On a PC spectrum display such as the Argo software

WSPR
messages look something like the screenshot below when received locally (or usually worse,
because you probably are over-driving your receiver when receiving your own signal!):
WSPR decoding takes place in the WSPR program by K1JT (see
http://physics.princeton.edu/pulsar/K1JT/wspr.html
). Below is a screenshot showing the WSPR
2.0 screen following reception of a few transmissions (output frequency = 1,500Hz, Frame = 02,
Start = 00).
A number of other software packages are now also capable of decoding WSPR transmissions.
NOTE: the GPS interface is connected in parallel in the circuit, with the paddle. Therefore, you
should NOT have the GPS connected, while operating the radio as an ordinary CW transceiver. If
you do, the GPS serial data and 1pps will key the transmitter! Disconnect the GPS before using
the radio as a CW transceiver.
