35 MHz interference update -- Dave Armitage

ICASA have recently done a survey at Midrand Model Soarers field to ascertain what was causing some heavy interference on certain spots in the 35 Mhz band. It was found that ESKOM seemed to be causing the problem with arcing on some of their ultra high voltage power lines. I have requested a full report from ICASA. At present they state they have informed ESKOM of the problem. ICASA want to do another full test at the site before issuing a report. On receipt of that report then I will make it public.
Another site that seems to be experiencing some frequency related problems is JOMAC. This site is also near a heavy concentration of high voltage power cables. It could just be possible that the same sort of hassle could be happening there.
I am awaiting fault reports from pilots at JOMAC before initiating a survey there.
