Dear Jim,
I'm quite surprised from your report because my power last evening was
80 W in antenna !!!
This evening  i will start later at 20:30 UTC untill about 22:00 UTC
with  40W.


P.S. the half hour transmission delay was due to solve a little
last-minute problem in atenna feed.


Tnx and '73, Valerio
