I have a nearby big radio station antenna about 2km away, maybe this is the cause.
In the olden days before "magical" op-amps and such I were involved with a project where we modulated a high frequency with the millivolt DC input, amplified and rectified it. All systems, save one worked beautifully and I were there trying to find out why. I were watching the signals and suddenly saw that I had signal on the scope when the probe was not touching. Problem" an Am transmitter at a frequency close to what we used had the antenna on top of the building :) Erik |
