Some of us at sudo room / east bay mesh are working on a low bandwidth disaster recovery mesh project based on software defined radios.

We're prototyping with a combination of USRP1 and RTL-SDR devices and GNU Radio.

We're having some issues getting the receivers to demodulate our data streams (using DQPSK and QAM modulation).

Does anyone have experience with such matters and if so, would you sit down with us and help debug our setup (or even join the project)?

Willing to meet at either noisebridge or sudo room. We'll bring the food and beer.
