    Picked up a MFJ-8621 data radio recently at a hamfest. It seems a bit 
weak on receive. The operation manual does not have a schematic. Google 
didn't come up with anything other that several folks have been looking for 
a schematic.

    Does such a schematic exist? This is an original MFJ-8621, not the more 
recent 8621A model.

    A PDF would be great.

Al, k9si
