Check out the softrock40 and the dds_controller Yahoo groups. Both have Quad Sampling Detectors using the Tayloe Detector. The softrock40 and later variants are the simpler and are crystal controlled. Kits are available. The dds_controller group is writing software for the 995x board among others. The 995x board is a USB controlled DDS RF generator and a QSD circuit that works at least from 160 meters through 6 meters(the RF generator works to 160 MHz or higher). The PCB only is available. You must get your own parts from DigiKey and mini-circuits lab. Also, the 995x has very fine(.0196") pitch IC's to solder. The softrocks use nothing smaller than a SOIC(.05" spacing).
