1. Check for good metal to metal contact where all the cabinet parts join,
particularly the internal screen. Make sure the sprogs aren't getting in
anywhere else, like the RS-232 cable.

2. As mentioned elsewhere by Eric, 5dB worse IMD in SSB. Considering the
difference between 100 and 120W won't be noticeable at the other end, it
isn't worth using it.
