Waveforms for SR radio (for my self, only).
3.1.A SR Receiver, waveforms, Test point C.
A. Waveforms at Tp.A.
B. Waveforms at Tp.B.
C. Waveforms at Tp.C (you are here).
The following wave forms show what happens at test point "C".
This is the audio signal that is output from the amplifier (Q2,Q3). Actually, this is noise, but scope shows its amplitude at 1V/dev.
The rest is the same audio output, slightly different looks.
*** And if you have "something" to add or have questions, then my address below.
