Three summits on Mt Buffalo: The Hump (VK3/VE-019), The Horn (VE-014) and Mt McLeod (VE-034) 2017

The annual Australia Day holiday, Thursday January 26th 2017, set up an opportunity for a break and some alpine walking and activating.  Leaving Melbourne on Wednesday 25th I drove to Mt Buffalo and camped at Lake Catani on the Mt Buffalo plateau. Mt Buffalo is a mountain plateau (1400 meters) and national park, about 350 km north east of Melbourne.  This is a sub-alpine camp site which must be reserved ahead of arrival with Parks Victoria. There are lots of good camping spots under low snow-gums, a pristine fresh water lake that you can swim in, hot showers, no drinking water, and (apparently) a population of endemic dingoes.  Just down the road is former ski spot Dingo Dell, where I’ve ski’d many years earlier.  I had no idea that it is named after these Australian native dogs.

Mt Feathertop (VK3/VE-002) 2017

Mt Feathertop (VK3/VE-002), 1922m, 10 Points, is the second highest mountain in Victoria.  Along with Mt Bogong and other summits and highlights along the Australian Alps Walking Track it is a popular hiking destination for more experienced and fit bushwalkers.  A number of sites offer advice and information for climbers.  So far there have been 6 SOTA activations (since first activated by Wayne VK3WAM in 2013).

More power to the activator (choosing a new LiFePO4 pack)

When the time came recently for a new battery, I jumped onto HobbyKing and was bewildered by the range of options, even after limiting the search to a particular current capacity, in my case 4-5AH, and 4S (4 cells). Wishing to leverage the ‘wisdom of the SOTA crowd’, and at risk of reopening the “whats the best battery for SOTA” chestnut, I posted to the yahoo SOTA_Australia group:

I’m buying another LiPo from HobbyKing. This battery will be for general purpose 5 watt txcvr use, but will also be used to power an afterburner of the W6JL type, using a pair of IRF2Z24N hexFETs, for up to 50 watts. My question is, what do I make of the discharge figure on the LiPo packs, which varies from 10c to 35c? I presume this is the rate at which the battery can supply current under load, the higher the better. A higher discharge figure might be important when powering an afterburner, which might draw current peaks of many amps on voice peaks. Prices seem to correspond with higher discharge figures, from as low as $25 (10c) up to $55 (35c) for packs around the 4AH rating.

My only current Li-XXX asset.

Mt Torbreck (VK3/VN-001) and Pyramid Hill (VK3/VN-005)

Mt Torbreck (VK3/VN-001) is the highest peak in a cluster of four SOTA summits in the Rubicon State Forest, south of Eildon.   I planned to leave plenty of time for it as several activator’s blogs gave me the impression that there was a climb involved.  Having another 8 point summit not far away was added incentive for climbing Torbreck in the morning.
