Experiments with a PA2OHH phasing method direct conversion receiver

Imagine a very simple and cheap direct conversion receiver that greatly attenuates the opposite sideband with no crystal filters, almost all discrete parts and only the simplest of RF and audio phase shift networks. Here's one for 7 MHz I knocked up on some modified QRSS designs from PA2OHH.

If you want to follow my results start by building either of the PA2OHH QRSS receiver circuits presented here:

Great video and explanation. I'm still trying to wrap my head around phasing SSB exciters.

Hello mate. I bought one of the ic202 ssb radio recently like you have. I didnt try it yet but look like it might work.

This looks very useful for decoding DSB transmissions. Cheers!

PA2OHH and his call-sign-name-sack PY2OHH both have websites and are good QRP HOMEBREWS.

neat. And an example of 'ugly' construction too!

Is this rx good enough for a tx? Seems so, seems like a winner, I like it!!!
