Thursday 12 January 2017, Andrew VK1MBE and Andrew VK1AD activating SOTA peak Mt Budawang VK2/ST-015, grid QF44XM. Surprising success at working ZL1 on 6m 50.120 MHz at 5 watts QRP SSB, that’s right not CW or digital modes, yep voice mode SSB from SOTA summit Mt Budawang VK2/ST-015 for two ZL1 QSOs over 2340 km (1454 miles). Mt Budawang is 37 km inland from the Tasman Sea.
My 6m gear: Yaesu FT-817 at 5 watts, antenna is a homebrew 6m 1/2 wave coaxial vertical supported by a 6 meter telescopic pole at 1137 metres above sea level (ASL)
Here is a link to an audio recording (7 minutes) of two QSOs from Mt Budawang, one after the other at 01115 and 0121 UTC. The first QSO is with Dave ZL1AKW at Tauranga followed by Warren ZL1AIX near Auckland. 🙂
Special thanks to Andrew VK1MBE for holding the squid pole. Andrew and I had arranged a scheduled QSO with Gerard VK2IO in Sydney, 214 km north of Mt Budawang on 50.160 MHz. We did hear Gerard calling but very weak with a signal report at 2-1. After listening for Gerard I tuned down the band and found a ZL working VK4 on 50.140 MHz. With that in mind I called CQ on 50.110 MHz (6m call frequency) to have two ZLs reply. The rest is history 😉

Mt Budawang is a walk up summit with an ascent of 470 vertical metres over 4.2 km. The walk is a constant grind without respite, all the way to the summit taking 1 hour and 30 minutes. With one set of radio gear, amplifier, batteries and numerous antennas Andrew and I shared the weight distribution in two backpacks. Sun shade, sun screen, ample water and food were essentials for today’s activation.
Photos of our station set up on the summit of Mt Budawang VK2/ST-015. Sorry, I forgot to take a photo of Andrew VK1MBE holding the 6 metre squid pole. I did remember take a photo of myself holding the pole supporting a 40m inverted V dipole while Andrew worked chasers on HF 40m 7.090 MHz.
Thanks Andrew for your excellent company, a great day out of the radio shack!
