Oh yes, I forgot to mention:
VSB versus SSB versus "real" AM:
VSB is NOT the same as SSB with carrier. VSB
operates as DSB at lower modulating frequencies.
As you raise the modulating frequency the signal
becomes SSB.
The reason VSB can sound better than SSB with
carrier is that most of th

Every single statement you made is true. SSB
with one sideband sucks at high percentages
of modulation.

I agree, modern radios (Kenwood etc) generate DSB with carrier that can be
set to the proper level.
All TV Stations, up to going digital, used VSB WITH carrier but only for the
video. The voice was 25 KHz FM Dev.

Yes you're right - almost all SSB rigs from the 60s & 70s basically were one
sideband and a ca
Although not a true AM mode as the seasoned amateurs might define it, one
sideband with carrier inserted, can work reasonably well, and does
especially well in crowded band conditions. Actually Don, the last time
we worked on 75 M, one early morning last Fall (or maybe late Summer), I

First, this is my first post to this interesting group and I
hope you take what I have to say constructively.
This business of SSB on AM, etc., is of interest to me
on a technical basis.
But let's do a computer simulation of this thing. To
this end I have written a computer program

The last radio that I saw that used a carrier with ONE sideband for AM

Swan did the same thing. There was a 'carrier null

A number of the early phasing type transmitters/exciters and SSB adapters
allowed you to operate on "AM" with just one sideband. So, only operating
DSB AM would really be an issue.
