Bliley Electric & Advertisements
July 1935 QST Article
two advertisements appeared in the July 1935 edition of QST. Bliley Electric is still in business here in Erie, Pennsylvania
as Bliley Technologies.
They make crystals and frequency sources. Gross Radio has been out of business for quite a while.
I included it mainly to illustrated how large radio transmitters used to be - these things were installed in
people's attics and basements back in the day. This particular model, the CB-100, is
a "100-Watt Radiophone & C.W. Transmitter completely housed in an entirely enclosed floor rack of ingenious
design." It operated in the 1.7, 3.5, 7 and 14 MHz bands. For comparison, iCOM makes a
power amplifier today covering those bands that measures roughly 6"(H) × 3"(W) × 9"(D) and weighs 55 lbs.
