I started in radio and electronics in the Spring of 1961, while in the 8th grade, when my father helped me build an AM crystal radio set. It used a coil form my grandfather had used in his home-built crystal set and a cat's whisker detector which contacted a galena (lead sulfide) polycrystal.

In high school, under the mentorship of a neighbor, Jack Zizan, who was in technical school to become an electronic technician, I learned Ohm's Law, and built a vacuum tube, short wave, regenerative receiver, a vacuum tube, 2 meter superregenerative receiver, a three vacuum tube audio amplifier (35W4, 50C5, 12AT6 vacuum tubes), a vacuum tube AM transmitter (using a single 6BG6 tube), transistor multivibrator, and a transistorized metal detector and a vacuum tube, 1" oscilloscope (using a 6SN7 tube, a 1", 913 CRT, and a NE-2 neon bulb relaxation oscillator). Jack also taught me about vacuum tubes, diodes, triodes, tetrodes, and pentodes as well as PNP and NPN bipolar transistors (2N107, 2N170, CK722, CK768, etc.). I was also an avid short wave listener (SWL) using, at first, the regenerative receiver and eventually, a Hallicrafters SX-110 communications receiver. I subscribed to Popular Electronics magazine (PE) and signed up for PE's SWL club. My Popular Electronics SWL call sign was WPE3DPA. I remember learning about HF ionospheric propagation and receiving QSL cards from the VOA, BBC, HCJB, Deutsche Welle, RAI, Radio Sweden, Radio Moscow, Radio Sofia, Radio Switzerland, Radio Nederlands (in Bonaire), and others. I was very well prepared to enter the electrical engineering program at Carnegie-Mellon University in September 1965.

Now I am a retired research electrical engineer whose former employers included: MIT Lincoln Laboratory 1975 to 2012, CBS Laboratories 1973 to 1975, Officer (Captain), US Army Signal Corps 1969 to 1977 (ready reserve). I am a graduate of Carnegie Mellon University's electrical engineering department with a BS in Electrical Engineering 1969, an MS in Electrical Engineering, 1970, and a Ph.D. in Electrical Engineering 1974. My research specialties include: Electro-optics, including laser communications, coherent and direct detection laser radar, infrared and visible imaging systems, microwave and millimeter wave radar systems and millimeter wave spread spectrum communication systems. I have also performed systems engineering and modeling using Matlab and MathCAD.

I am married and have seven children, who are all married, and we have twelve grandchildren.
