Hi Mario,

W4ZV> K1UO has a single vertical.

 >Do you know how far is his vertical from the sea?

         Closest sea is approximately 30 km toward SSE direction but
about 500 km toward NE direction (Europe).

         I disagree, especially on 160m where groundwave is extremely
strong.  I have a neighbor ~3 km away who runs 100w to an inverted-L.
At S9+45 on the Orion, his signal is by far the strongest of anyone,
and routinely desensed my FT-1000MP whenever he came on the band.  Just
imagine how my 1.5kW and .35 wl vertical must sound to my neighbor!
I live in a rural area, 3 km from a very small town (population 400),
but imagine if I lived in a more crowded area like the NE USA or EU!
In Colorado I also lived in the country, about 5 km from a town of
population 5000, but was also within 6 km of K0RF and 3 km of W0YK,
both running 1.5 kW...and both easily desensed my TS-930S on 160m.

pile-ups :-)

         Congrats!  As I said before, winning contest scores are the
combination of many factors (operator, antennas/equipment, location,
etc).  My point was that Orion is certainly not a handicap and is
most likely an advantage in the hands of a good operator with good
antennas and a good location.

                                                 73,  Bill  W4ZV
