Wally Howse VK6KZ/4 (the traveller!) 
and VK4OE extended the existing
VK4 distance record for the 10 GHz band.

The existing record was established when 
VK3XPD, VK3ZQB, VK5NC and VK5DK
did their multi-state microwave 'bash' about three years ago.

VK6KZ/4 set himself up on Springbrook Mountain 
on the VK2/VK4 state border in behind the Gold Coast, and 
Doug VK4OE travelled three and a half hours by road up to Hervey Bay 
to a vantage point near to where Glen VK4TZL lives. 

The path is about the longest that could be considered in South-East Queensland
which has minimal 'terra firma' intervening between the two locations.

After the usual (and necessary) 
careful setting up of dishes and finding correct beam headings, 
Wally was hearing Doug's carrier and after final optimisation, 
they exchanged 3/1 and 4/1 reports on SSB.
Quite characteristic fast QSB or 'wobble' in signal strength 
over a path of approximately 330 Km, which is way longer than line of sight.
Propagation could not be regarded as particularly enhanced on the day,
but there was a slow moving high pressure ridge 
aligned with the Southern half of the Queensland coast at the time.

Equipment was pretty similar at each end, 
being about one watt transmitter output fed to dishes around 600mm in diameter,
and HEMT LNA's ahead of what are essentially 
G3WDG transverter systems and IC202 tuneable IF's.

Quite a thrill and reinforcing of efforts to
'push the limits' even further, much more is possible!
There are lots of good experiences available in the microwave area,
as everyone who has already discovered it will confirm !
In an earlier attempt VK4OE did hear his signal (very weak)
when an aircraft was on direct alignment with the beam.
Maybe there is more research and possibilities for aircraft enhancement 
on uWave bands, not just VHF/UHF.

QNEWS understands Rod VK4KZR and Doug VK4OE are 
building 24 GHz narrowband gear and one of their aims is to
'steal' the distance record for that band back from the VK3's and VK5's 
who set it at the same time as the 10 GHz record a two or three years ago.
