What frequency are you on?
I'll need to look at a schematic to come up with much.

Hi Lowell,
Near the front end helical section of the reciever there are two crystals and a
trimmer near them Also, 3 coils that need alignment. There are the ones I am
talking about. I have a feeling that these are the ones that are not aligned
properly. The reciever is very sensitive-about. 12 for 12 DB Sinad quieting but
the audio, especially on a weak signal is distorted.
Thanks for any help.
