SOTA activation at Mt Stromlo, Canberra – 22nd March 2013

I was running late for this activation and had not been up to the mountain for quite a few years.  In fact I had not seen the level of destruction by the 2003 bushfires, I might have postponed seeing that because I had heard and read about it.

The mountain has a restaurant on it which is apparently open at night.  There are sometimes stargazing events open to the public.

Access to the summit is limited by a security gate which is closed to uphill traffic at 6pm.  That gate is a fair way down from the summit so if you can go a bit further uphill it will save a lot of walking.  I parked just below the gate and walked from there.  It took me about 25 mins to get to the area I operated from, which was on the side of a fenced water reservoir.  I only used 7 Mhz ssb and 14 MHz CW for this activation.  I had about 10 contacts on 7 Mhz and then about the same number on CW on 20m, including contacts into Germany, Finland, the UK and New Zealand.

Signal reports received on 20m were low and I need to improve my signal strength on this band.  I have a few ideas I need to try out.  The best simple low antenna for dx contacts is a vertical, but it needs an effective ground radial system to be efficient.  I am probably going to try using 3 elevated radials, about 1m above ground.  The squid pole is a good support for the vertical radiator and as it only requires 5m of vertical radiator, the radials can be almost 2m above ground, further reducing ground losses.

On this activation I found I was being attacked by mosquitoes especially once it got darker.  I had not had trouble with these on earlier activations and my fellow SOTA activator Andrew VK1NAM also had lots of mossies on Black Mountain this evening.

No photos as I got there too late.

Closed down after the contact with ZL1KLP at about 7:45 local time, quite dark by then. Have to make the most of daylight saving while we still have it.  DST end date 7 April 13.
