Kenwood TK 790H Questions and Troubleshooting

[AK9R]

Probably not the cause of your audio problem, but on the end of the remote cable that plugs into the radio, there should be a flying lead with a ring terminal on it. That's a ground and it goes under a screw head that you should be able to see when you look through the "window" on the front cover on the main unit.

To add also, if the control head previously had an external speaker attached, it required the internal speaker to be disconnected. You would need to crack open the head to see if the speaker needs to be plugged back in.

Thanks for the info. Tonight after work I will open up the remote head and see if that wire is unplugged or loose, etc. I will advise what I find. Note, I do have other controllers and remote heads since I got these as a freebies since we moved to 800 MHz, so I can try another remote head.

Sorry for the late reply, but I did open up the remote head on the TK 790, looks like the positive and negative wire (two wires) going to the speaker on the remote head were in tact. No audio from receiving still. I did look at the 12 pin connector from the radio to the remote head, looked good. I also swapped another remote head in addition and the other remote head is doing the same thing, I’m scratching my head on this one. Any suggestions?
