[GreenKeys] period HF receivers

[Richard Knoppow]

    I have a kit for my R-388 but have never had time to install it. 
They have an excellent reputation.  My receiver has the PD and AVC mods 
that were earlier. The PD works OK but  the AVC is awful.
    I want to ask the fellow who designed the Treetop circuit about some 
sort of noise limiter that would be suitable for use with it.
