Online Amateur Radio Community Events
Welcome to the Online Amateur Radio Community!
There are two ways you can enjoy our events. Members can take part in events on Zoom. Visitors are welcome to watch our YouTube LiveStream and comment in the chat. Although we monitor chat, please note live streams have about a minute delay.
Our community is free to join, and is built on the community platform Discord. We offer a club without a committee, built and run by its members for its members. Rooms are open 24/7, we have specialist chat, training at all levels, and we are associated with the RSGB & provide their Brickworks scheme.
We host regular events, both social and structured on Zoom.
While we know that using a new platform like Discord can take some time to learn, we believe what we have is well worth it. We hope, by providing our events on YouTube, you can get a taste of what our community is all about.

Monthly talks are BACK at OARC! (For as long as 2M0IIG can keep it going...)
Title: An Introduction to Moonbounce
Start: 3rd January 2026 19:00 UTC
Description
Presenter: Jonathan Naylor G4KLX
At the extreme end of the hobby is Moonbounce, sometimes called EME for Earth-Moon-Earth. This is where every decibel matters and where DX flows even when the sun isn't jiggling the ionosphere. This presentation will explain the basics, and how we get over the path loss that occurs in transmissions that have to cover 750,000 kms and still be heard.
Future Events
| Date | Presenter | Title | Description |
|---|---|---|---|
| 7th Feb 2026 | Tom Wardill M9TWM | Beginning 3D Printing for Radio | Covering the basic of 'What is 3D printing?', 'What types of materials can I print?', 'What should I buy?', and 'Just how safe is this anyway?', Tom will cover a primer on the topic and hopefully inspire you to investigate why 3D printing is a perfect complement to your radio hobby. |
| 7th Mar 2026 | Derek Kozel | Beyond SWR: A Hands-On Introduction to VNAs, Impedance, and TDR | A Vector Network Analyzer lets you measure why a radio system behaves the way it does. This talk introduces vector network analysis through the problems you actually face at the bench and in the shack: locating discontinuities in coax, reading an antenna’s feedpoint impedance as a complex quantity, seeing what a matching network changes across frequency, and verifying filter performance with two-port measurements. Using a NanoVNA with NanoVNA-Saver and short Python examples, we’ll connect live measurements and saved S1P/S2P files to the underlying ideas - reflection, transmission, calibration, and time-domain transforms - so you leave with a repeatable workflow for making trustworthy RF measurements, including a practical look at small-signal measurements of a amplifier. |
| 4th Apr 2026 | Mark Pentler 2M0IIG | An overview of aviation RF emissions | |
| 2nd May 2026 | Ian Renton M0TRT | Everything on the Air: An Introduction to Operating in the Great Outdoors | If you're curious about getting started in portable operation, how to go about it, where to go, or even why you should try it at all, this talk is for you. Ian only got started working portable in 2024, but quickly caught the bug, and 100-or-so park activations later, he'll share what he's learned about rigs, antennas, batteries, and operating techniques. From tough mountain climbs to the park down the road, and even just operating from your car, portable operating has something for every level of fitness and appetite for adventure! |
| 6th Jun 2026 | Everyone! | Flash Talks | A night of short talks and show-and-tells! Ten minute talks to showcase your work, tell some stories, or anything you want! Ping Mark 2M0IIG to sign up. |
