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.
Thanks,
