I built this heterodyne VFO for a 30.4MHz LO for a 15M transceiver. This would not be quite the correct frequency range but the concept of a heterodyne oscillator is right out EMRFD. http://i732.photobucket.com/albums/ww328/Don_K5UOS/100_1420.jpg http://s732.photobucket.com/home/Don_K5UOS/tag/15%2520Meter%2520Transceiver I tried a similar idea for an oscillator for a 10M DSB transceiver. We have a local 10M sideband net @ 28.4MHz. The crystals are junk box crystals @ 10MHz and approx. 18.4MHz. I am also going to use KK7B's direct conversion receiver ideas. http://s732.photobucket.com/home/Don_K5UOS/tag/10%2520Meter%2520DSB%2520Proj ect This is a heterodyne oscillator project I tried. It worked but I never have used it in an actual rig. http://i732.photobucket.com/albums/ww328/Don_K5UOS/VFODualforSending.jpg A lot of the fun of home brewing is building analog oscillators. K5UOS
