Amateur radio, also known as ham radio, is the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communication.

Moving above the VHF and UHF bands can be challenging. It’s fun though. There’s a whole new world of experimentation and hands-on. If you’re in an elevated position or like going portable, give this aspect of our hobby consideration.

There’s nothing better than heading out and making a few contacts on a field weekend either with the local radio club or flying solo, especially when 6m is open! My contests of choice – the John Moyle field day and the VHF/UHF field days.

WSJT-X and FT8

WSJT-X and FT8

If you’ve lost interest in the HF bands, why not give FT8 a go. It’s super easy to get going, and with an ever increasing range of software becoming available to assist in QSOs and logging, it leaves more time for making contacts!

First licence in 1981 as VK3XFQ, then VK3KIR, I'm now VK3FS.

Licenced UAV pilot

All good hobbies need a licence, and flying drones is no different! I'm CASA certified.

Well, it's a living

Since 1984 I've been in the broadcasting industry. Production in TV and on air on ABC Radio.

  • Working VHF DX is a lot of fun, but it can be challenging. I’ll show you the tools I use to work VHF from -20 to 40 over.

  • On the second of September 2020, ARISS announced that the setup and installation of the first element of our next generation amateur radio system had been completed and amateur radio operations are no

  • Melbourne's ATV Repeater VK3RTV has made a welcome return. It's found a new home on Mount View, right next to the Victorian Police Academy in the easter suburbs of Melbourne.

  • I recently came across Alan's (VK3DXE) post about The VHF/UHF DX Book. He reminded me about how much of an invaluable resource it is. It's now available online as a PDF.

How to track 2m Interference

Tracking VHF Interference

Whether it’s an annoying buzz or hum, radio interference can certainly diminish enjoyment of our hobby. Finding it and getting it fixed can be one of those challenges that can really try us, but it need not be. This is the story of my local QRM and how I fixed it.


Experimenting with microwave is not only a lot of fun, it can be a terrific learning experience. From 2.4GHz up, there’s so much to build and experiment with. The black boxes stop at 1296MHz, so transverters and sequencers are norm as you head up the spectrum.

Fixing the IC-9700 drift

The Icom IC-9700 is a brilliant radio with just one flaw. It drifts! If you’re just using the radio on voice, then chances are, you haven’t noticed. The frequency drift issue has had many talking about this instability since the radio’s release back in January 2019. For such an expensive transceiver, how could Icom have overlooked something as fundamental as frequency stability?
