Hello Tobias,

 what frequency do you use for JT9?

Hi Rik !

A second station will be Sven DF2FF, we have just done some tests with
the new version of WSJT-X and had some QSOs. He is using a Softrock
RxTx6.2 as I do.
After 20:00h UTC conditions might be good enough to try some QSOs?

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