Using the Airspy on an Odroid C2

The Odroid C2 is a $40 single board computer with a 2 GHz ARM-A53 quad core CPU and 2GB of RAM. Compared to a Raspberry Pi 3 it is more powerful and costs about the same. The Airspy R2/Mini is a $199/$99 USD software defined radio that can tune from 24 – 1800 MHz, uses a 12-bit ADC and has a bandwidth of up to 10 MHz. The Airspy wesbite generally recommends that a relatively powerful 3rd generation Intel Core i3 2.4 GHz processor is required for the Airspy.

However, recently the Odroid C2 has proved itself powerful enough to run the Airspy in full 10 MHz mode in GQRX, though without demodulation. On his website Michael DG0OPK shows some screenshots that show the Airspy+Spyverter upconverter combo running on an Odroid C2 and demodulating with the WSJT-X software, running GQRX and running as a spectrum analyzer.

Over on YouTube user radio innovation has also uploaded a video showing the Airspy running GQRX on an Odroid C2.
