Hello Sverre, 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. A (not the) source for the TDA3810 is "Segor Electronics" (www.segor.de) in Berlin/Germany. Type in "TDA3810" in the upper left corner and ma

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 l

The AOR TDF-370 is now out of production but had a binaural filter. The review in the September 2001 QST said that the CW Stereo function made a huge difference. Take a look at usascan.com/files/tdf370.html "Stereo" CW Reception: The built-in band pass filter has independent outputs for the l

I have done a couple of Binaural CW reception projects and found the results very appealing. Let me begin by sharing a few thoughts: 1. With binaural reception you normally would NOT use tight CW bandwidths as the object is to allow more audible information to be processed by our brain. I think t
