Hi all
I ran across a Bell Lab video on SWR. He shows a mechanical analog to
describe transmission line. I recommend viewing to your students. In a few
minutes he describes what it took me months to understand.

Thanks Domenico
for the reply. You are correct the physical temperature and the equivalent
noise temperature are not related. Bob wb4apr suggested that a 1/4 wave
antenna in LEO has a noise equivalent temperature of ~ 150 k . What is the
consensus of the group ? We are trying to do an uplink
Hi,
The BATC team will be there and will be making recordings of the
presentations. At the present time we are uncertain about live streaming as
we are uncertain about the quality of the hotels internet access. If its

Thank you for the link. I have read JFK's speech before, but never seen the
delivery. A great man.
I was 8 years old when he was murdered. I was making Christmas decorations with
my mother in the kitchen, we had no money for decorations so we were cutting
out silver stars from the foil tops
Hi Jim,
I am sure I am expressing the views of the many who would dearly like to attend
but can't due to personal circumstances.
The live stream is a great way for us to have some involvement, the emphasis
being on live.
Of course the recorded stream will be welcome but
Nick,
Thanks for sharing! Very cool video. I have never seen wave theory demonstrated
with such clarity.
