KI7TU's Reference Page - About Me

Here's a "selfie" taken on 26-Jan-2015 with my "FLiR" (thermal imaging) camera: False color image of the author

Briefly, I'm Clark Jones, and hold Amateur Radio callsign KI7TU, an "Extra Class" license. Although I first got interested in electronics in the mid 1960s, I didn't get my first Ham license until 1991. I also hold a General Class Radiotelephone License (formerly a First Class Radiotelephone License) which I earned in the 1970s.

I earned an engineering degree in 1980, and then I worked for 23 years in the semiconductor industry, in a position where I did mostly software (writing highly specialized compilers) but had to be intensely aware of the electronics. The first two years were with a company that made "computer chips", and then 21 years with a company that made testers for computer chips. (I sometimes describe them as "multi million dollar volt meters", which is a fairly accurate description.)

For 20 months, starting February 1, 2012, I worked for a small start-up company called Serious Integrated Inc. which makes "Human Interface Modules", basically LCD Touch-screen modules with small embedded computers behind them, as well as related software. The combined hardware/software package reduces the effort to produce a working LCD with touch-screen from several man-years to a few man-weeks for businesses wanting to add such to their products. Officially, my title was Principal Design Engineer, though I did everything from working on specs to slapping the FedEx label onto boxes of product to go to customers.

My work experience also includes a little over a year working as an electronics technician in an electronics factory in the mid 1970s, working for about 8 months as a broadcast engineer at a television station in the late 1970s. (I left each of these two jobs to devote more time to my college education.)

I've been "tinkering" with computers since a few weeks after Niel Armstrong took his "one small step" onto the Moon in 1969.

Although I am into ham radio, I'm more interested in the technical, and to some extent, organizational areas than actually talking on the radio. Most of my talking on the radio comes on Field Day -- officially a demonstration of emergency preparedness -- where the group I go with drags the radios up into the mountains and sees how many other stations we can contact in a specified 24 hour period.

One of the things that has greatly influenced my life is my physical handicap - osteogenesis imperfecta ("brittle bone disease"). Between the ages of 2 and 15 I had approximately 45 broken legs, and was unable to walk until age 15. My earliest recollection of getting interested in electronics was in the mid-1960s when, while in the hospital, I got ahold of a magazine on electronics (probably Popular Electronics, though I don't recall for sure).

Besides electronics and ham radio, I have a fairly long list of other interests (though some are more "historic" than current) including (but not limited to):


I'm an active member of the Arizona Repeater Association, and amongst other things I serve as their representitive to the Amateur Radio Council of Arizona. I'm a fairly active member of MARCA (formerly called "Motorola Amateur Radio Club of Arizona", but because almost none of the current members of MARCA work for Motorola, the name was just changed to "MARCA"). I am a member of the American Radio Relay League (ARRL), which is the national club for Hams.

Outside of electronics and ham radio, I'm a very active member of Mensa, the "High-IQ" society. I'm also a member of the National Muzzle Loading Rifle Association.

Professionally, I'm a member of the IEEE.(Institute of Electrical and Electronic Engineers), as well as the IEEE Computer Society.
