FUNcube SDR Dongle in the House

We have just taken delivery of a FUNcube SDR dongle. If you are not familiar with the FUNcube dongle it is a SDR radio that connects to your computer via a USB dongle. The unit is slightly larger than a USB memory stick with a SMA antenna connector. The frequency coverage is 64MHz to 1700MHz. It uses no special drivers and appears as an USB audio card to your PC. The FUNcube dongle works with most SDR programs that can use an IQ signal. The device is frequency agile, but at this time requires an external program to set the center frequency. We have only played with for a couple of hours, and needless to say that the FUNCube dongle is a very interesting SDR radio.

They have been tremendously popular. The FDC usually goes on sale once a week and sells out in minutes. The number that goes on sale is usually 100 units per week. We hope to spend a little more time with the device over the next …

DSP based Radio Direction Finding Project

PA3BNX ,Lodewijk Baars sent in an interesting project that he is working on. It involves using Digital Signal Processing techniques applied to Radio Direction Finding. He provides the plans, PCB layouts and software for the project. Looks very interesting! Further information can be found here if your interested in taking a closer look at the project.…

QuickSilver QS1R Receiver user Photos and Video

N9VV with his QS1R

Ken  N9VV , graciously sent in some of his photos and a video of his SDR Radio setup. He is using the QS1R Receiver that covers 10Khz to 62.5 Mhz. The QS1R is a direct sampling SDR receiver that connects to your  PC through a USB 2.0 port. Ken uses an inexpensive mITX Atom 330 PC to act as a server to the QS1R Receivers software. That way he can access it from a remote  location in his shack from another PC. Thanks Ken!
