====== 30m Phasing Rx ======

I recently found an old project that had been left in the junk box unfinished. It's a direct-conversion phasing receiver for 30m.

Inspired by my current binge-listen to the Soldesmoke Podcast [[https://www.soldersmoke.com/]] archives (I'm starting at the beginning and listening to them all.. currently I'm at around Episode 30) I thought I'd restart the project and build it into the planned-for 30m CW transceiver. There's a 5W PA strip that's recently been used in my [[qrss_tx| QRSS MEPT]] but I'll build a new PA for the MEPT and use the original one for it's original purpose.

I repaired a few broken wires and dry joints and the RX is working. I've checked that the phasing opposite-sideband rejection is working and given it a tweak to check that the adjustments are doing the right things. All looks good.

I'll document the circuit later FIXME

Here are some photos

There's a Makertube video of it receiving its first signals...
