80m SSB Receiver - Weaver method

Update:

I am living through a record breaking heatwave (6 days above 38c) so it's strictly indoor activity at present. I did waste a few hours uploading the gerbers for the boards shown below to a PCBA bureau. Turns out that with another day or so on my part I could consolidate both boards and by adjusting the components get 5 populated boards delivered for around $20 each (say USD14). All that would be left is a few through hole components. The op-amps were changed to the surface mount version. Tempting? Or is it the heat getting to me?

This is part of a longer term project to build a complete transceiver. Initial testing of the receiver boards shows demodulation and opposite sideband rejection are taking place. I look forward to mounting these boards on a chassis together with the audio amplifier / AGC / squelch board and synthesizer board for further testing and evaluation.

Using a D2E-S-DC12V to Switch RF at 6M

 

Initial tests are encouraging. Insertion loss less than 0.3dB and both isolation and return loss around 35dB.

Time now to put it on the 6m radio and see how it copes with 50W of FM.
