Was talking on cb and power supply went to beeping and will not quit. Unplugged it and plugged it back in and still does it. I have a Galaxy DX98VHP hooked up to it in a scale house. Took cb off and it still beeps.

try an external speaker........it might be a bad speaker in the radio

there is more then setting the power on low or high. there are knobs to turn dials to set and other adjustments. Get a manual and check it out or better then that get a tech to do it.

well I'm sorry to say with todays new trucks, I found in a Volvo660 only 20 maybe 30mi with 100w. No metal on trucks any more. I drove a 1982 359 pete for my first truck 100w. I could talk to anybody i could hear. went from that truck to an 89 fld120 lost radio performance. then to the 660 which seem def. I could hear people but it was hard to be heard. even with an amp.

thats ssb for you. How far does it drift?

Bad grounds, high swr when under load. Quality of coax.

if you modify a export radio YOU MAY NOT TRANSMIT on it. It is ok to listen. just remove the board or 8volts to the final rf transistors to keep it legal. then just change the pll logic to open to the other bands.

yeah your mic gain is way too high. You can either turn off talk back if you can, or turn the gain down. Depending on how loud the talk back is, your audio may suffer. If that is the case, you will not be able to run that mic. Get an RK-56 or a Skythumper mic. They are noise canceling. You will get no squeal with that mic, and it will sound awesome.

If you really want a roger beep, take it to a tech and them install one.

the talkback is too loud. there is no way to adjust the talkback volume on this radio. Talkback is really just so you can check how your audio sounds and your echo. Once it set, there is really no need to have it on.

Turning down the gain on your mic will stop the squeal.

the squeal is cause by feed back from audio from the talk back being heard from the mic.
