I'm a radioamateur since 1974.
In the past I was very active on 144 MHz band (only dx: CW and SSB) via tropo, meteor scatter, EME, etc.
Still interested to square hunting (look here) on 2m, from 2003 I'm very active on 10 GHz (tropo and rain scatter).
Anyway in the past a lot of work also on 50 MHz...
On July/August 2010 T70A (the San Marino republic radioclub) with the help of T77C - Tony - will be QRV on 10 GHz band with my old system composed by:
7 W solid state PA
HEMT preamplifier
85 cm offset dish
German beacon:

3) hrd it on 16/07/2009 : audio file
