This project is intended to operate a remote antenna switch.
It supports (up to) a 2-radio, 8-antenna switch, however, my target is an Array Solutions "SixPak" which is a 2-radio, 6-antenna remote switch.
Why IOT? That's really about WiFi. The board uses WiFi to connect to your network, which means that only power needs to be protected from Zeus, not 14 +/- wires.
I have built matching "band-decoders" to interface with my Elecraft HF radios.
The band decoders detect a band change on the radio and send a API request to
the switch control board to request an antenna for that band. If no antenna
is available, the band decoder will activate the K3s' "TX INHIBIT" lead and
prevent the radio from transmitting into the wrong antenna or no antenna.
The Band Selector (radio interface) is here — This is the other component for this project, you will need two — one for each radio.
- Bill of Materials
- The approximate cost to buy these parts is about $106.
(note that the hardware supports a 2x8 switch, too.)
