Read moreAs of last weekend the long awaited link between Mt. Wombat UHF repeater and Mt. Big Ben UHF repeater is up and running. Thanks to the efforts of Peter Mills of Amateur Radio Victoria. The Mt. Wombat end is 438.650 – 7.000 Mhz split and 91.5 CTCSS Mt. Big Ben end is 438.925 – 7.000 Mhz split and 91.5 CTCSS

Read moreOn the 16th July 2023 VK2EXA Greg made contact with VK3YE Peter who’s POTA park station was at Seaford Wetlands Reserve out of Melbourne. The contact was made at Peter’s end from his Solderless Breadboard ATU. The video is about 27 minutes in duration.

Read moreThe club’s old portable repeater developed an intermittent problem so we’ve decided to replace it using slightly more modern technology. After a generous and appreciated donation by VK3TIM of the key parts for our new repeater, the new system is almost complete.
Read moreMichael Harvey VK2JMJ December 2021 Theory: Antennas are basically a resonant element in the sky. That resonance can be obtained by a natural RF length or wavelength of wire. That length can be physically shortened or made to look longer at RF by adding inductance in that length. A combination of inductance and capacitance makes the element resonate. Read the […]
Read moreAnother successful Antenna Project from Rob!I want to share with my fellow Ham guys another successful antenna build for 70 cm the VSWR is less than 1.3:1. The only thing for me to do now is to polish the brass construction and coated and a clear sealant most pleased I am. I also wish to add everything except for the […]
Read moreWell this is my latest creation with help from Ross VK2DGY and Lloyd VK2KNS. The rod is an old fishing rod with all the fishing bits and pieces chucked off. Everything is been made by hand the only thing now to do is to check it for tuning. I must say that’s the scary part. It will work or it […]
Read more80M transmission dropping out the NBN by VK2JMJ, Albury. August 2021. Michael HarveyThe situation: I use a fibre to the node type NBN service, (ie: old twisted cable pair from the house to the node at the green box, just down the street) with a speed test result ranging from… download full PDF article here>
Read moreUpdate! As you can see I’ve done some fancy work to my halo antenna as it’s now blue. There is also a photo of the metre showing how well it has been tuned with the help of the boys at the club meeting. Very much appreciated. Rob VK2MGM Some photos of Rob VK2MGM tuning his new Halo Antenna for 2 […]
Read moreLightning protection has been moved from inside the container to an ideal “bulkhead” installation. Several reasons – this gets the cable entry on the other side of the mast where we don’t have to avoid it while raising or lowering the mast, it gives us about 500 mm or so more slack to raise the mast a little further, and […]
Read moreA fun little project I did over a couple of days was making this little 6 element yagi for 70cm. There are so many designs and ways one can do this so after some reading of different designsand measurements I came up with this (photos below). I decided to go for a dipole driven element fed by a “Bazooka Balun”. […]
