I have a few catch-up posts (2m and 23cm) to complete for this blog. I will do so in the next couple of days.

SOTA VK1AD – April 2021 2m – 23cm activations
The purpose of this post is to share information with fellow radio amateurs, which demonstrates how you can achieve VHF-UHF Dx contacts with as little as 5 watts output on 144.200 MHz and 2.5 watts to 25 watts output on 1296.150 MHz.
Yes, you can also qualify a SOTA peak with a mono or dual band HT on 2m and 70cm. You can achieve greater distances with the use of an external antenna such as the 2m 4 element Yagi

SOTA VK1AD – January 2021 2m – 23cm Activations
The purpose of this post is to share information with fellow radio amateurs, which demonstrates how you can achieve VHF-UHF Dx contacts with as little as 5 watts output on 144.200 MHz and 2.5 watts to 25 watts output on 1296.150 MHz.
Yes, you can also qualify a SOTA peak with a mono or dual band HT on 2m and 70cm. You can achieve greater distances with the use of an external antenna such as the 2m Oblong Loop antenna.

SOTA – Snow Gum Mountain on 23cm
Sunday 24 May 2020. Andrew VK1DA and I have chosen two summits for the day, first Mount Wee Jasper VK2/ST-017 1121m ASL grid square QF44HU followed by Snow Gum Mountain VK2/SW-028 1179m ASL, grid square QF44IR.
Snow Gum Mountain
Snow Gum Mountain is 11.5 km line of sight from Wee Jasper, however the route between summits is convoluted through pine forests. Travel time is approximately 45 minutes.
Until recent times Snow Gum Mountain hosted a VHF VOR/DME air navigation facility. The VHF DME was decommissioned, all communications infrastructure have been removed from the site. The site is now a drive-up summit, there are no signs, gates, barriers, buildings or fences. The mountain peak has been returned to nature 🙂
The view of the horizon is an uninterrupted 360!

SOTA – One Tree Hill on 23cm and 13cm
Wednesday 30 October 2019. Left work at 16:30h for a 30 minute drive to Hall township. The walk to the summit is 5 km taking 50 minutes, my plan is to start the activation by 07:15 UTC (18:15h local). The last 300 metres is quite steep, lots of steps to climb 🙂
Sunset is 08:30 UTC (19:30 local), the return walk to the car will be in the dark 😦
Ambient temperature is 30 degrees C.
My objective is to qualify the summit on 23 and 13cm with local VK1 SOTA chasers.
Navigation – ACT Centennial Trail 7 November 2013
The trail starts at the intersection of Hall Street and Hoskins Street, Hall township.
Start here – One Tree Hill lookout trail
View north – One Tree Hill is the furthest summit to the north, 5 km
track condition is good, it’s popular with walkers and MTB riders
One Tree Hill lookout – great view south to Canberra city and beyond.
Lookout platform supporting my 2m 145 MHz rectangular loop antenna
SG-Lab 23cm (1296.150 MHz) and 13cm (2403.150 MHz) transverters and PCB antennas. Transverters are operating barefoot at 2.5 watts output. FT-817 IF frequencies are 144.150 MHz and 435.150 MHz respectively.

SOTA – Honeysuckle Creek on 23cm
Sunday 13 October 2019. Wade VK1MIC and I have chosen a difficult climb to the summit of Honeysuckle Mountain, Namadgi National Park. The forest regrowth is very thick with no formed trail while the ascent grade is quite difficult at 20%, check how close the 10m contour lines are to each other 😦
Correct attire for this bush bash is leather hiking boots, long pants, long sleeve shirt, hat and leather gloves to protect the hands.
