I've been holding off on making this video until I improved the stability. N6QW is vigilent! I only did this video after certifying that it meets the Juliano Stability Criteria. I had to dispense with the polyvaricon and go with an air variable. We will be talking about this on the SolderSmoke podcast next weekend. I hope to put on the blog a stage-by-stage discussion of how to build this receiver. The dial from HI8P and the knob from a SW receiver that Elisa gave me definitely add soul to this new machine.

All that hiss! Try a simple low pass audio filter. Eg 100nF or so across the volume control or even a capacitor across the audio output connection. The top right of the front panel is also crying out for an RF gain control!
Awesome Bill, and pretty stable, I've been working on similar designs: DC receivers with VXO's or LC VFO's and as suggested by Peter Parker a low pass filter does wonders on these things. the ones on SSD Page 82 are a bit more inolved but work relly well, much easier to tune without hearing all those high frequency audio components from all over the band. 72 and FB Bill, Dan -HK4DEI.
Very Nice indeed and you get the quality "passed" sticker for having a rig as stable as a Si5351. Wow -- with a bit more work you could turn that into a Superhetrodyne Receiver and then with a few more parts a full fledged SSB transceiver. How cool would that be?
