Store and Forward episode 6 — The Problem Box

The video version of this episode is at: https://archive.org/details/store-and-forward-6

Kay discusses a subset of the ongoing DLARC project of Bob Cooper archive – https://archive.org/details/bob-cooper, discussing an obscure newsletter of Cooper’s called “Coops Technology Digest”. Despite the donation of a container full of Cooper’s personal archives to DLARC, there were missing issues of this interesting newsletter. Steve joked that the missing issues might be “forbidden knowledge”. Kay managed to track down some of those missing issues to two libraries in New Zealand (where this newsletter was published) in hopes that they’ll help DLARC and digitize the missing issues in their collections. 

Kay discusses an obscure Amateur Radio publication called The Low Band Monitor that was donated by the California Historical Radio Society – https://californiahistoricalradio.com and the DX-Peditions Collection – http://archive.org/details/dx-peditions.

Kay discusses the issue of “The Problem Box”, where well-meaning folks “throw stuff into a box” for donation to DLARC. Unfortunately, random, uncategorized, unsorted material like this are problematic for the Internet Archive scanning folks who want to “just get the scanning done” as efficiently as possible. Thus Kay needs to step in to figure out what the material is, organize it, assign metadata, and assess its priority for scanning. All Amateur Radio material is welcome for DLARC, but sometimes the human touch of an archivist like Kay needs to get involved (and that’s one of Kay’s many roles in managing DLARC).

Finally Kay does another quick on-screen tour through the DLARC Wantlist of items that are known to exist, but have not yet been found or donated to DLARC such as missing issues of a magazine or newsletter.

Steve discusses his enthusiasm for the M17 Project, which he has been covering extensively in recent issues of Zero Retries. M17 began as a well-developed open source specification for Amateur Radio digital voice and data in VHF / UHF bands. M17 has now been developed into a number of different hardware and software projects. In the past few months, a new M17 radio was developed – the Connect Systems CS7000 M17 – the first radio that does M17 “out of the box”. M17 is now at the point where “all the pieces are available” for M17 to be used as a Digital Voice repeater system on VHF / UHF, equivalent to semi-proprietary digital voice systems such as DMR, D-Star, and System Fusion.

That M17 is an entirely open source system is causing a lot of excitement and interest in newer, younger, techie Amateur Radio Operators with a strong preference for using only open source systems in Amateur Radio. Amateur Radio “powers that be” don’t get why M17 being open source is different enough to justify changing their repeaters to allow M17, but some progressive Amateur Radio clubs do get it, such as Mount Diablo Amateur Radio Club sponsoring a dedicated digital voice repeater which includes M17 as “just another digital voice mode” – https://www.mdarc.org/repeater-systems/digital-voice.

As an example of why M17 being an open source project makes a difference, a recent project of M17 added public key / private key “signing” of M17 transmissions; if a public key signature is known (and trusted), a transmission that is “signed” with a person’s unique public key can be reasonably trusted to be from that person (who is the only person who can create a public key with the use of their unique private key).

Steve is also enthusiastic about M17 because it is unique among the digital voice systems that was developed from the beginning to accommodate data transfers on an equal priority basis with digital voice transfers. A recent development by M17’s primary developer created a prototype dedicated messaging app for M17.

Steve does yet another passionate plug for the entire run of 73 Magazine – https://archive.org/details/73-magazine being publicly available on DLARC with no restrictions, to anyone in the world… in marked contrast to other publications from the “Amateur Radio Publishing Industrial Complex” (Amateur Radio publications hidden behind a paywall). Kay put in a plug for another great magazine – Monitoring Times – https://archive.org/details/monitoringtimes that gave permission to be publicly available on DLARC.

