Nothing anywhere says you can not operate AM mode anywhere in the
phone band your license will allow you to operate.

There is no "Window", just a calling freq of 3.885.  Same on 10m - the AM
calling frequency is 29.00.  Just like 146.52, and 52.525Mc, those simplex
"calling frequencies" are just that, and as soon as you establish contact,
move off of the calling frequency (where*EVER* you can find a clear spot)
and move your conversation (phone)/QSO (CW) there.  (CW is allowed
everywhere still, right? ;-))

So, if I call CQ on 3.885, and there's an AM conversation on 3.880 and another
on 3.890, I'm gonna go hunt up/down and find a hole somewhere else that
this station and I can mutually work, together.  I, being the Extra, would ask
the other party where he'd be comfortable at.  3.870?  3.875?  3.753.45?
 I -have-
a VFO, so it don't matter.

Speaking of which... Not Having a VFO is no excuse, either.  If you've a
crystal, you can feed a vfo signal in that same socket.  Even if it's only a
level output from a ricebox, you can feed a small amount of RF in there, to
make that old rig frequency agile.

I conlude that the general concession is that a lot of the "local discussions"
75m is, well.. let's just say it's not fit for mixed company.  Not that I'm a
but I also get that more gentlemen operate AM than there are Gentlemen on
most SSB frequencies.  Being polite Gentlemen, and not being diliberate, why
-not- fire up AM QSO's, starting at 3.753 (if the frequency is clear) and having
a pair of guys every 6kc (when possible) and fill the whole cotton pickin' band
with AM.  THEN, when the Sidebanders whine and complain about ALL the
AM, we -could- say "Fine.  We'll confine ourselves to these 30kc *if* you
keep your SSB QSO's off of say between 3.860 to 3.890."  But, then that puts
us back in a "window" or a box, if you will.  No.. upon further reflection, I
believe that operating an AM rig anywhere you're allowed phone operation
is what the answer is.  Being limited to 3.870/75/80/85 and 90 on 75m is -not-
conducive to further growth of our little spectrum of the hobby.

If we want to 'raise the level of politeness' on 75m, then let's get AM'ers on
the band, starting from 3.753, and getting a qso going every 6kc up the band.

Getting everyone on, at the same time, is a logistical nightmare, but a -lot- of
people have a -lot- more free-time during the holiday season.

Any suggestions as to when this should happen?
