[Skimmertalk] Anyone got this to work?

The Red Pitaya WSPR Transceiver appears work the same, uploading spots to
http://wsprnet.org/drupal/wsprnet/spots (WSPR version of the Google map
<http://wsprnet.org/drupal/wsprnet/map> is broken, same as on
reversebeacon.net)

Complete description here:

For 125-14 (8 bands):

For 122.88-16 (16 bands):

https://pavel-demin.github.io/stemlab-sdr-notes/sdr-transceiver-wspr/

But the day/night rotation scripts of SM7IUN are only for the FT8
transceiver, not the WSPR one, though I imagine the same technique could be
used, if there is any demand for that.
