 ===== Next Event =====
 ==== Monthly talks are BACK at OARC! (For as long as 2M0IIG can keep it going...) ====
-**Title:** An Introduction to Moonbounce\\
+**Title:** Beginning 3D Printing for Radio\\
-**Start:** 3rd January 2026 19:00 UTC
+**Start:** 7th February 2026 19:00 UTC
 ====Description====
-Presenter: Jonathan Naylor G4KLX
+Presenter: Tom Wardill M9TWM
-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.
+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 MW0LNA | 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 | 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.
