The PTO provides 400-500 KHz of bandwidth, and I'm hoping that, properly designed, I can keep the diode turned on enough to actually hear stuff decently. What I'm trying to do is see how well I can make a minimal-parts-count receiver play. I'm also thinking about adding an RF amplifier to the front end, just to see how she plays. I do have schottky diodes to roll my own passive, doubly-balanced mixer, though I'd like to experiment a bit to see how well I can get the diode detector/mixer to work. It's also important to point out that I'm trying to use a 1N34A diode as a mixer. Well, this is kind of a somewhat unique application, so, first and foremost, let me provide a link to a schematic:
