The R7 doesn't use radials or a counterpoise. It is the electrical
equivalent of a 1/2 wave antenna on all bands. That was one of the reasons
that it was so popular.

Like the OP, I tend to agree that the problem is in the black box.

There were several articles published on how to restore the black box to
original specs. Anyone know of their location?
