Have been interested in radio since grade school. Passed Novice exam on my 15th Birthday, 13 February 1959. However, the license was not issued by the FCC until 15 May 1959 and arrived as KN9STH. Passed the General exam in November of that year, while a sophomore in high school. Acquired "first phone" commercial license between senior year in high school and freshman year in college (1962).

First rig was a homebrew 6AG7 / 807 with hand wound r.f. chokes! Had 75 watts input and less than 10 watts output (most of the r.f. was going back into the power supply!). Soon graduated to a used Globe Chief 90A. Original receiver was a Hallicrafters S107 (replaced a Heathkit AR-3 that I used as an SWL - got another AR-3 a few years ago). Upgraded to a Hallicrafters S85 in 1960 and a Heathkit DX100. Then built a 22 tube homebrew receiver which included 6 and 2 meter converters, and built a home-brew 2 meter AM/CW transmitter. I used a slightly modified Heath DX-20 transmitter for 6-meters with a home-brew 6L6 push-pull modulator and the VFO section from an ARC/5 BC-459 transmitter for a VFO. Wrote my very first magazine article on the DX-20 conversion which was purchased by 73 Magazine in early 1961. The article was published in the October 1962 issue of 73.

Went to college at Georgia Tech in Atlanta, Georgia, where was employed by Motorola while in school and became interested in FM communications. Acquired 2nd station license of WA4MLI while in Atlanta. Came to Richardson, Texas, upon graduation in 1967, employed by Collins Radio (obtained another 2nd call sign of WA5STI - the FCC "kinda" upset me, missing STH by one letter, then became W5UOJ after the FCC did away with additional stations). Got my original call back in the mid 1990s when the vanity licensing program first started. Owned the Motorola Reconditioned Equipment facility for the south-central US for over 9 years until Motorola went out of that end of the business. During this time (early 1971) became the first FM Editor of CQ Magazine. Had first article ever written published by 73 Magazine in 1962 (putting Heath DX-20 on 6 meters). Have written over 1000 articles for 73, CQ, Ham Radio, Popular Electronics, other magazines, and newspapers.

Over the years I have gone through various rigs for all bands 160 meters through 432 MHz. Presently use "old" Collins S-Lines for 80 through 10 (including the WARC bands). Use a Heathkit SB-110A on 6 meter CW/SSB, Heath SB-301 / SB-401 into a Hallicrafters HA-2 transverter for 2 meter CW/SSB, and a home brew on 222 MHz. Use a Uniden HR-2510 as the "i.f." for a 432 MHz transverter and can run AM, FM, CW, and SSB. Recently constructed a "home brew" transverter for 160-meters that uses the Heath SB-301 / SB-401 as the i.f. Also built a single band linear amplifier for 160-meters using a pair of Russian GI-7bT triodes. Have several sets of VHF converters (50, 144, 222, 432 MHz) set up to use on different receivers. All of my antennas are located on the back "half" of a 72 foot wide by 130 foot deep suburban lot (fortunately 1/2 block from the highest point in the city).

I have "re-created" all of my primary stations from 1959 until present, having acquired the final 2 items (a Heath SB-200 and Collins 75A-1) in mid 2010. This equipment includes Heathkit SB-301/SB-401, Globe Chief 90A / Hallicrafters S-107, and a DX-100 with a Hallicrafters S-85. Also have re-created virtually all of my secondary stations. So far have obtained 75A-1, 75A-2, 75A-3, 75A-4, 51J-2, R-388, HQ-140X, SX-100, Mohawk, RME-6900 and several other receivers. Globe Champion 350A, Apache, DX-20, DX-35, Adventurer, and several other "boat anchor" transmitters as well. This includes the complete Eldico S-Line "clone" which was the "2nd source" required by the United States military for the Collins 32S-2 transmitter and 75S-2 receiver. The system consists of the T-102 transmitter, R-104 receiver, the station control (has wattmeter, SWR bridge, and phone patch), and the external power supply for the transmitter.

Have collected antique and vintage radios (from 1920s to 1950s) for over 40 years. This collection has been recognized by the Smithsonian Institution. Presently have about 100 units. Photos of some of these, my shack, and other items can be seen on my website http://k9sth.com as well as several articles on subjects of interest to many amateur radio operators.

Can be found on 160 meter SSB or CW, 75 meter AM, 40 meter CW, 6 and 2 meter SSB, and other bands from time to time. In addition, operate 2 meter FM, 70 cm FM, and 10 meter SSB mobile (especially when my wife and I are travelling to see our daughters who live outside of the Dallas/Fort Worth Metroplex (one in Scottsdale, Arizona, and one in Powder Springs (Atlanta area), Georgia, other one is still in this area). Have over 300 countries worked for DXCC, have been in many contests over the years, etc.

Joined AMSAT (AMSAT 239 / LM 463) the first couple of months of AMSAT's existence. Have operated on most satellites since OSCAR VI. Also am a member of the Society of Amateur Radio Astronomers.

"Acquired" rheumatoid arthritis in 2002 and have now become "officially retired" after being classified as "disabled" until February of 2010. Have been doing "boat anchor" repairs, manufacturing "specialty" parts for "boat anchors", chemical ground rods, writing magazine articles, and some telecommunications consulting. Also, was the head moderator for this site (QRZ.com) for over 10-years but retired about a year ago.

"Completed" my original Heath "twins" + VHF station a while back. This consists of an Apache, Mohawk, Warrior, SB-10, and AK-5 for 80 - 10 meters, and the Mohawk, AK-5, XC-6, XC-2, and Seneca transmitter for 6 and 2 meters. Also obtained an AM-2 SWR bridge that was sold along with the Apache and the B-1 balun kit. A while back I obtained the fairly rare Heathkit CA-1 Conelrad monitor that was sold to "kill" your transmissions if there was a Conelrad alert. This was a requirement for amateur radio operators into the 1960s.  In mid 2015, acquired a couple of more "modern", but still fairly old, transceivers, a Kenwood TS-440SAT and a Kenwood TS-830S.  Also have a Heath HX-10 Maurader SSB / AM / CW transmitter that needs to be restored.  Will probably replace the Apache transmitter, with the HX-10, in my Heath original twins station.

I you vist my webpage, http://k9sth.net , you will find quite a number of articles on all sorts of subjects of interest to amateur radio operators. There are also photos of my equipment, my antennas, examples of my QSL cards from 1959 until the present, older "shacks", a complete biography, and so on.
