11-March-2017 Contest: RSBB Commonwealth Contest
Safely home now after making little over 150 QSOs in the Commonwealth contest (the exact figure is now 169). Very poor showing on my and the propagation part. Last year I’ve made over 350 contacts. This year only half of that number. This time the band openings were shorter, but the signals when there was propagation were big. Typical […]

Professor Pask, in addition to her research work, maintains a full academic life and lectures at Macquarie University. Andrew Howie is a member of our club and a good mate of Jeff Keating.

Why authorities only worry about odd-order IMD?
Why is it that ACMA only worry about odd-order IMD when measuring? 3rd & 5th in particular? Why not the evens? Matt (25-Jan-2017): 2nd order IMD products (eg. f1+f2) will occur well away from your desired signal, and are easily knocked out by your bandpass filter. However, 3rd order IMD products (eg. 2*f1-f2) will fall very […]
January 2017 Lecture – ICOM 7300
Now I need to buy one! View the lecture on VK2MB-TV! The ICOM 7300 session/lecture was originally planned for the HF Month – March 2017 – however as the Wyong field day is at the end for February and many members wanted a reason to grab one at the field day, a lecture/review of the […]
Workbench Cam
The clubhouse is now equipped with a Workbench Cam! Remember these evenings where everyone crams around the table at the front of the hall to witness the opening an interesting box or the soldering iron trying to fix a broken device. And how about these lectures where the presented gear is on the table and […]
Terlin Antennas – getting SWR down
Dom (17-Jan-2017): Before heading off on a 2week trip to the (quite hot) Red Centre I was just doing a quick sweep of my HF antenna at lunchtime. Although I have a nice dip at 7060, it doesn’t go very low, about 1.65:1. This limits my BW on 40m a bit. Antenna Mounted on bullbar. Any […]
Phone chargers for the car!
Two recent camping road trips where we relied on the travel time to charge our 2 phones convinced me to build a linear 5v power supply. We use an AM Airband radio in the car that is very sensitive to RF from typical switch modes phone chargers. The IDLA charger we bought even overrides our car […]

25-Dec-2016 Xmas Net 0900 local (Sydney, Australia)
Ho ! Ho ! Ho ! Everyone, Another successful M.W.R.S. Christmas net this morning but unfortunately local signals were in the noise a little.

Nick VK2FS, Ian VK2ZIM and Geoff VK2AVR set up at the playing fields just behind our club location for some portable operating. 6m was open fairly early into VK3, and our […]
14-Nov-2016 Elanora Cubs
Elanora Cubs were our most recent guests, finishing up a very successful 2016 Scouting program for us. This group were particularly energetic and really enjoyed their visit, and it was great to finish the Scouting year on a positive note. Many of this troop were already familiar with the Phonetic alphabet so it was a great opportunity to […]
26-Oct-2016 Killarney Cubs’ vist 7-8:30pm
On Wednesday evening the 26-Oct-2016 we had Killarney Cubs visiting us – 16 all up. This is unusual for us for a Wednesday evening but good coincidence with freebee evening. The Cubs were full of beans as always, thanks for all the early helpers. And thank you for the nice campfire. (archived picture)
