ARLX001 10-GHz record claimed
 
Roger Bowman, VK5NY, and Walter Howse, VK6KZ, have claimed a new
world distance record on the amateur 10-GHz band.
 
On December 30, 1994, the two worked over a path of 1911 kilometers.
Both VK5NY and VK6KZ were portable, the former near his home in
Adelaide and the latter portable near Perth.
 
VK5NY used 180 milliwatts to a 400-mm dish while VK6KZ ran 100 mW to
a similar antenna.  The 2-way contact was on SSB.
 
The previous 10 GHz record of 1018 km was held by WA6CGR and
XE/N6XQ.  N6CA and KH6HME continue their efforts to span the 3973-km
path between California and Hawaii on 10 GHz.
 
Howse said there was a typical high pressure cell in the Great
Australian Bight, a large inlet body of water, and that good signals
were present over the 1900-km, nearly all-water path on 144, 432,
and 1296 MHz.  On the second night, VK5NY drove 250 km to another
location in an attempt to once again increase the record distance,
but no contact was made.
 
VK6KZ reports hearing, and being heard by, David Minchin, VK5KK, a
few km farther than VK5NY, but no 10-GHz 2-way contact resulted.
 
VK6KZ lives about 1000 km (some 600 miles) from his portable
location near Perth, and must drive there to make these attempts at
UHF records.  ''I have to choose the right time.'' he said.
