Ham Member Lookups: 5497

 

I became interested in radio when I was 10 years old in the fifth grade, building crystal sets and later DXing the BC band. I was originally licensed in New Jersey as KN2KDZ and K2KDZ in 1954. I got my first class phone license at the same time. Did weekend work at the transmitter of WAEB Allentown, PA while in college. Begining in 1956 I spent several summers working at WEVD, WMCA and WPAT all in the New York City area as vacation relief man. My ham interest has primarily been in the VHF and UHF bands, first with 2 meter AM. 432 MHz AM/CW was added in 1959. I moved to Florida in 1962 to work for RCA on the space program initially in telemetry and eventually CW radar. I was sent down range to the Bahamas and the West Indian islands of St Lucia, Antigua and Trinidad. Supported all DOD launches. Still working for RCA I went to sea for two years on the Air Force ship Rose Knot in support of the Mercury and Gemini programs. Also worked at the Mecury/Gemini Mission Control before it was moved to Houston. Met all of the original seven astronauts and many other intersting people as a result. Later worked in Satellite communications for Harris and several other companies, visiting more than 40 countries worldwide on five continents. I became WA4GHK when I relocated to Florida. 220 MHz was added at that time followed by 1296 MHz in 1963. Both bands were AM/CW. Still later, everything was changed to SSB operation with much improved results. Operation was begun on 10 GHz in 1980 with phase locked gunplexers operating in NBFM and CW (FSK) modes. With these, WD4NGG and I held the North American DX record for 10 GHz for several years in the early '80s by working 300 miles between Hilton Head Island, SC and Melbourne Beach, FL. I am no longer on 220 MHz. 2304 MHz was added in 2001. In the last few years have added the 3456, 24I92, and 47088 bands. I am building for 80 GHz.. I am also active on 160 meters with a tee antenna 47 feet high, the flat top section of which consists of 3 parallel wires 100 feet long spaced 3 feet apart. A buried radial system is employed having 25 radials 50 feet long. This is driven with 1500 watts and has proven to be a much more effective system than I ever expected it to be. I have held an extra class license as NN4AA since March of 2002        The first picture above is my 160 meter T antenna. The three wire flat top is clearly visible, while the vertical downlead is not so obvious. The second picture is of my shack. The third shows my 10 GHz portable station attempting a DX contact on the beach. Dish is 4 feet in diameter. The fourth shows me at the operating position. Note several vintage recievers and home built BC set built when I was 14, and test equipment stack on the left. Last, my VHF, UHF and microwave antennas. From bottom in the picture, 2 meters, 3456 MHz, 2304 MHz, 1296 MHz and on top, 432 MHz. A common 1/2 inch hardline feedline is used with a remote relay in the box at center.
