I think this is a very promising project though for slightly different reasons.
I bought a single one for $495. It is open source firmware so can be adapted
to report, for US projects, more information over a greater performance
envelope than other commercial solutions.
It does work though it's sensitivity with current firmware is materially less
than desired. A promised firmware update will increase Rx sensitivity by 20 dB
which will be just fine methinks. It is alleged that it is up to 10g
acceleration tolerant. It is power hungry since the core acquisition chip is an
FPGA.
Promising.
