Several years ago during a RTTY contest on 40 meters I noticed a weird
hash noise covering the entire band. It would come and go with a
timing like someone was calling CQ. Tuning around, I found a station
whose CQ was exactly in sync with the hash. I tried calling him to
advise of the problem but he totally ignored me. I am on the west
coast and he was on the east coast so you can imagine how much hash
power he was putting out.

Later I looked him up on QRZ.com and lo and behold there he was
bragging about his Class E amplifier and how wonderful it was!

I sent him an email but never heard back from him. I also never heard
that hash again. 

For what it's worth.
