[Scan-DC] RPI SDR dongle fun

[Alex Fraser]

I got a SDR (Software Defined Radio) dongle working on a Raspberry PI 3b 
single board computer. I let it run for hours and it seems pretty 
stable. The Pi 3b don't have enough computing power to run the dongle at 
full 2 meg bandwidth, but I understand the Pi 4 does and I'll try one 
today. The software I'm using (GQRX) has minimal remote operation, but 
there is other software which can be used with a remote GUI (Graphical 
User Interface)! WebSDR works that way and it will run on a RPI 
(Raspberry Pi), not sure if you have to join their network.

I'm thinking it would be nice to use the WebSDR or software like it to 
control the PI at the top of a mast powering it with POW (Power Over 
Ethernet). Mounting it right at the antenna I could avoid feed line loss 
altogether.  Has anyone tried this?  Problems?  What software?
