SOTA – Lunch Box SHF at Booroomba Rocks

Saturday 16 May 2019. I am joined by Andrew VK1DA for a joint activation of Booroomba Rocks VK1/AC-026 at 1382m ASL in Namadgi National Park. Starting from Booroomba Rocks car park, the ascent to the summit is 267 vertical metres over 2.4 km taking one hour. Andrew plans to qualify the summit using CW in the HF bands, while my interest lies in the higher bands, 2m, 23cm and 13cm.

One thought on “SOTA – Lunch Box SHF at Booroomba Rocks

  1. Looks like a lot of fun, my local club (Meriden Amateur Radio Club) just did our first SOTA a few weeks ago, operating just 2M FM from Sleeping Giant in New Haven CT and we plan to ‘go large’ in 2020 with more activations including HF…73 de AB1DQ
