Re: #ubitx-help Strong Audio Tones in and outside audio receive passband #ubitx-help

Jerry, I am not sure which is the problem, but I can't tell now that I destroyed the Arduino.

The key pointer was when I connected a 1nF capacitor to one side of the Arduino crystal to ground, effectively stopping the clock of the cpu, the tones within the passband would disappear (as well as any control of course).

Cheers, John
