repos from debian.org are now broken.
However, if you're running Debian 8 you can choose to upgrade to Debian 10.
Instructions are on the forum.
Spec AF:
Indented the maximum bandwidth edges and mark with red lines (thanks Paul).
Moved the de-emphasis filter before the FFT-based passband filter so the effect of
de-emphasis will now appear in the Spec AF display.
Spectrum peak hold:
In peak hold active mode a mousedown on P1 P2 for more than one second will clear the trace.
Added border to peak buttons P1 P1 with colors matching the yellow/magenta trace color.
Text colors similar to before: white=OFF green=ACTIVE orange=HOLD (was magenta)
Fixed problem where activating peak hold didn't always work in until the second try.
Admin console: Optimized ANSI color palette for increased contrast. For example a
"nano /etc/ssh/sshd_config" is readable now (thanks Rob). Fixed other ANSI-related bugs.
v1.587,588 Mar 13, 2023
FT8 extension:
Limit log output to 1024 lines (roughly 10 minutes of decodes). Prevents browser from
eventually going into meltdown.
Reverted SNR measurement change per request.
v1.585,586 Mar 12, 2023
The spectrum ("Spec") button on the main control panel now toggles between the existing
waterfall spectrum (renamed "Spec RF") and a new audio channel spectrum ("Spec AF").
Spec AF is identical to the spectrum function on the FFT extension (which has been removed).
This change allows the AF spectrum to be observed when other extensions (that don't use the
top display) are running. The sig gen in particular.
FT8 extension:
Set default SNR correction value to -22 dB.
Include decoder-computed SNR in spots uploaded to pskreporter.info
Added background color stripes to log messages for easier reading (thanks Martin).
Fixed bug causing incorrect reseting of admin page WSPR grid field while typing.
SNR reporting task takes twice as many measurements spread out over one minute.
v1.584 Mar 6, 2023
FT8 extension:
First URL parameter selects an entry in the freq menu, E.g. "my_kiwi:8073/?ext=ft8,10136"
Added clickable call/grid links to older, previously reported, spots.
Added "age" column. After a call/grid spot is uploaded to pskreporter.info the callsign is
cached and prevented from uploading again for 60 minutes. The age column shows this
cache timer. The age cache is cleared when FT8/FT4 mode is changed or the
frequency changed by more than 1 kHz, e.g. a band change or a change to a different
signal cluster (e.g. 10136 regular versus 10140 used for a particular DX operation).
Added link to pskreporter.info map page with the reporter callsign preset and defaults
of: all bands, signals, rcvd by, callsign, FT8, 24 hrs.
Added help button content.
v1.583 Mar 4, 2023
FT8 extension: Make spot callsign and grid clickable links like WSPR extension.
Fixed "Antenna switch extension is not configured" problem.
v1.581 Mar 3, 2023
FT8 extension initial release. See Kiwi forum for details.
v1.579 Mar 2, 2023
Revert spectrum peak hold colors.
Extension development/testing.
v1.578 Feb 12, 2023
Fixed bug setting dx label modes.
Improved high end response of NBFM de-emphasis filters.
Squelch value updated continuously while slider moved, not just on mouse-up.
New colors for spectrum peak hold traces and "slow dev" plot based on forum discussions.
v1.577 Feb 6, 2023
Audio response de-emphasis for AM/SSB and NBFM:
On the main control panel, audio tab, the "de-emp" menu to the right of the volume control
has been greatly improved. For AM/SSB modes the traditional 75 uS (N.Am) and 50 uS (EU)
filter profiles are available. For NBFM a 20 dB / decade (= 6 dB / octave) is available,
with or without ("+LF") attenuation below 400 Hz (e.g. to suppress PL tone etc).
The de-emp menu settings are stored and persistent across page reloads.
Comments welcome. These filters are now FIR-based and designed with Octave from a
frequency response profile. So they are easy to adjust.
A second spectrum peak hold is available. The "Pk" button on the WF tab has been replaced by
"P1" and "P2". Each click on Pk cycled between off/clear(wht) and hold(grn).
