Past Meeting Info is here.
Feb 8 - Impedance Matching Part 2
Last month we did an intro with the basics, and answered
the question "why?", this month we'll get into more of the details of how with Smith
Charts and S-parameters.
I hope we can talk more about a project, those are always fun.
There was a lot of interest expressed, in the discussion at the end of the meeting, to get
people set up with a way to tune their antennas, from 137 KHz to 450 MHz. Since there are
several kits available to do this, and I'm building one of the better ones right now, I'll
do some research into the options available. Or maybe we can do our own. A good processor
with a color display is now about $20, that would be a good place to start.
Hope to see you all again at Tech Night. Bring a friend.
March 8 - TBD
Maybe we'll get a project going by then.
April 12 - TBD
Suggestions and requests welcome

Questions on the program, small specialty groups, time with test equipment
You should try LINUX
I didn't like windoze 10, so I took the
dive. It was very easy. I have not gone back.
The Fourier Transform
The one piece of somewhat complicated math
that does amazing things for radio. See it work, step-by-step.
What are all those beautiful radios in the
lobby at TechNight? Who owns those? Meet the man himself, who also happens
to be the owner of the building we're using.
Not just being active in radio, this is the
real thing. You'll see some real sources and how
strong they are with a geiger counter. "And they used to put those paint
brushes in their mouths to get them wet..."
Computers, yesterday and today
What it was like when I graduated from
college in 1978, and what it is now.
Computers, Part 2. Let's program
It's easy to do this. Just have to decide
what you want to do.
You want to try Moonbounce?
What it takes to bounce a signal off the
moon and hear your own echoes. You can measure the distance to the moon
yourself, no need to believe all this Wikipedia orbit stuff.
Intro to Music - where'd the scale we use come from?
12 notes make up an octave, but why 12?
Can you tune a guitar? Dan brings his keyboard to TechNight, the one with
88 keys on it.
Displays-they are part of everything
CRT, LED, VFD, LCD, TFT, OLED, DLP - all
explained. Ever want to hit your LCD with a
hammer? I did it, and I'll bring in the pieces with a microscope. Well run
a CRT at the meeting, and hold magnets near it.
Like displays, you need to see the output, but
used to be hard copy. I'll bring in some rather unique
types of printers and show you how they work. I paid my way through college
All about the man and what he did and didn't do.
There are a few other people we should do, too.
Minicircuits, the company
For an RF engineer, this is heaven. A look through their catalog,
and the new XMicrowave building block system.
If you want to do your own topic, or suggest one, feel free to talk to Dan.
