Completed a 2403.1MHz trial with Doug VK4OE today. We started with the path between VK4CZ and VK4OE, knowing that there would be some terrain issues.

I was using Doug's 3-in-1 box... and 144MHz txcr/IF with 2.4GHz and 10GHz  transverters in one handy box. Although we had a reasonable copy of each others carrier signal and we could detect each others SSB signal when transmitting, the path was unworkable.

Located on the drive near the front door. Power sourced from the ride-on mower!

The small 2.4GHz yagi with the 144, 432 and 1296MHz yagis in background.

A quick decision was made to establish VK4CZ/P and relocate the equipment to the corner of Eatons X'ing Rd and Clear Mt Road and a slightly better result was obtained, but still unworkable on SSB. A further shift to the Clear Mountain 'lookout' was made and a very easy QSO was completed.


Doug's signal was easily over RS59 on carrier and on SSB varied between RS51 to RS59 on peaks.

Doug's small  13el 2403MHz DL6WU yagi.

All good for the Brisbane uWave Activity Day this Sunday - weather permitting! And I will trial my 24el 2403.1MHz DL6WU yagi!
