Steve Berg <[EMAIL PROTECTED]> made an utterance to the drakelist gang
----------------------------------------------------------------------
I have never had a Drake receiver with a noise blanker, so I cannot
speak about their performance, but I have used the blankers in my Ten
Tec Argonaut II and the Omni V and find them to be very good. The one
in the Argo is very useful on pulse, solar, and auroral noise. I use it
as the tunable IF in my VHF system. It can overload on loud signals
that are near the frequency it is tuned to, but by backing off the RF
gain, this can be easily fixed. I wish someone made a blanker for the 2B.

Well, thanks to all for the many noise blanker comments.
Mods.dk has an article by KL7NA called "A New Noise Blanker for the
Drake R-4C" that describes the author's modification of an old TenTec NB
board to work in his R4C. In the article, he claims that it performed
far better than the Drake 4NB. The TenTec board is no longer available,
but he includes the schematic - it's less complex than the Drake unit
and would probably be pretty easy to scratch build.
I have no experience with either the Drake or TenTec blankers, so can't
comment on his results.
