The bottleneck is the audio circuits. That's why direct injection makes a big difference. I thought about switching between direct injection for AM and then running the radio's audio circuits for SSB... just switching the audio path thru a toggle. Dunno if I'm gonna do that yet. With the MRF477 final I have installed, my current obstacle is beefing up the power supply... then I'll think about dabbling around more with direct injection.
