A static click in the radio also happened when setting the note and octave buttons and also when using the foot switch. > > There was no static in the radio while tuning a note. Some kind of interference from the SAT was affecting the radio. > > Sy Zabrocki Hey, this device has lots of stuff going on inside. It is after all, a computer. There is probably an oscillator to generate a A440 signal, perhaps some phase lock loops (old Hale SAT did) and who knows what else indide. I asked Paul for a schematic but they want to keep things secret. Anyway, put a radio next to your computer and listen. My ham radio is useless next to my computer. Mostly, it's the monitor that affects the equipment. -- Frank Cahill Associate Member Northern Va
