Kenwood TK-790H - transmits, no audio

sfd745 · Sep 3, 2014

To all,

I have a Kenwood TK-790H (non-CDF) that will transmit but you cannot hear any audio from it. It will tag repeaters 50 miles away, but you cannot hear anything I say.

I have tried this with 3 different mics without any changes noted. I have tried transmitting on channels with PL, without PL, with DPL, without DPL, even simplex without PL. The radio keys up, you hear the squelch open on the other radio, but no audio from my radio.

I have ruled out the mic. The radio is putting out 110 watts with excellent SWR. I am stumped. Any help will be appreciated.

Thank you,

Higgy

You need to provide some more information. Like which control head is being used. Is this a remote trunk mounted radio or is the head right on the front of the radio?

I'm sorry, I didn't even think about all that. It's a 110 watt remote mount with full feature control head.

mine had the same problem I ended up having to go into "model information" and select voice scrambler as the option board and now it works
