[Moon-net] IK2MMB 10GHz moonbounce

[Sergio]

For the pleasure of it, I'd like to inform you about a successful 10GHz 
EME qso between myself and IQ4DF.  The interesting thing is that I used 
my home-made mesh dish that normally I use for 1296.

The antenna is doing quite bad in 10 GHz but I still evaluated a 40dB 
gain which is equal to a 5 to 6% efficiency only for a 12 foot dish.
Basically an average performance of a 6 foot or so dish.

The  antenna pattern is obviously full of sidelobes but I still liked to 
give it a try.  After few failed attempts, on April 1st (this is NOT a 
1st April fool) we were able to have a full qso. The qso merit goes to 
IQ4DF of course with all those gears on their side, but I'm still very 
proud of it.  I consider myself like a 'yagi' station for 10GHz , hi.

BTW the weekend before the qso I also heard another station, it must 
have been Alex AW but the weather was so bad and echoes were very 
marginal also from 'DF that day.

The receiver here is pretty 'sharp' with a 0.65dB NF in WG, the power 
used was only 27 watts, the 60w brand new TWT seems not working 
anymore... Both the receiver and tx are unfortunately behind a 0.5-0.6 
dB waveguide loss (for now).

I will post pictures and recordings on www.crbr.it within this week.

Dreaming for a better dish,

IK2MMB

p.s. Thanks to all my friends and clubmates at IQ4DF!
