Which are "microwave contests" ????
Microwave contests are competitions which the target is to do as many as possible
vocal/tv connections with other amateur radio peoples.
A classifications is made by computing the score adding the distance (in
kilometres) of each connection (QSO).
For Example, if i make 50 QSO with an average distance of 250Km, my score is
250*50=12500 points
The contests are organized by hamradio associations, for a specific day or
week-end, for a length of 6 to 24 hours.
Due to the score calculation method, the winner is the hamradio people located in
the best location (in the highest and most open mountain) with the best
devices (most powerful transmitter, most sensible receivers and most wide
antennas).
Usually I take part to 6-8 contests per year, from my portable hamradio
stations working in the open-air from the top of a mountain near my home,
like "Cesen Mountain" in the figure at the right.
My microwave portable station
My microwave contest stations is made by
- 85cm offset parabole with two horn illuminators ( 5.7 and 10 GHz band)
- 2x8 dipole array antenna, by I3KUH, for the 2.3 GHz band
- 26 elements Yagi antenna, by I3KUH, for the 1.2 GHz band

- Radios Control box , that permit to use the four radios by two operators
simultaneously, with the vocal automatic calling using a DAST
- 2-litre bottle of Prosecco wine, produced at
my village Col San

in the open-air for eight hours a day in the winter, on the top of a
mountain, is NOT possible without alcool!)
