Hello ni9n! I've a question about your receiver: Do you use a kind of Swichting Mixer, sometimes called Tayloe Detector? Or ist it classic single or dual conversion? It would be interesting if you would post some more information about the bandpasses like which order they are. 73, Stephan

Two of the first lot of five are still available (I will be assembling them in the morning, so they don't show up as in stock yet) and I have just ordered parts for the second lot. Those should be ready to ship later in the week. To recap the LD-1's features (which are fully described at www.lazydogengineering.com/LD1home.htm ) it is a soundcard-based SDR like the Softrock-40 and similar SDR's, but with a dual-DDS local oscillator using two Analog Devices AD9834 DDS chips. It will cover the entire 530 kHz to 30+ MHz range. On the low end it will probably work below 530 kHz, but I haven't tested it there. It may go as high as 37 MHz, but I haven't tried that, eiter. It is USB controlled, either from Winrad or from its own stand-alone application. While I haven't done any formal performance measurements, it seems very comparable to my FT-817. Except, of course, being an SDR it runs rings around any conventional receiver when it comes to operator convenience and agility. I don't want to distract from the main topic of this discussion group, so I would like to encourage anyone who is interested in the LD-1, or DIY surface-mount projects, small-scale product developement, ham radio entrepreneurship, etc. to visit my blog at www.garage-shoppe.com.
