Bill blames Dean KK4DAS, Farhan VU2ESE, and Wes W7ZOI for this recent bout of direct conversionism.
This all started when Farhan included a Permeability Tuned Oscillator in his Daylight Again rig. So Dean and I built PTOs. Then we built a super simple VFO that Farhan has in another DC receiver project. I attached a variable capacitor to this. Then of course I was on the way to a DC receiver. I used an AF amplifier I had built for another project. The receiver works great.
