       and reduce the noise floor.
       A receiver alignment is not necessary, but could be done to
       ensure proper alignment.
       Change D34 & D35 to NTE583 Schottky Diodes.
       Change Q18 to a 2SC2999 (Keep for SSB Upgrade)

       NB Upgrade This will make your Noise Blanker more effective.
