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. 73 Sverre LA3ZA http://www.qslnet.de/la3za/ _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
