>I have found loose screws to cause birdies on 10 meters. The birdies are
not a clean notes, but a broad rushing type sound that raises the S-meter an
s unit or two. I have measured about fifteen D,mp, and Mk5s, and find them
quite consistant. Most of these are at K9NS where there are two stations on
each band, stressing them to the limit. We see little variation radio to
radio. A DSP radio with no roofing filter like a Pro11 can not stand the
environment.
