All previous issues of Zero Retries are available without restriction (no paywalls). For some background, Zero Retries 0000 was the Introduction Issue. Zero Retries 0026 and Zero Retries 0027 were a 2021 Year End Review of Zero Retries. Every “decade” issue of Zero Retries is an overview of “Zero Retries Interesting” projects, etc.

Zero Retries is a unique, quirky little highly independent, opinionated, self-published newsletter about technological innovation in Amateur Radio, for a self-selecting niche audience, that’s free (as in beer) to subscribe.

Zero Retries began publishing in July, 2021 and is published every Friday at 15:30 Pacific. For an overview of the genesis and goals of Zero Retries, see Zero Retries 0000 - The Introduction Issue.

Zero Retries tries to highlight some of the incredible technological innovation that is occurring in Amateur Radio in the 2020s. It was created to try to offset the “same old, same old” perspective of “the Amateur Radio Publishing Industrial Complex” that hides most of its content behind paywalls, and on the rare occasion it features an innovation in Amateur Radio, portrays it as a one-off innovation instead of explaining that it’s just one innovation of many in this era.

The name Zero Retries is derived from Amateur Packet Radio where (like the Internet) a data transmission is divided into “packets” and each packet is tagged with a “checksum” that is unique to that packet. When the packet is received, the receiving station compares the checksum to the data received. If the checksum is correct (for the data received) the packet is assumed to be good. If the checksum is not correct, the receiving station sends a request to the transmitting station to re-transmit the packet (a Retry). The most ideal state of packet radio communications is that “Zero Retries” are required.

In Zero Retries, some “buzzwords” from Amateur Packet Radio are playfully used.

  • Request to Send is the Editorial section of Zero Retries, and is derived from the RS-232 data communications standard where one of the signals in RS-232 is “Request to Send” so that the Data Transmission Equipment (DTE) (modems) and Data Communication Equipment (DCE) (terminals) stay in synch because DTE’s typically had small buffers. So, Request to Send is a playful way of saying “May I please have your attention?”). Prior to Universal Serial Bus (USB), RS-232 was the primary serial communications standard, including on Packet Radio Terminal Node Controllers (TNCs).

  • ZR > BEACON is Zero Retries’ “short news blurbs” section of news items I judge to be “Zero Retries Interesting” but not long enough (or not enough space for) a full article. In Packet Radio, a beacon is a brief “announcement” transmission, not directed to any station in particular.

  • Feedback Loop is a term from electronics, where a portion of the output signal is fed back into a circuit regulating the input. That seemed an appropriate and techie label rather than a mundane functional title such as “Comments to the Editor”.

There are four significant limitations of Zero Retries:

  • Trying to keep up with technological advancements in Amateur Radio is a “drinking from a firehose” exercise; there is so much going on that inevitably, some significant developments don’t get mentioned in Zero Retries because new developments keep occurring.

  • Zero Retries is primarily an email newsletter. The (current) publishing system for Zero Retries is Substack (see below) and Substack, mindful of the restrictions of large email service providers such as Gmail, limits the size of email newsletters to what those email service providers consider acceptable. There’s only so much room in each edition of Zero Retries.

  • Zero Retries content is generated by one person, though on occasion, content originally published elsewhere is republished in Zero Retries with permission.

  • Zero Retries is written by an Amateur Radio Operator who has lived his entire life in the United States, with little real world exposure to Amateur Radio in other parts of the world. That’s not from lack of desire or interest to cover technological advancement in Amateur Radio in other parts of the world - I’d love to. Want to help with that? Please contact me.

The Zero Retries Unabashed Merchandizing Division was started in March 2022 will start “Summer 2022”. It was going to be named something else that was popularized by a certain radio show about “cars”, but turns out they were smart enough to copyright that phrase. 🙁 Think of ZRUMD as a friendly garage sale, slowly liquidating Amateur Radio (mostly) ephemera to a friendly crowd.

Inspirations for Zero Retries:

Inspirations for Zero Retries are almost too many to count, but it’s only fair that I try to cite them given the inspiration they have provided to me. There are many other influences I will (eventually) cite, such as magazines, but these are the newsletters:

  • The name Zero Retries as a name for a newsletter was created by Budd Churchward WB7FHC for the newsletter of the now-defunct newsletter of the Northwest Amateur Packet Radio Association (NAPRA) based in Western Washington, USA. I have many, hopefully most, of those print newsletters. I owe it to the memory of NAPRA and the original Zero Retries to scan them and put them online. More than three decades after my participation in NAPRA, both WB7FHC and I found ourselves in Northwest Washington (near Bellingham, Washington) where we are now collaborators in various projects involving Amateur Radio data communications.

  • ARRL’s Gateway Newsletter - you’d never know that this newsletter ever existed (1984 - 1990) by browsing the ARRL website. It’s inexplicable to me that there’s no mention of Gateway there because Gateway was the newsletter that knitted the disparate groups, developers, and networks together and progressing more or less in unison during the early to middle years of the birth and growth of Amateur Packet Radio. Each biweekly issue brought interesting, useful, and often actionable news about Amateur Packet Radio.

  • It’s not quite the same publication as it was in the glory days of Packet Radio, but the TAPR Packet Status Register newsletter (1982 - present) was a profound influence on me. I wrote several articles for PSR, and was very briefly an editor. I used one article I wrote for PSR as a writing sample in my application for a columnist position, and that position changed my life.

  • It’s almost two decades since the last issue, but David Isenberg’s The SMART Letter was another profound influence to me on what, and how good, a newsletter with a solo, profoundly competent voice could be. Isenberg was famously the author of a profound essay called The Rise of the Stupid Network which foretold the rise of the Internet and the inevitable decline of the Public Switched Telephone Network - PSTN (as the be-all-and-end-all of telecommunications). The SMART Letter illustrated to me just how much influence one voice can have. After more than a decade of being out of touch, I’m now in regular communication with Isenberg.

About the Editor:

My passion in Amateur Radio has always been data modes and other technology oriented activities in Amateur Radio. In the 2020s, I’m semi-retired and working on passion projects like Zero Retries and dabbling on projects in N8GNJ Labs. Although I’m not yet active in Amateur Radio satellites, to do so is in my plans. Ditto microwave (mostly networking).

I also participate as a volunteer (2021, 2022) at Amateur Radio Digital Communications (ARDC), Mount Baker Amateur Radio Club Digital Group (DG), and Whatcom Emergency Communications Group (WECG). I live (very close) to beautiful Bellingham, Washington, USA.

My other writing outlets include my personal Amateur Radio Blog N8GNJ.org and Superpacket, a blog about the big picture of Amateur Radio (something of a precursor to Zero Retries).

About the Assistant Late Night Editor:

Jack Stroh, Zero Retries Assistant Late Night Editor (Emeritus), was profiled in Zero Retries 0031. Jack is now a Silent Keyboard (Zero Retries 0042) and prior to his death had retired from his role as Late Night Assistant Editor due to illness (Zero Retries 0038).

About the Zero Retries Pseudostaffer(s):

When Zero Retries began, the following were unfailingly encouraging about Zero Retries. I paid close attention to their respective blogs that occasionally featured “Zero Retries Interesting” subjects. Thus they were, for a time, named as a (entirely imaginary title) Zero Retries Pseudostaffer:

I’m grateful to these now retired pseudostaffers:

All of them remain trusted advisers, and I’ll always accept their call, email, and input.

About Substack:

Substack is an excellent platform for authors to create and publish email newsletters, including a well-developed subscription fee mechanism. I recommend Substack as it has proven to be reliable and consistent, and constantly evolving and improving.
