[HBR] Regenerative communications receiver

[Brian Burns]

Hello All,

 

Since things are quiet on the HBR list, and Kees says that discussions of
other receivers are Ok, I thought that I would mention an interesting
regenerative that I've run across in Electric Radio.

Vernon Yeich, KB3RQE, wrote a couple of construction articles, first in ER
#227 and then in ER #241. He has followed those up with an article in ER
#301 entitled "A CW Receiver With a Double Tuned Regenerative Loop", with a
number of changes to the original design. All these back issues are
currently available from Electric Radio.

I certainly don't understand all I know about this radio, but it looks like
Vernon has attempted to incorporate some of the various refinements that
hams were coming up with at the end of the regenerative era, say the
beginning of WWII. He quotes some very impressive selectivity numbers, and
the design has some features not normally found in a regen.

Cheers,

Brian
