Remote Rig

My system has been working very nicely for several weeks now. The RemoteRig units are connected 100% of the time over my UHF link. My separate control system turns the remote equipment on, etc.
Today I have lost audio from the remote end. I have tried resetting both units with no difference. The CW sidetone still works fine, and I see something around 200kbs of data being sent - and this switches direction with ptt. (This seems rather more data than previously - it was about 160kbs.)
My first thought is that I have lost the audio input to the Radio unit. My second is that the audio at the Control end is VERY quiet - and I seem to remember some white noise even with no input when I was setting things up. But all the circuitry following the sidetone injection must be working properly.
I don't see that any of the settings on the units have changed. Probably it is my homebrew part somewhere that is broken, and I will take a trip to the tower tomorrow to check it out.
Any other suggestions please?

Roger, unfortunately I don't have any ideas about your problem but am interested in your UHF link and how you did it. I don't want to hijack your thread so if you like, you can respond to me via email at w4wt@arrl.net. I operate my remote station which is about 1.5 miles away via internet and have thought about microwave or UHF being a better deal financially.
Thanks,

Joe,
Look at some older threads, e.g.:

Mitch, thanks! The "bullet" looks very interesting indeed.

My problem was not related to RemoteRig. In order to interface my remote transceiver to the Radio unit, I had to build a small audio amplifier. The audio IC in this decided to die after a few weeks of use. I really have no idea why it should have died - the amplifier only has to drive a 50 Ohm load with a few mW.
