@hangar_101 said in Comm Power Circuits in Black Square Products:
if I switch to COM3 RECEIVE ON / COM3 MIC ON and manually turn COM1 RECEIVE OFF, after a few seconds the SI app turns COM1 RECEIVE back on again.
Now that I haven't seen.
Although in the process of trying to replicate it, I found something interesting. if you turn both comm1 and comm2 receive off in the Starship, SI will show as active (green) only whichever radio is selected as the transmitter. So setting transmit to comm2 causes SI to show COM1's frequency in grey.
Looking at COM RECEIVE:1 and COM RECEIVE:2 in Simvar Watcher, sure enough, they're set to 1 if that radio is set to transmit, regardless of whether it's set to receive. So my understanding about COM RECEIVE:1 and COM RECEIVE:2 being different was incorrect; it's the transmit selection that's causing it.
But there doesn't seem to be an MSFS function to set transmit to com3?
EDIT: Alright I see now, if you send the control PILOT_TRANSMITTER_SET with a value of 2 (0 = com1, 1 = com2, so 2 is presumably com3) then SI briefly shows both com1 and com2 freqs greyed out (which made me happy for a few seconds) before automatically switching com1 receive on (though not com1 transmit). What in the world?