But P1 and P2 cycle between three states: off(wht) - on(grn) - hold(red).
This is so one can be in hold mode while the other is on. P1 is the yellow trace and P2 cyan.
The momentary zero icon of the left of the squelch slider has been changed to a toggle.
The default FAX passband has been lowered from 2200 Hz to 1200 Hz. It was observed that for weak
signals this slightly reduced the background noise in the image without lowering the overall
contrast, indicating that the extra passband width was just increasing the noise floor.
Comments welcome. You can type "/2200" or "/2k" in the frequency box to re-widen the passband.
v1.576 Feb 2, 2023
FM demodulator:
Added NNFM mode which has a 6 kHz passband useful for FM signals with +/- 2.5 kHz deviation.
Fixed "rough", "crackling" sound of demod. Needed a post-demod clipper.
WSPR extension:
Added test button. Test result spots are NOT uploaded to wsprnet.org
Added help panel.
Restore mode and passband on extension exit from: FAX, FFT, HFDL, IQ, SSTV and WSPR
By request, right-click menu shows both of these entries all the time:
"open DX label edit panel" and "edit last selected DX label"
Previously they appeared in a single menu slot under different conditions
which wasn't optimal for all use cases (Thanks W4ILM).
FAX frequency menu updates.
v1.574 Jan 9, 2023
DRM extension: preliminary slideshow support for testing.
IP blacklist: added 192.248.176.0/20 (constant/vultr/choopa) courtesy F4FPR. Thanks!
v1.573 Jan 1, 2023
DRM extension: preliminary Journaline support for testing.
v1.572 Dec 29, 2022
EiBi database fixes:
The label stepping function (alt-pan buttons or shift-alt/ctrl LR-arrow keys) with EiBi labels
was completely broken. The EiBi category selection and "filter by time/day-of-week" in the
"DX label edit" panel was not considered properly. In addition, entries in the
"DX label filter" panel are now properly considered.
Fix category misclassification of Shannon Aeradio and a few broadcast stations (e.g. WBCQ) in
the 5130 - 5150 kHz range.
v1.571 Dec 27, 2022
Admin page DX tab: CAUTION: If you have a "normal" Kiwi with HF DX labels only you don't need to
perform the conversion process described below. You don't need to do anything.
From this release forward new DX labels stored in the dx.json file will use
their true frequency instead of their normalized baseband freq (0 to 30/32 MHz). This will allow
proper label display when using a variable frequency downconverter (such as the freq extender
developed by Glenn, N6GN, www.sonic.net/~n6gn/BCReferenceBlock.png)
So for example if dx.json contains a combination of HF labels and airband labels (108-137 MHz)
then the airband labels won't be used until the Kiwi frequency offset is configured for
108 MHz (via either the admin interface or the "foff=108000" user page URL parameter).
However, this means there needs to be a conversion process for pre-v1.571 Kiwis with non-HF
labels in dx.json (e.g. those setup for airband or vhf/uhf ham bands). The label frequencies
must be adjusted from baseband to their true frequencies. This could be done (rather painfully)
one label at a time via the admin DX tab.
But in v1.571 a bulk mechanism for adding the freq offset to ALL the labels has been added.
It will appear at the top of the admin DX tab, but only if a non-zero frequency offset if set
(i.e. Kiwi is setup (presumably) for non-HF operation). When the "Add offset" button is pressed
a one-time addition of the current frequency offset is made to ALL labels in dx.json
The mechanism will then disappear and not be shown again since this is a one-time operation.
There is also a button saying: "Skip this and don't ask again". A backup copy of dx.json is
made for safety. Ask on the Kiwi forum if you get into trouble.
If you never removed the HF labels before beginning non-HF operation then DON'T perform the
above conversion. You don't want the HF labels to be shifted into your non-HF band.
Instead, with v1.571 or later, just begin adding labels with non-HF frequencies and they will
be stored with their true frequencies distinguishing them from the existing HF labels.
This change prevents the EiBi database labels from appearing when a frequency offset
is in effect. The change also makes the labels appear properly when only a part of the
