Philip,What distribution does your work revolve around? I have been back and forth trying to compile (or just install) various SDR applications on both Angstrom and Ubuntu. I have tried using OE, bitbake and that methodology, to little availe. Also I have tried to install FLdigi which should run very well but depends on Hamlib which, in turn is dependant on gcc which I now realize has its own series of problems. So that may not be an ultumate route to take. Also, I have many of them running perfectly in Ubuntu on my Intel box so how hard would it be to get them to run on the Beagleboard if that is the case?
Angstrom :) It takes some practice, but once you get OE building Angstrom, life is much easier.
Koen Kooi seems to maintain that most SDR software including Gnuradio will not run efficiently on anything but Angstrom on the Beaglebord. Looking a the face of it I am inclined to agree but also am reserving judgment since his work with Angstrom may make him less than objective! :)
Not all the distros are compiling for the armv7 instruction set available on the beagle.
Also concerning Gnuradio, it appears to be a series of modules that one can put together to have an operating radio but does not, as far I I have seen, do any kind of translation from the various modes (PSK, CW, RTTY, etc.) back into text that is the norm for Digital Packet communications, at least insofar as we hams look at it. Are there any provisions for such? Has anyone done any work in that area that I am just not aware of? Thanks for your guidance and assistance.
I'm not aware of much amateur radio specific stuff on GNU Radio.I'd like to get the existing amateur stuff running on the Beagle, but it is yet another background task for me. Koen added hamlib to OE the other day. I think fldigi had some issues that were going to need more attention. Once something from the x86 world is built on the OMAP3, there is likely some work to do on the actual signal processing code.

My current goal is to have some way to build GNU Radio that is better than the current process by Friday, and update the OE default to gnuradio-3.2. This will include USRP1 support and basic NEON support. This should work on the Beagle and Overo boards. This should make things much easier for people.
