In case you didn't know ...
There's an on-line virtual ham radio expo this weekend with a long list of topics. Lots on antennas, propagation, vector network analyzers, digital modes, etc.
The early bird cost is $10.00 and you can view the presentations up to April 10th. But viewing during the actual presentation times gives you the opportunity to ask questions.
Expo Hours:
Opens : March 11th, 1800 PST, or March 12th, 0200 UTC
Presentations Begin: Saturday, March 12th, 0800 PST,
or 1600 UTC
Sunday, March 13th, 0800 PDT,
or 1500 UTC
The Expo platform will remain open until April 10th, 2022 for on demand presentations.
Tickets are $10.00 until Expo opens, then $13.50 until April 10th
I have no connection with the organizers. Just wanted to get the word out.
