Hi,

I've been trying for a few days to spot wspr signals on 20m with no joy.

I'm using a rtl-sdr usb dongle, RTL2838 DVB-T, with a 50MHz upconvertor. I'm in Ireland and have previously received audio from Portugal/Spain using the same setup. I have a 20m wire antenna and 9:1 unun.

I have been tuning the dongle with gqrx on Ubuntu 14.04, 14.0956MHz/USB, and piping the output to wsjt-x.

No joy yet. I've two questions really. First is for any general pointers that may help me in right direction? The second is that someone would send me a wav file with wspr signals? I discovered I was missing a decoder when I ran the wsjt-x sample files but these seem to be just for JT9/65. It would be good to confirm there are no wspr decoding issues I'm unaware of.

Many thanks,

Chris
