Is space weather and propagation a bit of a mystery to you?

Our February 2026 presentation night brings us Roger Harrison VK2ZRH who promises to enlighten us about Fe, f, foE, MUF – all that ionospheric stuff.

With decades of experience, including his time at the Ionospheric Prediction Service (IPS), now Space Weather Services, Roger brings significant expertise in this space (pun intended).

This presentation will unpack the mysteries behind ionograms, TEC maps, Es, GRAFEX, PCAs, solar indices and more, plus online tools and data sources you can use.

Whether you’re chasing DX, planning portable operations, experimenting with digital modes or trying to understand why your favourite band just vanished, this session may give you the skills to read the sky like a geek bro.

This session will be in person and streamed from 7:30pm in Queens Domain clubrooms.
