Welcome to Fall,
Gordon’s “Ratio” post ,
Elmer Night Big Top,
Jamboree-on-the-Air (ARRL Letter),
and all the usual stuff!
“Read all about it” below.
Some of you know what AD5GG, Gordon, does for a living.
For those of you who do not, he designs antennas.
Note: Gordon tells me that
“I’m not really an antenna designer. Well, I mean, I do. But it’s not the bulk of my work.
I’m an RF hardware design engineer. But hey. Antenna designer sounds more exotic!”
Gordo had a great blog post this week that you REALLY should go read! Here are a few teasers:
The RF world is full of esoteric terminology, and not least of these is characteristic impedance, or Z0. Most coaxial cables have a characteristic impedance of 50 or 75 ohms. If you want to know why 50 ohms was arrived at as a sort of standard for radio applications, you can read this post. In the simplest terms, the characteristic impedance is calculated by the formula on the right, taking the square root of the distributed inductance (nH per meter, for example) divided by the distributed capacitance (pF per meter, for example).
Still interested? Here’s more:
Properly defined, the characteristic impedance is:
The ratio of the amplitudes of the voltage and current of a single wave, propagating down the line.
A single wave meaning a wave traveling in one direction, with no reflected waves or other anomalies.
What’s in a name? Co-axial means that both conductors in the cable share the same axis, i.e: if you cut a piece of coaxial cable and look at the cut end, the radius of the both inner and outer conductors can be measured from the center line of the inner conductor.
I hope that you are hooked! Here’s the link to the entire read, and be sure to read it to The Very Latest Sentence!
Elmer Night CROWD
The long awaited “Elmer Nights” began this week.
And THEY HAD A CROWD! There were at least 30 people there for the first night.
There were a number of pictures posted to the SCAR Facebook page,
but here is a small montage:
I’m told that some “Old Dogs” learned “New Tricks”!

Jim Harvey, KF5NRW, sent me this request via email earlier this week. If you can help, send me an email at email@example.com and I’ll share his email with you.
I have a bit of an off-the-wall question. I am a previous member, but due to health problems, retirement tasks, etc., I have been unable to attend the meetings or even to keep my membership up to date. I have an old Heathkit AR-1500 receiver that has a channel on the blink. I can’t find my original assembly manual for the AR-1500. I was hoping that you or some club member might help me by:
1. Allowing me to use and/or photocopy their AR-1500 assembly manual until I can locate mine.
2. Recommending a local supplier of electronic supplies and parts where I can buy some Deoxit or other contact cleaners. Sending off to Mouser or Digi-Key is such a pain.
3. Suggesting any other club members who are into audio electronics.
It’s not Ham, I know, but I have got to figure out a way to ease back in while solving my other electronics problems. Thanks.
Jim Harvey, KF5NRW
