IIRC - About 25kHz on both Sides ? - Right or Wrong ?

i want to know ~ RHF


The ones I listened to were pretty clean. (RCI and RNZI). They
were just in their 10 kHz wide block. (Or as well as I could tell
with my 2.? kHz SSB filter).

Receivers with crummy filter skirts will have a problem because the
power across the signal seems constant, unlike an AM signal which
won't have that much power out at the extremes edge of its sidebands.

What would happen if the likes of Radio Cairo or some of the sloppier
Christians got a hold of it wouldn't be pretty, though. Gene Scott's
operation could crap up an entire band with just AM, because they just
didn't seem to know what they were doing. (Splatter city on 9725 kHz).
