So i got this thing going.


Got the probe i ordered and i have been measuring D.C. A.C. and i even saw the AM signal on a battery powered receiver. How did i find it? Dont know. Just connected the groung wire to the groung reference in the receiver and then started poking around some resistors while getting different types of sinusoidal forms.


This is really cool stuff!

I was thinking of this thread while working on a solid state reciever last night.

I was watching the  ALC react and pinch down the gain, I watched the audio output looking for 'noise', I checked the low voltage and bias for nice clean DC, Checked and aligned the HFO's, looked at the BFO's output.

It is a pretty enlightning experience being able to visualize these things.
