SotaBeams Dipole Traps

A couple of months ago, the SOTABeams Facebook page Posted a link to a new item they had just finished making. A simple pair of lightweight dipole traps for portable use to help with running multiple bands and the band changing efforts. I had built a link dipole last year and this works well, but if the…

Sota Activation – VK3/VE-204 The Paps

Work took me into country north eastern Victoria. A long day of tasks and driving, a 700km loop! I packed my sota backpack into the car just in case i had time to drop past a summit and undertake an activation. I actually ended up on two summits. I had to visit an air services…

Sota Activations – New Years 2015.

Sota rules allow one summit activation (for the activator points) per calendar year, and the program runs to UTC time. In Australia we are lucky that we are 10(11)hrs in front of the UTC date line, our new years eve change over is 11am normal people time! SO.. I lined up the family for the…

Sota Activation – Mt Alexander VK3/VN-016

The other day, I had to head to Bendigo for work, so packed the SOTA gear in the car for a quick late afternoon activation on the way home. Mt Alexander VK3/VN-016 sits just south of Bendigo and has the local TV and FM transmitters sites on the top of it, also a tower form…

Tuning the dipole using the 1:1 Balun

I had some time yesterday afternoon to tune up the wire i am using with the 1:1 Balun dipole project. I set myself up outside and ran out the dipole as I would deploy it for a SOTA activation. The antenna was too long as expected given how I had cut the wire!   I started…

1:1 Current Balun

To Balun or Not to Balun, this is the question? Like Ford vs Holden, Canon vs Nikon or Yaesu vs Icom; the world is divided into two camps on how best to connect a resonate wire antenna to a bit of coax. Until now, my dipole had been direct connected. and this had worked as…

Sota Activation – VK3/VC-022 Mt Cowley 2014

Work took me back to western Victoria yesterday, with an early morning meeting in Warrnambool which meant a very early morning trip form Melbourne. Having finished all my tasks by mid-day, I took the opportunity to undertake some RF survey works taking the coast road back to Melbourne, looking at some site options for some…

Sota Activation – VK3/VC-002 Mt Donna Buang 2014

Im in the middle of painting my house, and its taking a very long time, my only aspiration in life, be rich enough to pay someone else to paint for me, as such most weekends recently have been spent sanding, prepping, painting, swearing, re sanding, re painting, as i work through the house, both inside…

Mystical Unicorn DX Wire Ultra Light..

 A couple of years ago one of the Manly Warringah Radio Club members acquired some mystical unicorn DXwire from Germany. This created a heated debate that lasted for months on the merits of this expensive unicorn blood rainbow wire vs cheap and nasty copper from discount electrical suppliers R us. Well, i have just acquired some…
