K9LA: “Solar Cycle 25, Space Weather, and Practical High Band HF Antennas” at Nashoba Valley ARC Meeting, May 20, 2021

Nashoba Valley ARC logoPhil Erickson, W1PJE, writes on the NVARC mailing list:

We’re pleased to announce that the May [20, 2021 Nashoba Valley Amateur Radio Club] meeting will feature Carl Luetzelschwab, K9LA, speaking on the topic “Cycle 25 Update and Understanding Space Weather”.  NVARC is very fortunate to have K9LA, who is in demand nationally and is a regular at Dayton Hamvention’s forum talks.  He also made presentations in 2021 both at K3LR’s Virtual Contest University and 4Z1UG’s QSO Today Virtual Expo.

Summary: Carl K9LA will discuss the predictions for and the progress of Solar Cycle 25, including what to expect in terms of propagation throughout 2021 and as Cycle 25 ascends. He will also review simple antennas for 15m, 12m and 10m as Cycle 25 ramps up. He will then briefly review websites with space weather data and how to tie this important data to HF propagation conditions. Finally, he will highlight real-time propagation websites that allow us to assess what’s happening right now.

Biography: Carl Luetzelschwab K9LA started his radio career as a short wave listener in the late 1950s. He received his Novice license (WN9AVT) in October 1961, and selected K9LA in 1977. Carl is a graduate of Purdue University and was an RF design engineer until his retirement in 2013. Carl enjoys propagation, DXing (he’s at the Top of the Honor Roll), contesting (he was NCJ Editor from 2002-2007), experimenting with antennas and restoring/using vintage equipment.

He and his wife Vicky AE9YL enjoy traveling, which has included DXpeditions to Syria (YK9A in 2001), to Market Reef (OJ0/AE9YL and OJ0/K9LA in 2002) and numerous trips to ZF (Vicky is ZF2YL and Carl is ZF2LA). Carl is currently the ARRL Central Division Vice Director. He has received the Bill Orr W6SAI Technical Writing Award, the YASME Foundation Excellence Award and the Indiana Radio Club Council Technical Excellence Award.

[W1PJE: Carl maintains an extensive website at https://k9la.us with selected articles and presentations about propagation and solar topics, grouped into categories – Monthly Feature, Timely Topics, Basic Concepts, Tutorials, General, 160m, HF, VHF and Contesting.  It’s well worth your time.]
