Hi, Tobias.
I'm listening also. Will you be using JT9-1 or JT9-2?

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.

conversion. The amplifiers do not have to be linear for JT2 (and WSPR). In
fact I do use a class D push-pull PA.
