Using https://www.tapr.org/kits_20M-wspr-pi.html WSPR TX Shield.

Software: https://github.com/JamesP6000/WsprryPi and Raspbian Jessie

If it keeps crashing after a few times, read https://github.com/JamesP6000/WsprryPi/issues/10

Works well.

Try sudo wspr -s -o -p -4.5 callsign locator -r 20 20m 0

Txs every other.

I got the Softrock Lite II rx working on 40m using PowerSDR-sr40 v1.9.0, Virtual Audio Cable 4, WSPR2 and
half g5rv facing SW, on a Windows XP laptop. It's a bit deaf compared to the IC-706 but more fun :)
Thanks to all for excellent software, great sdr guides and help on the Net.
