[Hallicrafters] SSB generators: filter vs phasing

[Zengmeiste at aol.com]

OK, I'll bite. I'm gonna guess that the operational difference here
is How the sideband is obtained, straight hi-pass / lo-pass filtering
versus negative feedback to exclude one of the sidebands?
(I'm guessing, have not actually played with an xmtr. yet, and 
am still working on theory comprehension)

Thanks & 73, Terry B

ps
 did you notice how well QST mags from the 30's hold up?
they printed it on an incredibly high grade of paper stock. wow!
$125 for a Super SkyRider. Kewl! What was that, 4 months pay in 1938?
