I bought a HackRF One SDR recently. The first thing I wanted to do is to try WSPR, which checks for other WSPR beacons to help monitor propagation paths.
I set this up using the free SDR software SDR# and another software virtual audio cable to connect the two.
That much was easy enough, but I have not had a single connection, running it for a bit over a week. WSPR frequenctly says it’s decoding, but nothing pans out. I am using the antenna that comes with the HackRF, which isn’t great but I hear others have had success with it.
I probably have something set up wrong still. I think I need to use CW mode in SDR# for WSPR but have not actually found confirmation for this anywhere. Since it’s not working it’s likely wrong :-)
You need to use USB for WSPR.
Frequencies to tune to are:
0.136, 0.4742, 1.8366, 3.5926, 5.2872, 7.0386, 10.1387, 14.0956, 18.1046, 21.0946, 24.9246, 28.1246, 50.293, 70.091, 144.489, 432.300, 1296.500
Try 7.0386 to start with, if your antenna suits, as you’ll likely have more success with this – Local contacts during the day, and long distance contacts at night.
