Up until recently, I could transmit SSB using my RR setup. Now, I can't transmit SSB; a different Control unit at a different location also can't transmit SSB. I've checked that the correct cables from the RR remote unit was plugged into the correct jack on the remote K3, and they were. I connected a different microphone to the remote K3, and it transmitted SSB no problem.
Is there any method of applying audio to the Remote unit on site, to test out the Remote unit? Any particular ports to check on the remote router? Any other guidance in what may have changed? As I said, it did work, but now it doesn't.
