Before & After

  1. Beautiful. Here is a good tip. We all know the R1155 is no good on SSB except on manual gain control. This is simply fixed. The problem is AGC is applied to the mixer oscillator, which FMs the LO. Just take the AGC off the mixer and apply a fixed -3v to the grid using a zener diode. The performance on SSB then becomes PERFECT!
