Binaural receivers can receive double sideband

Talented home brewer Stephen, VK2BLQ, mentioned that - unlike a direct conversion receiver - a binaural receiver can be used to listen to a double sideband transmitter. He sent some pictures and a sample recording.

I think this is promising in that it could be used to make a relatively simple transceiver comprising a double sideband transmitter and binaural receiver that could talk to another instance of the same design.

Here's Stephen's circuit notes:

 

Binaural receivers are useful for CW operators working with a busy part of the band as they spread signals out across the soundstage between your ears.
