Ian,
While I am unaware of how qualitative the Lime Micro Systems Chips are, what worry's me about these GNU Radio / USRP Alternatives: > - Fairwaves UmTRX > - Lime Micro MyriadRF > - Loctronix A-2300 Is that all the above listed SDR devices utilizes a 1 product company, and the last one we had was Elonics who produced the famous RTLSDR stick. But Elonics is bankrupt, so whoever is purchasing / designing around those chipsets, I'd be nervous. Also, for the price of just 1 Lime MicroSystems chip, $110 as of this date, is still $30 more than purchasing 2 Analog Device chipsets who offers you MORE Radio Frequencies. The BladRF & ALL of EpiqSolutions products suffers from this as well as they utilize the Lime Microsystems Chipset. I avoid purchasing Ettus Research Products since he he got the Open Source Community to design applications around his USRP that he claimed to " Release the PCB board layout files " but never did. Its documented here: I also got the schematics for my TV set and my video recorder. But that's for service and repair. It's not free hardware. As far as I know the USRP designs are copyrighted and not under a free hardware license. Correct? http://lists.gnu.org/archive/html/discuss-gnuradio/2011-01/msg00533.html Other than that, the UmTRX is what I'd purchase as your purchasing the support/brillance of the Russians behind it.
