Left: The VK3AFW antenna system is
back in operation. Not quite all bands
but there is a 40/80 m trap dipole – one
trap can be see as the white cylinder at
bottom left—a triband 4 element 20/15/10
m beam, a 5 element 6 m beam, a 15 element 2 m beam, a 16 element 70 cm
beam and a 33 element 1296 MHz Beam.
A 2/70 vertical sits atop of the mast.
The tower is in its lowered condition and
only gets cranked up to the full 12 m in
calm weather.

THE EDITORS DESK - Ron VK3AFW
Welcome to 2015.
I have had a number of significant distractions that
have kept me off the bands for a month, not just because the antennas
were under rebuild.
I hope Christmas New Year was good for you. One member seems to
have acquired a new rig, I wonder if any of the rest of you got something
special too. Why not tell us about it?
I’m always looking for photos of club members and stories on your activities. Your help will be appreciated.
Congratulations to Kaye Wright VK3FKDW who has volunteered to take
on the role of Secretary for the AR publication Committee.
She and Noel VK3BMJ our publicity officer will publicize the Club IF you can give them some
input. I can’t emphasize enough how important this is. Without publicity we will not grow.
I look forward to receiving some interesting material in the coming year from you the Club member. And remember if something is too small on your screen use the zoom control.
73,
Ron, VK3AFW

CHRISTMAS PARTY 2014
This year we had a change in the menu and judging by the reaction of the hungry hordes it was
well appreciated. The photos are not quite up to standard—a mobile phone does not perform
well when hand held under low light. Can you name everybody in the pics?

EU VISITOR
Peter DL8FBT (left) has visited the Club several
times in January. He travelled to Australia on a
cargo ship and is staying with a friend In NarreWarren South. His home QTH is North East of
Frankfurt. His preferred mode is CW but he did
come with a hand held dual band FM radio.
Welcome Peter.

ANTENNA REBUILD
Following damage to the antenna array Ron VK3AFW has rebuilt and refurbished it over the
NY period. Above is the bent 40 mm mast that was replaced with a 50 mm mast. The replacement is the same length—above is the offcut from the 6.5 m length purchased from Robot Trading.in Clayton.

ANTENNA REBUILD CONT’D
The rebuild included:

Replacement stronger mast.

New coax for all antennas, including heliax for 1,296 MHz and foam dielectric for 2 m and
70 cm.

New dipole and reflector for 2 m beam—aluminium instead of copper.

New baluns for 2 m and 70 cm beams—see the 70 cm one under construction below.

Stainless steel hardware where possible, rust resistant paint on plated components.

AERIALS AND STUFF
PORTABLE TRANSMITTING LOOP
Left we see Brian VK3MCD with his home brew HF
transmitting loop. As is done with most of these a
standard 2 gang capacitor is used to resonate the
RG213 coax loop. The difference here is that a second variable capacitor is used to match to 50 ohms.
The loop is supported by electrical conduit as the loop
is not self supporting.
It is easily disassembled for putting in a pack. 40 m
tuners well on this one. The outer screen of the coax
forms the loop conductor.
While not as effective as a dipole it is quick to deploy
and occupies a much smaller space than the wire on a
squid pole so common these days.

AERIALS AND STUFF CONT’D
The basic schematic is shown on the
right. For QRP levels standard broadcast receiver two gang capacitors can be
used—250 to 300 pF max is enough.
Different sized loops can be used for different frequency ranges but a 2:1 range
is probably the limit to achieve reasonable efficiency.

SOTA LADDERS
While SOTA is not a competition, most involved like to see how they are
progressing toward their goals and how others are going. The Club has
four active SOTA enthusiasts at present.
Congratulations to Tony VK3CAT who has achieved Super Sloth Status as a Chaser.
All four activators have progressed with Brian nearly a Mountain Goat.
The points can change daily so check SOTAWATCH for the current listings.
