Hi, Gang

Pete Millett has recently moved to a new hosting site, and expanded
his collection of old electronics textbooks available for download.
The new site is he
http://www.tubebooks.org/technical_books_online.htm

One very good book is the GE Sideband Handbook,
a compilation of all the SSB info appearing
in the GE "Ham News". Included is the GE "SSB, Jr."
the forerunner of the Central Electronics 10A.

I'll grab it, but does it have much on DSB? GE seemed to be
the proponent for DSBsc (versus Collins and SSB), and Webb who
wrote an article about DSBsc and then a construction article about
making a synchronous detector (about 1957 in "CQ"), I thought he
worked for GE. They were talking about full blown DSB with proper
detectors, to do away with the carrier but make use of the benefits
of two sidebands. DSB is covered in the other SSB books, but there it's
an intermediate step, simpler to build than an SSB transmitter but simpler
and better than an AM transmitter, but one was expected to receive it
with an SSB receiver which turned the DSB signal into an SSB signal before
the product detector.

Pete's site can be rather slow, so I moved a copy of the GE SSB Manual
to Rapidshare, since it is a large file (151MB):
