    I'm using a Raspberry Pi 3 and GQRX software for software defined radio. Easy to load the required files and the GQRX google groups people (especially Alex, the author of GQRX) are willing to help setup. The GQRX software typically runs about 45-50% of CPU time and a heatsink for the CPU is recommended. The download of 2.6 version is at gqrx,de .. It supports a bunch of different inexpensive RTL USB sticks. I'm using a NooElec stick and an upconverter with great results!

    Hi Jim,

    Is there a way to pipe the signal from GQRX to another application on the RPi3, a virtual audio cable of sorts?

    My goal is to have a self-contained WSPR/JT65/JT9 receiving station. The RPi3 works fine with WSJT-X, but it still needs an external receiver. I want to use an RTL-SDR dongle instead. GQRX works fine receiving FM broadcasters.

    The missing link is the virtual audio cable part.

    You better check on the GQRX forum. I'm Alex would have that information. I'm only into GQRX by one week...
