First Post - What kind of SDR are you using?


By JamesBrown - Posted on 20 August 2009

What kind of SDR are you using or planing to use? I have an HPSDR up and running on my Windows Vista machine and am writing a device driver in Delphi to match the rest of the software in my station. See it here: SETI Net Regards....... Jim

I agree about the complexity, but what a powerful platform. The GNU Radio Companion (GRC) seems a fairly straightforward tool to at least get started. I myself do not have a USRP (yet), but have used GRC for other projects. Still getting my head around building the Python wrappers for customized blocks, but doesn't appear to be particularly difficult. Another possibility might be Berkeley's Ptolemy II. I've been able to build algorithms (SDF domain) and, when convinced they were working, generate corresponding C/C++ code that easily compiled for my TMS320C6713 DSK.

Hi, im using an SDR-14 from RFSPACE on Windows 7. Primary for 1420Mhz spectrum analysing. regards, Karl-Heinz DL6EBS
I have a USRP working with gnuradio. The problem with this great product is its complexity. I'm still learning about it. Cameron

Several SARA members have Software Defined Radio (SDR) receivers. The complexity/learning curve is intimidating and we need to write some recipes and a project summary to help get up to speed. This is an extremely important area for us.

The SARA board and others just concluded (Jan., 2011)active threads of perhaps 30 emails about how SARA might want to encourage development of an SDR that would be optimized (technical capabilities and cost) for amateur radio astronomy. My thanks go to Marcus Leech and (SARA V.P.) Paul Oxley for their leadership.

Resolution is this:
* The administrative thread is on hold.
* We setup a SARA google group on this topic, but the administrative discussions didn't migrate (yet).
* The technical development thread stayed on rf-sampler@yahoogroups.com, where people can contribute to the ongoing development. If you join, please read the correspondence to get up to speed.

Cheers, David Fields

SDR is very beautiful and simple yes. I suggest you experiment. If you find the proper frequency, the crystal blocks, your work is easy. Circuit works with a computer and sound card. Is cheaper. Sample Calculation ... Target frequency: 7200 KHz. 7200 * 4 = 28 800 kHz. Block crystal value: 28 000 KHz.
