    Default W4 A4 Control Head Minium Volume Mod

    Found that the minimum volume is about 1/2 on the Volume control on both A4 and W4 Rotary Control Heads..

    Changing R 8 to 1K, was 100 ohms, gives better overall control of the volume. This is the resistor in the bottom leg of the 2 K vol pot.

    Silly Question - did you check the "minimum volume settings" in the radio first? That would seem to apply here, possibly. Was that set at a minimum value already?
