jim,
i just finished the CQ WW SSB and except for a very few stations the quality of
signals was good. i am using an Icom IC-7800.
i believe that if each of us take the time to contact the offending station and
explain, in a polite manner that they were "spattering". try to help them
correct the problem. the bands would clean up rapidly. every time that i do it
the problem is solved and the offending station is grateful. no one wants to be
rude to others. it's a friendly hobby after all.
complaining does no good.
73,
larry

what you mean by "self-police."> FURNISH THE COMPLAINT.Every time I tune my RX
to the SSB part of any active band, I hear splatter where the suppressed
sideband should be, and beyond the cutoff of the TX sideband filter on the
active sideband. And I see the distortion on a good spectrum display that I'm
certain is not being generated in the receiver. It is all too common for a SSB
station to be occupying 10 kHz of a band (and I'm not talking about stations
TRYING to transmit "hi-fi.)" And I typically observe this on many signals, not
just a few. It is not unusual for this splatter to be as strong as only 10-15
dB below the intentional signal. Casual ragchewers seem to be the worst
offenders, although some contesting lids are in that club.Why does this matter?
Because many of us want to work the weaker stations on either sid
e of that splattering rig. And because FCC Rules require that our transmitted
signal observe the minimum bandwidth required for the means of transmission.
And because using more than that bandwidth is selfish is piggish. It's the
equivalent of those obnoxious teenage (and older) drivers with super loud audio
systems driving down the road with their windows open, cranked up so loud that
you feel the vibration of the bass.In school, in WV, I learned that with rights
come responsibilities. Our licenses allow us to run high power to big antennas,
but they also require that our signals be clean.73, Jim
