CS800 Motorboating Like Sound

The fix for both motorboating (actually R.F. Feedback between antenna and the microphone) and external speaker.

You can also look inside the microphone and the radio to see if the fix was put in.

Need to put a really small capacitor (270 pF) across the microphone element.

Speaker Fix. Please open the cover of the unit to check if the part is physically there.

The speaker Mod is a capacitor in the speaker mike. To see if you have it, move the speaker around the antenna and see if you get motorboating when you transmit on the receiving radio. If you have no problems you either have the capacitor in or your radio is not as susceptible as other radios. We have only had a few people report the problem and hundreds of radios being used.
