With the first attempt of the activation, the day before, no QSO had been transacted.
But with the second attempt I could transact then those at least four QSOs owing to HB3YAT/P, HB9AGH, HB9MKV and F5NPK/P.
F5NPK, Hubert was willing to stop his car ride in order to go home and to make my 4th SOTA QSO with me. He was using 1 Watt on the direct QRG on 2 meter.
Thanks to all!
