Hello ham radio enthusiasts:

I wanted to let you know about a sneak preview screening happening at the Davies Auditorium on May 3, 2022 at 7:30 pm. The film INVISIBLE THREADS – From Wireless to War is about the early development of wireless technology and features Tesla, Marconi and a mysterious German wireless plant called Telefunken, which secretly aided the German military effort during WWI.

Ham radio expert Charles Apgar is also featured.

After the screening, filmmaker Joseph Sikorski (Tower to the People) will participate in a Q&A session.

Please feel free to spread this information to anyone you think might be interested.

I hope to see you there!

All the best,

Linda Lee
