It sure sounds like RF in the shack. That one other person had the same
problem doesn't rule that out. It seems very unlikely that it would be a
software problem, with HRD choking on the number "40" in the band register.
I have had similar problems, and here are the steps that eliminated them.
Obviously, make sure you have the best ground you can, which you probably
have already done. If you're a long way from the ground point, use an
artificial ground, like the MFJ box. This fixed 90% of my problems. Run an
additional ground wire from the computer chassis to the station ground, and
use a ferrite core on the USB and audio connections to the computer, as well
as all connections to an outboard sound card.
My previous QTH was on the second floor, with a long wire in the attic for
an antenna. There was RF all over at first, but it was clean after taking
the above steps. Now, I have an outdoor doublet, but still do all the extra
