Chasing Herbert OE9HRV from Mt Stromlo in Canberra

Saturday 26 December 2015.  Earlier today I noticed a SOTA alert posted by Herbert OE9HRV seeking VK Dx on 10m 28.477 MHz SSB.  2 months ago Herbert wrote to me suggesting I substitute my 10m 1/2 wave dipole for a 10m J-Pole.  Herbert went even further than a recommendation, he mailed to me a complete hombrew 10m J-Pole ready for use.  Herbert’s only request was that I use the antenna to call him for a S2S on 10m.  🙂

Having spotted Herbert’s alert on SOTAWatch for 0730 UTC (18:30 local) I posted an alert for Mt Stromlo VK1/AC-043.  If you know anything about Herbert’s SOTA activations you may recall he often operates his radio at 150 watts output powered by three 8.4 LiFePO4 batteries. Herbert’s antenna choices usually involve 1/2 wave verticals either in the J-Pole or ‘H’ antenna configuration.  Check out Herbert’s set up at Herbert OE9HRV.

My equipment:  Yaesu FT-857D, batteries 2 LiPo batteries, antenna OE9HRV 10m J-Pole.  Radio power setting 25 watts for VK chasers and 50 watts when I called Herbert.

Did I work Herbert OE9HRV on Hirschberg OE/VB-509 in Austria from Mt Stromlo in Australia?  No I didn’t.  Did I hear Hebert?  Yes I did from 07:50 UTC through to 0900 UTC, Herbert’s signal was consistently 5-2.  When Herbert called CQ on 28.477 I returned his call many times, unfortunately the FT-857D at 50 watts output wasn’t enough for a contact via short path.  Interestingly Al VK1RX/M mobile in Canberra heard Herbert.  Al and I also heard DK8MZ (non SOTA station) calling CQ VK and ZL short path, his signal was 5-5, again I return his call without success.

Who did I work from Mt Stromlo?
