Unfortunately, if you look at ham radio gear, we are in even worse shape than the consumer market. Heck, even the freaking microphone connectors are unique to each manufacturer.
Last week, I had lunch with an old friend, Bdale Garbee (KB0G). Bdale and I had both worked at HP for a number of years and we have been involved in some common ham radio clubs and activities. I followed the test and measurement path with Agilent Technologies when that company was formed, while Bdale stayed with the HP computer business. He is a recognized industry expert in Unix, Linux and all things open source. It is always cool to catch up with him and find out what he has been doing. He recently took early retirement from HP…I am not sure what “retirement” means for Bdale but its not playing shuffleboard at the retirement home!
Coincidentally, a few days later, I came across this video from HamRadioNow of Bdale talking at the ARRL/TAPR Digital Communications Conference. In this talk, Bdale discusses the general theme of making stuff and the satisfaction that is derived from that activity. It is about an hour long so grab a cup of your favorite beverage and take a seat.
By the way, check out the other HamRadioNow videos, especially the videos of the DCC technical talks. Good stuff!

I was writing an electronics article today and started to do some circuit analysis by hand. It was a pretty simple circuit so I knew I could crank out the circuit analysis on paper but I started to think maybe there was a better way. I poked around the web and came across CircuitLab.com, a free, online circuit simulator.
As I gave it a try, I was amazed at how easy it was to use. I just started doing some simple drag-and-drop from my browser and the circuit quickly took shape. A few minutes later, I had my first analysis running and I started playing “what if” games with the circuit parameters.
OK, I’ll admit that the circuit I created was pretty simple but still, I am impressed. Oh, and did I mention that its free? If you have need for circuit diagrams and simulation, check out CircuitLab.com.
