Used by many since, like so many good sayings. Churchill was good at it

In reply to a similar question at Dayton, Riley Hollingsworth
specifically addressed the legitimacy of hams using LSB on 20 meters and
above, and USB on 40 meters and below (with the possible exception of
160 meters which drew a laugh from the crowd). The convention
currently in use is

Hi,
Had to throw my 2 cents worth in. Personally I would welcome a shift to USB
on the lower bands, but I am not very optimistic it will happen. With DSP,
adding LSB to any radio is practically without cost (example K3: nil (ALT is
required by some CW ops) except for a few engineering hours) so

I had a PRC-74 for a good while and finally sold it as there was no LSB.
You're right about it not having LSB, Sandy. I've got an AN/PRC-74B
that I've never fired up, so I had forgotten that it should not have
been on my list of LSB-capable military sets. At least the 74B covers
20 meters (it
Try a CQ on the other sideband. Sure, most ops won't copy but those who
will might produce an interesting QSO.
If they have an Elecraft rig, it won't matter, since it covers both
sidebands.
And you might smoke out someone who has a rig that doesn't work on the other
sideband. Who knows, you
One time I heard a guy on 20m using LSB. I switched my rig over to
LSB, and we had a nice QSO. During the QSO, it turned out that he had
attended Ohio State University. Well, seeing as how I live in Ann
Arbor, MI (home of the University of MIchigan), I had a good chuckle
at his expense

IIRC the Hallicrafters rigs that I used 45 years ago
All my Drake rigs, T-4X(B,C) and TR-4C along with the R-4(ABC) work both
side bands on all bands. My Swan 240 doesn't, but it was a bare bones rig
when new. It covers 80 40 on lower and 20 on upper. They all use the 5 and
9 MC system.

You know, there is nothing, legally or technically, preventing anyone
from running USB on the bands below 10MHz if that is what they really
want to do. I am sure it will annoy someone tho'. I remember when I

Indeed, one of the first things I expect to see is pressure on Hams to adopt
USB as the standard
It's been a LONG time now, but I think I can at least
give the basic idea of how lower and upper SSB on
individual bands came about.
Most of the early SSB rigs ... all HB, of course ... were
built around a BC-458 (?) command set TX who's VFO
covered a range just above(?) 40M

Early filter rigs used 9 MHz crystal filters. With a 5.0 - 5.5 MHz VFO
(often from a surplus AN/ARC-5 or SCR-274N Command Set), you got 80 m
