I'm a regular on the ##rtlsdr IRC channel on freenode, and a lot of people use the Odroid C1(+) for it, which the specs of match pretty evenly with the A64. Complex decoding is usually on the Odroid XU3 or XU4 (far more powerful devices, though 7x the cost of the A64), though.

I also have a bet with someone on that IRC channel that the A64 benchmarks better than the C1+. Gotta wait until i get my unit though. Wink

Thanks for the reference. I was looking for a way to get FM data onto an SBC. My first inkling was to use an FM tuner hooked up to an arduino board then getting the audio via a USB sound card to the SBC.

Now I think I can just use one of the cards referenced on the RTL-SDR page to give me audio directly over USB from a tuned FM station.

I installed rtl-sdr (using sudo apt-get rtl-sdr) on my 2MB Pine64 with Debian/Mate image, and was able to stream FM radios over TCP/IP in no time.
Just run on the Pine:
rtl_tcp -a yurIPaddress -s samplerate
(replace yourIPaddress with the IP address of your Pine, and samplerate with your desired sample rate. I found 2048000 works on Ethernet connection, but for WiFi better set to 1024000), then on any networked computer run SDR# or SDR-Console, selecting "RTL-SDR (TCP)" (for SDR#) or "DVB-T dongle" as source, and voila, I can tune and listen to any radio stations that the dongle can tune in.

My current efforts is to have fully GNU Radio, with GNU Radio Companion, runs on Pine, will be posting more details on another thread.
