There have been some interesting cases with short loaded antennas
in the BC band, the bandwidth has occasionally been so narrow that the AM
sidebands become attenuated! Not going to see that effect in the amateur
bands unless someone is running an
I believe that SSB was in use even before 1920. The Bell System used SSB in
FDM Mux
equipment (C-carrier, etc.,) in the 10's (1915 and later). This was
between 4.5 Khz
and 60Khz. As FDM technology improved the frequencies in use increased into
the megahertz
range. I have some modern FDM

Do you have the schematic of the sideband
filter you could send to me? I'd love to run it
through an analysis program to see the
frequency response.
