[Alexandria Radio Club Reflector] Invitation to Alexandria Radio Club Monthly Meeting via Zoom on Friday, December 11th

[K3EUI at AOL]

Thank you all for inviting me to speak at your Club meeting last night, 
Dec 11th.

It was a joy to learn about this NANO VNA gadget, and then share what I 
knew (or thought I knew) with others.

I've only had mine now for a few months. It was a gift from a local friend.

I got thru about 1/2 of the slides I had prepared, and can send a more 
recent� pdf of the entire presentation as an attachment.

If anyone has questions or comments, write to me directly:

 ���� k3euibarry� at� gmail.com

There are many youtube videos out there now on the NanoVNA, some good, 
some poor.

Check out� W2AEW� Alan's� videos... they are superb.
