Projects Using Gumstix (tm) Products:
Unfortunately, the TSCM Receiver Project had to be canceled.
The GnuRadio series of hardware are truly remarkable tools for academic research.
It turned out that for my purposes it simply wasn't viable for use as a commercial product.
There are several very good TSCM software receivers currently being developed by others on custom hardware.
should add that the people at Ettus Research and the GNURadio open
source community have been EXTREMELY helpful and patient.
