[AMRadio] Zero beating

You are dead on of course, and we should do better. 

When it comes to preserving a frequency when on AM, and trying to keep SSB stations from zero beating us, we do pretty well just the way we are!! Go a step further and run a BC-375 or BC-223 on a windy day (MOPA design frequency shifts with antenna moving around) and we can really hold the frequencies from 3380 to 3890 when centered on 3885. ;-)

I will do better, thanks for asking..

Does no one zero beat the station they are talking to anymore?  Well,
I know a lot do, however since I've gotten back on the air after 5 or
6 years of absence, I've noticed this seems to be a real problem
nowadays.  I truly think that if more AM'ers would practice this, we
might hear less from the SSB stations, and conserve more BW in the
area so that other AM QSO's could be established.  There is one net in
particular on Tuesday nights I know of that has AM'ers all over the so
called AM window checking in.  In this case, the net controller should
instruct all stations to "zero beat" his signal, and do so several
times during the net.  During this net, I can't operate anywhere from
3880 to 3890.  The net occurs on 3885, or rather that's where everyone
should be.

Zero beating is just one way we could improve relations with SSB ops,
and ourselves...
