73 Magazine Archives - Nomadic Research Labs

This article in 73 came long after my series of the late eighties, focused on the Winnebiko II and the technomadic tools of that era. Written more than a decade later, this is a rare overview of the Microship project… twin amphibian pedal/solar/sail micro-trimarans under intensive development in a remote northwest forest lab. by Steven…

I fell in love with the Ultratorch butane soldering irons from Master Appliance after visiting them in Racine during the BEHEMOTH adventure, then incorporating two of them into my mobile lab. This article describes these lovely little tools… written for 73 Amateur Radio Today magazine. The Ultratorch — a Tool for Liberation by Steven K.…

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…

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 have I really given the issue much…

by Steven K. Roberts N4RVE 73 Magazine January, 1990 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 predict failures. In RF…

Now you can easily explore ham radio’s most fascinating on-line forum! 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…

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…

A view of Steven K. Roberts N4RVE’s book. Review by Alida M. 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.) If you’re like me, there…

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…

Transceiver from a spectrum analyzer and tracking generator? Here’s a glimpse of a hacker’s shack before SDR. 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…
