If that's what you restrict the conversation to, sure - even I'd get
bored, and I'm easily amused. Folks I talk with discuss the rigs they
are running, restoring, or building,along with effective antennae,
other projects, history, life, etc etc. Listening in to the
intercom-type exchanges on SSB causes me to doze if I don't change the
dial. Seldom any radio content beyond the latest linear amp, and
really not unlike the memories I have of CB where folks used it merely
for convenience, not enjoyment. I don't know about you, but I got
interested in radio for....radio?

'Most' in the circles you prefer, Bob. To deny the explosion of
popularity in AM in recent years means you're either not paying
attention or choose to believe otherwise.

Why not start another conversation on a *different* frequency? This is
what I refer to with the tendency by some to 'clump' onto one
frequency. With all the AM activity and phone spectrum available,
there is no excuse to have those massive roundtables, muchless to stay
in one if it bores or otherwise annoys you. Take the lead, don't wait
to be led.

Uh.....maybe you missed this Bob, but AM was being left off SSB/CW
rigs some years ago including the much-vaunted Collins S-Line, KWM-2,
even the first 'super rig' that all the big Yaecomwood riceboxes are
modeled after: the KWM-380 (although it at least provided receive
capabilities). As AM stabilized and began again to grow years ago,
manufacturers began including the mode on their equipment again. They
obviously didn't do this because it was cheaper, or unfavorable.

Yes, well....it's not unlike moving to a gated neighborhood or densely
populated development and trying to build an airstrip. Chances are
good to excellent that someone will notice and object. The better
choice would be to live in an area where neighbors aren't close enough
to be a problem, and real radio can be enjoyed. Maybe not as
convenient as living in the city or even outskirts, but necessary if
you want to run big radios and have something beyond the G5RV or small
tribander in the air. It's certainly not for everyone.

You probably still cause interference, especially when you run that
big SSB signal you eluded to previously. SSB is just a lot harder to
identify and trace than the natural human voice.

If nothing else Bob, you've at least made it clear why you think those
AMers better stay in a little sliver of the bands and tolerate
intentional interference from SSB stations. I'm just thankful that
everyone else who has responded to this thread sees AM as a standard
phone mode entitled to the same treatment as SSB. Seems to go against
that 'minority' view you hold of AM. Okay, so it's an AM reflector...

73, and thanks for the banter - hope to work you on AM once I get down
there. I'll expect a strapping signal from you, too. (o:
