Intrigued by the possibility of Binaural reception, where
audio filtering passes lo frequencies to the left ear
and higher ones to the right, causing the tuning of
a CW signal to move in front of your eyes, and musing
that headphones today are invariably stereo, and that
LM386 audio amps are as cheap as chips, that it should
be a feature of receivers to have two audio amps for the
stereo effect with the splitting filters before either of them,
and that those wishing speaker output might just as well
use the audio amps sold for computer use, and now that
the 100 miniature roller-operated microswitches have
arrived from China it is time to get on with the
"vapourware" 50 years RX project, if anything, just
to spite / spike one of M3OSN's guns?

We discussed this last year. I had some limited success using
Spectrumlab software but hit problems with tuning latency.

SM0VPO has a circuit for a hardware version here.
