So the dead bug version of the balanced modulator is done. The prototype was unstable but gave me almost 40 dB of suppression. THIS version is rock stable, but gives me only 26 dB of suppression. DAMN! I wanted a challenge, I got one.

Based on the fact that the trimmer cap is almost useless, I suspect stray capacitance is the culprit. I won't give up. Some guys in the radio club said "No one can build an SSB transmitter at home" - I took that as a challenge, one I will not walk away from. I'ts going down to 14F tonight here in Texas, what ELSE do I have to do this weekend?
