Due to social distancing because of the Coronavirus-19 threat, physical meetings are postponed for the time being. Because of this, we will hold trial meetings as radio nets.
The next WARG monthly meeting is to be held on air Monday 8 June 2020 on repeater VK6RLM (146.750), not at our regular venue. The meeting will commence at the regular time of 19:30 hours. Hope to hear a few people on the net.
If you wish to participate in the meeting, you can do so by the following: Radio: Repeater VK6RLM 146.750MHz -0.6Mhz offset ALLSTAR: Node 28608 Echolink: Node 909122

HARGfest 2020 has been cancelled due to the current health concerns. Hills Amateur Radio Group would like to apologise for any inconvenience this has caused and hopefully we can reschedule sometime in the future.
Tools Required. Hacksaw Mitre Box (to cut the pipe square) Electric Drill Drill bits Tape measure Crimp tool for fitting coaxial fittings. Soldering iron and solder. Knife Pliers Side cutters Wire strippers. Black marking pen White marking pen (for marking black coaxial cable)
Materials. 20mm White PVC Pipe (25mm outside diameter) 20mm end caps 20mm female coupler (sleeve joiner) Fishing line RG58 coaxial cable Coaxial fittings (either PL259, SO239, N male or N female) Each antenna requires a length of about 1200mm of PVC pipe to construct.
PVC pipe comes in 3 metre or 6 metre lengths and a number of classes that define its pressure rating (wall thickness). One 6 metre length allows the construction of 5 antennas with minimal wast of pipe.
The lowest pressure rating available would be suitable for pogo stick antennas.
Notes on Pogo
Stick Antennas.
The design by Will VK6UU suggests dipole segment lengths of
425mm each and choke coil of 9 turns on a 20mm PVC pipe (25mm OD).
Other suggestions are 440mm for the upper segment of the
dipole and 470 for the lower, or, 457 for the upper and 447 for the lower both
with a choke of 9 turns.
The 440mm/470mm antenna tunes in the 147MHz segment and the
457mm/447mm tunes in the 146MHz segment.
VK2ZOI suggests 450mm for the dipole lengths and 10.5 turns
on the choke, or 457mm for the dipole lengths and 9 turns on the choke.
In various designs, choke coil varies in number of turns
between 9 and 11.
In recent WARG designs, the PVC pipe has a PVC cap at the
top and a female PVC coupling at the bottom with a short attached section of
pipe to provide weather protection to the coaxial fitting (plug or socket).
The coaxial fitting is not mounted on the PVC pipe but is attached to a short pigtail of coaxial cable coming from the choke winding.
The next WARG meeting is to be held Monday 9 March 2020 at the 1st Pelican Point Sea Scout Group, 12 Australia II Drive Crawley. (Down the end past the yacht club) Doors open at 19:00 for a 19:30 start. Tea and coffee are available. All are welcome.
Steve, VK6FTOW Vice President of WARG would like to know if there are any questions pertaining to WARG general business, for people unable to attend the meeting? Please leave any questions in the comments section below.
Saturday 2nd May 2020, at the Bassendean Community Centre 48 Old Perth Road, Bassendean
WA Amateur Radio News is pleased to announce that we will present PerthTech in 2020.
PerthTech is a One Day Seminar with a wide variety of subjects presented by experts in their field.
Following the success of last year’s event, where entry was free, the committee has decided once again to provide PerthTech as a free event, as a service to Amateur Radio in Western Australia.
We will again get together for an evening meal at the pub afterwards. Order and pay for your own food and drinks.
Of course we can’t produce an event of this quality out of thin air, so we will be raising funds via a raffle. We are still looking for a suitable prize, and as soon as prizes are determined, we will launch the raffle.
Meanwhile, mark your calendar and set aside Saturday 2nd May 2020 for a day you must not miss.
Even though the event is free, we will take bookings online for entry. There will be a fee for lunch, and payment for this will be online at trybooking as well. You don’t need to sign up at trybooking, and you can pay with a Visa, Mastercard or Amex card.
There will be an incentive offered for booking online to avoid having to deal with a queue at the door.
