I was first licensed in 1970 and earned a BSEE degree in 1975 from the Rochester Institute of Technology. (Loved operating the club station K2GXT with college buddy Fred W2UB back then!) I've been in high technology assignments all along, specializing in hardware and embedded software development ... Eastman Kodak, Edsun Labs, Dialogic Corp, SafeNet (CTO) and McAfee (Chief Scientist), Vir2us (CEO), and BlueFin Security (founder). I'm currently at LifeJourney where we've created a career exploration and mentorship platform that inspires high school students across the nation to pursue STEM education and career paths.
Here's the main station, used primarily for CW and digital mode operation ...
And here is the beloved boatanchor station, used primarily for AM. Components include: an National NC-183D (an original find, first out-of-the-box in 2009!), a Viking Invader 2000 (currently being re-vamped for better audio), a great-performing Collins R-390. and the Heathkit station (HR-10B, DX-60B, HG-10B, HO-10 and HM-11), which re-creates my first staion back when I started out. An "HBR-16" receiver is being homebrewed into the Collins case, and an another exciting project in progress is a Class E AM Transmitter ... a digital-drive (PWM) modulator with a 24-MOSFET final stage providing a cool and efficient 1KW RF output on 80m/160m.
Along with Joe N2CX, my decades-long elmer, design partner, collaborator, humorist and overall best friend, I've played a lead role in the New Jersey QRP and American QRP clubs, and have been active in the QRP scene since 1996. Along the way we've organized the annual Atlanticon QRP Forums, edited/published the quarterly "QHB" and "Homebrewer" magazines, and I'm a member of the ARCI "QRP Hall of Fame". Together Joe and I host a bi-weekly Internet radio program called Chat With The Designers (www.cwtd.org) where we have over 70 episodes chalked up with great technical material and audio podcasts available for every episode.
An inveterate homebrewer with strengths in software and digital design, I have co-designed the Micro908 Antenna Analyzer, the DDS-60 card and numerous other kits for NJQRP and AmQRP. Among my latest projects, co-created with Milt W8NUE, is a single board controller for portable PSK31, called the NUE-PSK Digital Modem, for which articles were published in QST (Mar 2008), QEX (Mar-Apr 2008), and Circuit Cellar (Design Contest 2007).
Another co-design project, with Juha OH2NLT, is the SDR Cube Transceiver, which is an embedded SDR transceiver for CW, SSB, AM and Digital modes using a Softrock for the RF front end and an embedded software HF modem. A great friend of mine down in the Florida panhandle, Barry WB6LDL, just loves using his SDR Cube Transceiver barefoot for CW QSOs, and then with along with a pre-production RF PowerCube for his AM contacts - he loves it and claims the audio purity on receive is unbelievable good! The Cube product line is expanding this year (2016) with a 5W driver amp, the "RF PowerCube" 20W PEP amplifer, amplified speakers, and a Signal Quality Meter with color graphic display of SWR, power, IMD, 2-tone modulation, RF envelope, optimal digital modulation shapes, and CW weighting, rise/fall times, and over/undershoot ... and maybe even an option to package all this in a new, slightly larger enclosure ... Super Cube? ;) Having some real fun with the SDR Cube development!
The most recent project, along with co-designer Dave AD7JT this time, is an exciting handheld Scalar Network Analyzer with a color graphic display and touch screen, which proves to be an inexpensive kit for measuring performance of LPFs, crystals, antennas and other devices. Dave and I are talking about the SNA this year at the Trenton Computer Festival, Ozarkcon, Dayton, TAPR DCC (hopefully) and the VHF Conference.
I can't seem to get enough RF test equipment. It's not the newest, not the neatest, but it sure is the handiest for actually *seeing* performance of the projects. It's easy to say "Works great 'cuz I QSO'd with Japan" ... but it ain't real for me unless I can measure it! Good friend and co-designer Juha OH2NLT, and best bud N2CX have helped me build up my RF measurement skills and techniques over the years - thanks guys! (The photo is a makeshift panaoramic view) ...
73, and hope to catch you sometime on the bands or on the CWTD radio program!
Theodore, Guardian of the Shack ... at my feet most evenings while working down here.
