VK3BQ*™ Cliptastic-Tenna Review.

Earlier in the year, Icom released the IC-7300, an SDR based Ham Radio, it was the first of the big three commercial ham radio manufactures to provide an all in one desktop SDR based device. This caused a bit of a stir in the worldwide ham community, A lot of people were keen enough in…

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/VC-031 Arthurs Seat 2015

Australia Day offers the opportunity to use a special callsign, Australian hams are allowed to use the prefix AX instead of VK on a handful of days throughout the year. I had to be in and around Melbourne this Australia day weekend with work commitments but had tentatively talked the family into a trip to…

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…

Case for SARK-110

Ive been looking for a bag or case for the SARK-110 for months. I had a look at point and shoot camera bags/cases, but they were all too small for the added bits or too bulky for what I had/wanted. The other week, a ham posted a photo of his case he had found at…

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…

Fixing a Radio Noisy Prado 150 Diesel

The trouble with operating from a car is, modern cars with electronic systems can be RF noisy! The diesel D4D engine in my Prado 150 series is no exception. With many sources of noise on the HF bands. From throttle noise to electronic injector noise, and base car background noise. Operating on some parts of…

Codan 9350’s are not indestructible

When Chrisitne got her new truck (4wd) I was keen to install some HF radio gear into it, i realised a codan 9350 auto tune antenna would be a nice addition, I had previously used a terlin tapped whip, and while this was a good performer, it was a pain to change bands when mobile!…
