So we got to building the board and testing it out. Everything is working as it should be. VFO is making signals where it should be, the Tx Rx switching works on command and the AF Amp is amping it up.
This is the output of the AF Preamp, its being slightly overdriven because i was to lazy to get the attenuators out and drop the signal level from the Function Gen down to the level you expect out of a mixer.
This is the output from the LM386 taken to the point of clipping. Looks reasonably clean and should make a nice racket when i put a speaker onto it.
