I am trying to follow this circuit diagram:
Taken from (http://www.techlib.com/electronics/crystal.html)
Using two oscilloscopes I am watching the signal on the tuner circuit and the voltage created by the amplifier. First, before connecting the RF amp circuit, I adjust the tuner to ensure I am getting a good signal, then when I connect the positive terminal from the capacitor to the tuner circuit, the amplified signal does not appear to be modulating--I'm pretty sure it's not the proper signal.
My configuration is very slightly different:
I suspect that the RF amp circuit is affecting my tuning, but I don't know why and I don't know how to fix or compensate for this.
