Hi EME gang, we have again big problem with the wind in Geneva. Last Moon 
pass we were able manage only 10 QSOs on 10 GHz and 4 QSOs on 1296 MHz 
before we were hit by strong wind which peaking 60km/h. First problems I was
able recognize during CW 3cm QSO with Gerard PA0BAT when I suddenly did not 
see Moon noise on SDR. I lost Gerard and we were repeating QSO in couple 
minutes later. Than situation become worse and worse and we had terrible 
problem keep dish pointed to the Moon. Moon noise I have 1,2 - 1,3dB, but 
that moment it was vary from 0 to 1,3dB. Situation result with parking and 
anchoring both antennas. I was checking situation every 1 hour on the roof 
and no improves were observed. Early morning I decide to sleep little bit, 
because I was so tired. I have to apologize every one who was waiting for 
us. You can see the situation across EU where is so windy now. Weather 
forecast for Geneva says that in Tuesday wind will be peaking up to 80km/h. 
We are very scare, that it can to become early and we will have problems 
with antennas.

 
 
For next Moon pass we propose this and hope that we will be able to manage 
all according this plan.

 
 
Now we have prepared 2320 MHz in the 3,2m dish. 5760 MHz in 180cm dish. Wind
calmed little bit down now and we hope that due to wider radiation angle of 
6cm band we can to work via Moon many of you. We do not know what happen 
during Moon pass from Sunday to Monday and in this reason we want to operate
13 and 6cm together give a chance everybody work us on those bands. You know
that I am positive tuned, but this situation is seriously not good now. On 
180cm we are able manage to change also to 9 or 3cm, depend of wind gusts. 
So if anybody wants to work us on those bands, please be on HB9Q and let us 
know. As I say, we will try to do our best, because nobody knows what will 
be on Sunday night when is main day for 6cm operation.

 
 
I am again very much sorry about that, I can fight technical problems, 
mechanical problems, interference but not weather.

 
 
Sorry again and we will do our best here.

73 from Geneva
