The Harry Angel Sprint is an annual 80m contest event, first established in 1999, to commemorate the life of Harry Angel VK4HA who at the time of his becoming a Silent Key was the oldest licensed amateur in Australia.

The duration of the contest is 106 minutes one minute for each year of Harry’s life. Continue reading


John Moyle Field Day Redux


The Field Day is over for another year but there was plenty of action around the bands –



From Broke NSW (near Singleton) VK4BZ put on a solo effort.


JMFD Operation by VK5ZT

JMFD operation by VK5ZT

For the first time ventured down south of Adelaide with the roving van for the JMFD.
It was a somewhat cobbled together effort as the van is in the midst of a makeover and update.
No huge antenna arrays, dishes, masts etc… just a setup that can park and be on air up to 24 GHz in less than ten minutes
and packed up even faster….

The site was a property owned by Barry VK5KBJ…ten acres on a hilltop with good views to the
north and west and generally good coverage in all directions. It is a popular site with southern Adelaide hams
and there were others nearby on site which was occasionally problematic, as one would expect!

In terms of operator numbers it was pretty quiet, especially for a VHF & Up operator. Signals from the city were fairly weak as there is
a bit of real estate in the way. There were other operators up north who provided regular contacts during the contest.
It was still the usual flurry of activity followed by periods of nothing…

Here’s a few happy snaps of the van on site…

Van setup on site…


Another view…

There’s a cable leading away from the tank whip antenna on the front of the van. This was to allow Dave temporary use of the whip as it was the best performing six metre antenna on site despite the length of cable involved!! The RF field can get a little troublesome with equipment in the van if 100 W is used….I don’t think the operator has been affectered affeeted affectte affec affe…………………….. :)

Here’s the contest operating desk…

Not too far away was Dave 5KK. Here’s a night view of his station….

Dave 5KK’s station

We had a late evening dash to a Maccas for food and COFFEE. The temperature was dropping fast at the site.
The 4 AM start to hit the overnight time slot was a bit erratic due to operator fatigue!
I think (the very few) other operators felt the same way! I crashed for a couple of hours when I got home
to try and recover from the lost sleep a bit!

How well we did remains to be seen but not too bad a day when all was said and done…maybe next year, maybe!






We had three generators running continuously for the JMFD. 2 Honda Eu20i and 1 Yamaha EF2400is.

Our ops on 80 mx had their dipole strung above and quite close to the generators with no noise issues.

no noise issues.

The trick is to manufacture outboard powerline filters that can plug directly into the output sockets of these generators. Unfortuntately C tick in Australia does not mean the same thing as it does in Europe, where it is mandatory to fit EMI filters to the internal casing of the generator.

We use good quality EMI filters preferably with two series inductances/capacitors and rated to the current rating of the generator and mounted in a suitable waterproof plastic box.

THE SECRET TO SUCCESS HOWEVER, IS TO ADD A SUITABLE INDUCTANCE TO THE EARTH LEAD AS WELL, since most EMI filters only filter the common mode and differential mode between the Active and Neutral. Unless of course you can find suitable EMI filters that are used in the medical field, where the earth lead is also filtered.

Attached is a suitable circuit setup, details of the earth filtering and a picture of one such layout. There are available suitable waterproof female power sockets that mount internally to the box. The connection to the generator is a short male plug on a flylead so that the box sits on the ground right next to the generator. The whole purpose of the design is to provide appropriate filtering without compromising the electrical integrity of the generator as required by the various standards that apply to portable generators.

Sydney Amateur Radio Ferry Contest

The Sydney Amateur Radio Ferry Contest takes place on Sydney Harbour on Sunday March 13th from 10:00 to 16:00 local time.

This unique new contest brings hams from all over the nation to Sydney Harbour and invites them to make VHF / UHF contacts from any of the system’s ferries and 36 wharves.

With all-day travel for just $2.50 using an Opal Card, this is a great way to spend a Sunday!

To add some fun, operation is restricted to hand-held radios (any mode) and can include repeater, simplex or “eyeball” (a handshake and an exchange of QSL cards) contacts. Continue reading


John Moyle Memorial Field Day 2016

Rather than tapping away on the internet, here is a very good opportunity to get on air. If you have a radio there should be no excuse.

I am thinking of entering the 8 hour section as I have a function on the Saturday night… de VK4TS

The next Field Day will be held over the weekend of the 19th-20th March 2016 and will run from UTC 0100 on the Saturday to 0059 on the Sunday.

Delay to Trans-Tasman 2015 results

The Trans Tasman results are being delayed owing to some problems with the WebSite.

We moved the TT to an environment that will allow public logs and cross checking.
These results have been completed and all programming is done, for that stage.

The website houses the log files and the claimed scores, and unfortunately we do not have a copy of the various logs.


This WebSite is being created for future running of the event and others by VKCC.


As shown all details including participants who did not enter a log are included.

The site caters for uploading of logs and cross checking as well as errors in copying serial numbers.

We hope to have the completed results issued shortly.
