Hi Pete,

Thanks to all = involved,=20 and indeed it was a nice evening with almost no QRM this side (except from the 'primary = users').
9H was=20 again audible with his remarkable slow cw (but not QRSS) around 478.446 kHz.
Nice to hear / work = GI, EI, GW, G, HB9, PA, SM,=20 OK, and DL; all active = tonight.
60=20 watts output from the TX seems to be sufficient here (about 1.5 A = antenna=20 current, wire between 7 and 11 m above ground, total length 60=20 m).

73, 
  Wolf DL4YHF=20 .
