That's pretty much where we're at as well. The script from Edson is what we used for both Atom Smash and intend to use for Dog Pack. 

For the Atom boards, we were able to successfully copy signals using a Softrock 40. The entire process wasn't so much hard as tedious and involves tracking down dependencies. The script required some changes. I commented those lines, so I'll find them again and share. They involved the location of the jack audio libraries, if memory serves.

Let me see where we left off mid-summer on the Beagleboards and report back. With school starting again in the near future, I should be able to pick back up.   :+)

More soon, -Michelle W5NYV

The Beagleboard's is onboard so I have changed the device number to BB's defaul hw:0. Again what I am trying to do is get a signal displayed on SDR-Shell. Edson mentions qjackctl I never came across that anywhere in the documentation to date so if you have some info on what that

This is using a USB/Serial adapter for PTT to the rig and audio in and out for RXTX. All of which worked upon installation with no setup. so I know the hardware is capable of doing everything.
