IC-905.

Something I have been working on for a while…

IC-905 SEND — Ethernet Relay Sequencer

IC-905 PoE Ethernet Tap monitoring control data from ethernet connected
IC-905 head unit outputs to a Pi5. Program on PI5 sequences relays based on
bands, multiple bands, or all with variable ms delays. I have 6 relays but
you can add more since they I2C connect to the Pi. Included is MQTT status
updates and I am working on expanding that so you can monitor via Network
or WIFI.
Bad band changes at TX cause sequencing to un-cycle old band and recycle
new band based on band selected.

Tap/Pi can be at Controller end or RF end (mast?).

Pi5 Click Shield
2 x Relay 5 Clicks

I plan to port to Arduino in the near term.
