AREG is pleased to announce that our guest speaker for our October meeting is Roger Harrison, VK2ZRH. The topic is “Ionospheric Propagation on 50MHz”.

For Adelaide based members the meeting will be held from our club rooms in Fulham Community Centre, Phelps Ct, Fulham, with Roger presenting from his home in Queensland. For remote members, it will be also available via Zoom where you can interact with the meeting. For non members, you can view the presentation via the HamRadioDX YouTube channel.

Start time is 7.45pm ACDT

(8.15pm AEDT, 7.15pm AEST, 6.45pm ACST, 5.15pm AWST, 0915 UTC)

It’s called “the magic band”. Propagation of 50MHz signals over long distances is supported by serendipitous opportunities that arise in the ionosphere, in both the E and F regions. Those opportunities may be anticipated, but cannot be reliably forecast. You’ve gotta be there when they happen! Then, it’s magic.

Roger will be covering the characteristics of ionospheric sporadic-E propagation (Es), transequatorial .propagation (TEP), and ionospheric F2 propagation. He has extensive experience in this area having previously worked for the IPS Space Weather Services Research / Engineering branch.
