Jusr did a test transmission and saw on PSKmonitor that my signal is copied=

Hi Tobias,

I just installed the most recent version of WSJRT-X and I'm listing on 474.=
2 kHz dial / 1380 Hz audio.

Hi Rik !

Sven and me had been working on 1380 Hertz Audio and the standard
474.200 kHz Dial. The Idea behind was, that there might be some Hams
around seeing a signal just below the WSPR passband and beeing curious
enough to explore whats going on there. Just to raise some more stations
to join in.
