This is spot on. If you can get a good counterpoise scheme worked out,
there's no need to move the shack downstairs. Your symptoms indicate that
the trouble is stemming from common mode currents on the outside of your
coax. Once these are cured, there may be no need to hang ferrites on the
connecting wires in the shack. It sounds as if you're on the right track,
but you can do more to choke off the common mode currents and divert them so
they won't travel on the coax.
