BEHEMOTH Visits Radio Fun/73

During my 1992 Mothership jaunt around the US, one of my fondest memories is an extended visit to Peterborough, New Hampshire… home of the the late Wayne Green (W2NSD) and his publishing empire, along with all sorts of interesting people. My old editor and friend from 73 Magazine, Bill Brown (WB8ELK), was running the spin-off…

The Icom IC-725 – 73 Review

The ICOM IC-725 An experiential viewpoint. by Steven K. Roberts N4RVE 73 Magazine — February, 1990 This is not a normal equipment review. There are no lab test results and no objective comparisons between this unit and anything else on the market. My new ICOM 725 did not arrive with a 73 product-review assignment attached, nor…

The Spectrum Probe

by Steven K. Roberts N4RVE 73 Magazine — January, 1990 The Spectrum Probe Inexpensive and portable spectrum analyzer. There’s nothing quite like the frequency domain for revealing what’s going on in a system. Down in the slow-moving mechanical world, Fast Fourier Transform (FFT) analyzers are used to determine the resonance characteristics of structures and to help…

The Portal System – 73

Back in the late 1980s, the amateur radio packet community was well established, though the tools were “thin” in the sense of being slow, difficult for newbies, and not exactly useful as a deep archive. This was an era when competing online services were flourishing (like CompuServe and GEnie), and each had forums or roundtables…

Instant Track – 73 Review

In 1989, I was passionately in love with the OSCAR 13 satellite, as well as laying the groundwork  for use of the Microsats from the new version of the bicycle. My KLM crossed-yagi antenna array had to be aimed at the right spot in the sky to work the birds, and I used what was…

Jatich KA9KAG 73 Magazine — November, 1989 “Suburbia is not a place; it’s a state of mind… You live in suburbia when the cycle of work and play becomes dangerously unbalanced in favor of work.” (Computing Across America, page 3.)

Packet Radio and High-Tech Nomadics

These magazine articles from the early phase of BEHEMOTH development are kind of a treasure… I had not yet started posting the details to a mailing list, and there aren’t many documents that go into detail about the system design. My series in 73 Magazine was very liberal, editorially… so I was free to ramble…

The Hacker’s Shack

Transceiver from a spectrum analyzer and tracking generator? Before SDR, we had… The Hacker’s Shack by Steven K. Roberts N4RVE 73 Magazine — January, 1989 This is an interim of sorts — a time of misleading stability between bouts of nomadness. It’s a respite from tire itch, a chance to develop a pot belly with…

Life on a Megacycle

This article is about HF amateur radio on the Winnebiko II back in 1988, and is one of my favorites from the 73 Magazine series. It discusses the rig and antennas on the bike, of course, but also rhapsodizes about being a roving guest-op, cultural issues, expressiveness in CW, learning, techno-passions, and so on. This…

The Quest for Ultra Portability

Part 7 in the High-Tech Nomad series by Steven K. Roberts N4RVE 73 Magazine — August, 1988 When I first set out on my strange 8-foot-long, 140-pound bicycle back in 1983, I received a lot of serious advice from my Ohio neighbors. “Never turn onto a road with ‘mount’ or ‘hill’ in its name,” said one…
