We need more sunspots!

Conditions on 17 meters are bad today. I pulled out my 6 inch reflector telescope to do some troubleshooting on ol' sol. Yea, just as I thought: one measly sunspot. Confirmed by the SOHO image above.
There was a discussion on QRP-L recently about historical solar flux data. I started wondering what the SFI was on the day I was born. A few clicks with google brought the answer: On September 14, 1958 SFI was close to 300. Today it was 94. :-(

Something should be done about this! Write to your Congressman! Demand more solar activity!

Ponderosa Knack! Bonanza Astronomy!

I loved this episode, and I think most of you guys will too. I was alerted to it by an article by famed comet hunter David Levy. Wow! I never would have thought that in a 1962 episode of the cowboy show Bonanza, we would find amateur astronomy and experiments to determine the speed of sound and the speed of light. Amazing. There is no radio in this so it is not really The Knack, but young Mr. Michelson (yes, the Nobel Prize winner) does set up a shack-like workshop and he is trying to measure c. So this is all very Knack-like. There is also a very nice moral to this story, a moral that is related to our notion of an International Brotherhood of Electrical Wizards.
Three cheers for Ben Cartwright!

You can find the episode here. It runs for 48 minutes:

EE Web Featured Engineer: Alan Wolke, W2AEW

I really liked this interview with our friend Alan. You can see definite signs of an early case of The Knack here: I was especially impressed by the fact that he made one of his first antennas from wire salvaged from the deflection coil on an old TV. (I took the easy path and chopped up my dad's extension cords!)

I also liked Alan's response to the question about his favorite software tool: "Gee, solder is soft, can we consider that software? I use a lot of that!" This is very reminiscent of a quote from the legendary Bob Pease (colleague of Jim Williams): "My favorite programming language is solder." (That quote was sent to me by Steve WA0PWK. Thanks Steve.)

Lots of good troubleshooting wisdom in this interview, and Alan's enthusiasm for electronics clearly shines through:

"An Analog Life" A Video Tribute to Jim Williams



Yi Yao alerted us to this. Don't miss this one!

Yi Yao has The Knack!

Hi Bill,

I discovered SolderSmoke a few years ago by listening to another pod
cast. Ever since, I have been hooked on this podcast and listen to it
whenever I have time. I have finally caught up and finished episode
142 today. I love the enthusiasm and spirit of discovery and creation
that goes into the stories in SS.

The first time I heard about amateur radio was in high school. It
seemed to be a overly nerdy thing at the time and I wasn't sure what
it was. However, after I started listening to SS, I discovered that
this is something that I wanted to do. So, on New Years Eve with the
kind help of a local examiner (Ori, VA3XW), I wrote my basic and
advanced exam and passed with honours. In Canada, we only have 3
categories: basic, advanced and morse co
de. I am very excited about
this and I am glad that SS made me make the jump.

You know, every time the word knack comes up, it is portrayed in a
negative way. Someone is "afflicted" with the knack or shows knackish
"symptoms" as if it was a horrible disease. I would like to change
this perspective.

I hereby declare myself blessed with the knack. Ever since I was a kid,
I disassembled various electronics around the house (to the dismay of
my parents). I knew when I was doing something right when I could put
something back together and it worked, or later, it worked better than
before. Despite my parents' persuasion to pursue other branches of
non-technical studies, I made up my mind to study electrical
engineering (must have been a teenage rebellion thing). Nonetheless
I finished school and found a job doing electronics design which I
love. Some of the people that you meet in this field are just
phenomenal. It has been a good career decision and I think it is truly
amazing. Thus, I see the knack as being a gift which I was fortunate
enough to hold.

I think one of the most important aspect of the knack is the desire to
understand and have self reliance on what we use on a daily basis. I
repair my own bikes and I've never bought a ready made computer.
Having a home machine shop greatly helps in this regard too. My first
oscilloscope I designed and built myself:
http://yyao.ca/projects/oscilloscope/
I have also resolved to build my first rig instead of buying one.
However, work is really busy these days, and it doesn't look like I
will be able to do this soon. One of these days, I will construct my
own rig and wiggle the ether.

I am currently visiting Silicon Valley here in California. There is
much to visit and do here. For example, the De Anza Flea Market
happens every 2nd Saturday (which is my first introduction to a swap
meet):
http://www.electronicsfleamarket.com/

The Computer History Museum is amazing:
http://www.computerhistory.org/

For a limited time, you can see Jim William's work bench at the
museum. If you thought your workbench was messy, you haven't seen
anything:

Now, imagine having the world's most smartest electronics engineers
having dinner together. That's what the Analog Aficionados Party is about:
http://www.edn.com/blog/Anablog/41523-Analog_Aficionados_party_Feb_18_2012.php

On top of that, there are a lot of trade shows which you can go to
check out the latest and greatest of test equipment. They don't have
the same feel as some of my analog oscilloscopes, but they are shiny.
As you can see, this is a paradise for anyone blessed with the knack.

Anyhow, this email is long enough and I hope your eyes haven't glazed
over yet. My best regards to you, Billy, Maria and your wife.

73,
Yi Yao

Workbench Upgrade

Lots of good ideas in Todd's video. I need to do a lot of this kind of improvement.

Google CW!

Google announced this yesterday. VERY timely. I wish I had thought of this!
