Thanks to those who have placed orders for or expressed interest in the LD-1 software defined receiver, which I am now shipping. 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.
