National 134GHz Record Smashed
Date : 16 / 07 / 2020
Author : Robert Broomhead - VK3DN
The national 134GHz distance record has just been smashed, previously sitting at 3.8Km it is now 19Km.
The distance record attempt took place on the 11th June in Victoria during the break between Covid lockdowns.
The new record was achieved by Andrew VK3CV and Noel VK3NH between Sky high restaurant on Mt Dandenong and
the base of the fire lookout tower at Kangaroo ground, a distance of 19 Kilometers, smashing the previous
National 134GHz record of 3.8Km achieved by VK4CSD and VK4FB in December 2019.
The weather conditions were average, Mt Dandenong, 8 deg C, 80% RH , 1025 mB and Kangaroo Ground 7 deg C, 75% RH, 1025 mB.
Whilst Andrew located at Kangaroo Ground could see the Sky High site, Noel had no visibility of Kangaroo Ground
due to the mist (as pictured above), so had to search in the general direction through a gap in between the trees
until he heard his unit operating in beacon mode on CW. They then proceeded with a contact on FM mode.
As with the 122GHz records again the equipment was designed and built by Andrew.
The equipment is a prototype for the next generation dual band 122G / 134G VK3CV system currently in development
and using newer Silicon radar chips which will eventually cover both bands.
These particular systems only cover the 134G band as the chips used are non-released engineering prototypes.
Distance records are kept on the WIA Website under the 'For Members' menu select 'VHF UHF Records'
