Roger, Broadband systems do not need to be that bad. It isn't actually a "curse". In your system it probably comes from the antenna amplifiers. Unless you have something local, a better amplifier might be a cure. His system has no element amps. You have a product ending on a "5" because shortwave channels are involved. His systems, according to him anyway, involved an AM BCB station. It is impossible to generate a 5 internally in the antenna system unless shortwave is involved, or something on a channel ending in 5 kHz. It will be interesting to see if Wayne comments further, but if it is exclusively AM BCB it has to be a receiver image or a spurious in the AM transmitter. 73 Tom _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
