[Elecraft] Re: Binaural CW Reception

[Sverre Holm]

After having read the interesting thread about binaural CW and pseudo-stereo
I found these two descriptions of analog circuits that are fairly simple to
build. The most advanced one is by VE3VXO:
http://www.arsqrp.com/ars/pages/back_issues/2001_text/0501_text/street.html
. It has both phasing and loww/high-pass separation. A simpler one with only
filters is SM0VPS's circuit http://www.g3ycc.karoo.net/stereorx.htm

It would be nice though to find a TDA3810 pseudo-stereo IC and build a
circuit around it as Benny, OH9NB, suggested a couple of days ago.

Finally a digital alternative for a PC in MultiPSK, http://f6cte.free.fr/ .
Binaural CW is one of the free features in this program. I tried it but my
PC seems to be a bit on the slow side for this function, at least with the
default filter length.
