I wonder how many of you realise that when you are operating Single Sideband
Suppressed Carrier you are on Amplitude Modulation ??

Yet AM is still allowed.


Yes, it certainly is. But for how long?

Good question, but it has been some 40+ years since SSB
pretty much took over as the HF mode...and there's still no
call for any ban of AM.

Riley Hollingsworth told a Richmond, Virginia hamfest last spring
(speaking of "enhanced SSB") that deliberately operating a wideband
mode in a crowded spectrum is "shortsighted and rude," may be ignoring
the "minimum bandwidth necessary" rule. Now if 4.5KHz-wide signals are
shortsighted and rude, then it logically follows that 6KHz-wide AM
signals containing the same information are even more shortsighted and
rude.

He also hinted that continued complaints "WILL (my emphasis) lead to
pressure on the FCC to revise the Amateur Service rules." Would you
expect DSB AM to survive such revision?

Not if such DSB AM was in any way a significant percentage
of use on the air. That sure doesn't seem to be the case at
all, however.
