-Enter the world of Aviation RF and discover the many and varied signals that aircraft emit. Learn about tracking planes over ADS-B, digging deeper into operations with ACARS reception, shooting for the niche world of satellite aviation comms, and - for the real nerds - the various navigation aids and other bleeps and bloops that help aircraft do their job.+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.

 | 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! | | 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.

 | 3rd Jan 2026 | Jonathan Naylor G4KLX | [[https://www.youtube.com/watch?v=fGBvl1gbK7g|An Introduction to Moonbounce]] | 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. | | 3rd Jan 2026 | Jonathan Naylor G4KLX | [[https://www.youtube.com/watch?v=fGBvl1gbK7g|An Introduction to Moonbounce]] | At the extreme end of the hobby is Moonbounce, sometimes called EME for Earth-Moon-Earth.
