|[AMRadio] 7160 tonight: Suggestion|

I see this all over, and its just poor operating practice.
Some guys will be 2 or even 3 KHz low, someone else might be 1 or 2 KHz
high, some guys are overmodulating and/or have no restrictions on the high
end of the audio, and the qso is 10 KHz wide, which is rude.
Not so important on an empty band, but still poor operating practice all
I know its hard to keep some rigs on frequency, you need to zero beat often.
When I had the drake R4C, sometimes I only heard one guy in a qso, the other
guy was out of the passband!

When has that ever bothered you before, Don? To borrow your own words
on such matters, 'strap and ignore', 'turn up the wick' etc. I'd agree
with you if folks were scattered out over 4-5 kcs or more, but 1-2
seems m ore related to sync detectors not locking up than to offending
any SSB ops. After all, it's been one of the ways to discourage
anti-AM SSB types from crowding in close to a QSO in progress.

Excellent point, and all the more reason to use whatever frequency is
open. Hopefully as activity grows, people will fan out and use more
than one frequency to prevent the 3885 effect from taking place, with
20+ people in a roundtable or another AM QSO 4-5 kcs away.

More space is always a good thing, but it might be hard to justify in
the face of current activity levels(not that we should have to justify
it, but it is the FCC). Think of the nights recently when you, 'HUZ
and others have listened over the 40m band and found virtually no
activity as your reports and charts indicated. With the bandwarming
party on 80m, we saw an initial influx of activity both AM and SSB
after the phone expansion, but very little was actually new users
looking for space. More often than not, it was some group or net
moving to a clearer area, which in turn opens up more space or at
least, helps alleviate crowding by the lemmings in certain congested
areas of the bands.
80m is finally showing several groups of regular AM activity below
3750 daily. It'll be interesting to see how activity on 40 plays out
with the BC dwindling in the lower portion. Considering the overall
lack of activity across the band, I doubt we need to be too concerned
about anyone beyond the usual rabid anti-AM types giving us grief.
Just hearing AM activity is bound to attract some nitwits, even if
everyone is dead on frequency. Of course, good operating procedures
should always be followed, regardless. :D
Back out to get more done on the station...