Store and Forward episode 5 — Admiral Hopper

Video version of this episode: https://archive.org/details/store-and-forward-5

Kay and Steve were prepared to tell each other about a great, newly released video of US Navy Rear Admiral Grace Hopper’s 1982 talk to the US “No Such Agency”. In these videos, the late Admiral Hopper was in great form, with lots of humor and history about her career in the US Navy. She begins the talk reminding everyone that the first electronic computer was built by the US Navy. Title of the talk was “Future Possibilities: Data, Hardware, Software, and People”. Both Kay and Steve highly recommend these two videos.

Kay discusses another portion of the ongoing DLARC project, the Bob Cooper Archive https://archive.org/details/bob-cooper

Steve discusses the main story in Zero Retries 0166 (published 2024-08-23), the new Masters Communications DRA-Pi-Zero, a new Amateur Radio data communications interface (essentially, a modem for radios) – https://www.zeroretries.org/i/147797445/the-new-dra-pi-zero. This unit is just another option for using the very cool software called DigiPi created by Craig Lamparter KM6LYW – https://craiger.org/digipi/.

Steve discusses another trend he is tracking in Zero Retries – the messaging capabilities built into Automatic Packet Reporting System (APRS) – http://www.aprs.org/aprs-messaging.html. APRS Messaging has been available and usable for years, but generally poorly implemented being built into radios where you can only input text with the buttons on the radio’s microphone. The Meshtastic app (https://meshtastic.org/), used on unlicensed bands like 902-928 MHz in the US, is showing how “messaging” can be… and should be… much more usable. Example apps in Amateur Radio are RadioMail – https://radiomail.app/ and VarAC – https://www.varac-hamradio.com/. Steve will be “encouraging” the development of “Messaging First” apps for APRS messaging in future issues of Zero Retries.

Steve mentioned a cool new press release from the National Radio Astronomy Observatory (NRAO) and Amateur Radio Digital Communications (ARDC):

Unlock the Secrets of the Invisible Radio Universe with SuperKnova®
Funded by a grant from ARDC, the National Radio Astronomy Observatory (NRAO) has developed two no-cost, self-paced online courses on SuperKnova, an online educational platform accessible to learners of all ages: the Technician Amateur Radio License and EMS Course and the General Amateur Radio License and EMS Course. These courses introduce the fundamentals of the electromagnetic spectrum (EMS), which will not only help learners get their amateur radio license, but will also contribute to the longevity of the amateur radio community. In addition to applications in amateur radio, these concepts taught in the courses are also applicable in many career paths.

One of the NRAO facilities is the array of big dish antennas in New Mexico that was a primary location in the movie “Contact”.

Steve’s big task in the next few days is to assemble his thoughts and comments in preparation for filing comments by the deadline on the “Spectrum Grab” currently in progress for the US 902-928 MHz band. The deadline for those comments to be filed by the FCC is next Thursday 2024-09-05. He plans to do a special mid-week issue of Zero Retries just on this topic.

Store and Forward episode 4

Kay discusses their trip to Lima, Ohio to Fair Radio Sales – https://fairradio.com/, one of the last true military and government surplus stores (mostly electronic equipment). Fair Radio Sales is going out of business so the owner can retire. The business and its inventory is being auctioned and everything must go including a large amount of documentation. The owner of Fair Radio Sales agreed to allow Kay and DLARC to go through that documentation prior to Fair Radio Sales’ auction. Two vanloads of ~200 boxes were transported to the Internet Archive’s scanning facility in Fort Wayne, Indiana. The material will be scanned and added to the Digital Library of Amateur Radio & Communications.

In this week’s Zero Retries 0165, Steve discusses Zero Retries hitting 2,000 subscribers. Last week’s Zero Retries 0164 featured a story about his visit to the US Navy Arleigh Burke-class Destroyer USS Sampson (DDG 102) during Seattle, Washington’s Fleet Week 2024 – https://en.wikipedia.org/wiki/USS_Sampson_(DDG-102)

Steve discusses his ongoing education about the M17 digital voice / data system – https://m17project.org/ developed as an entirely open source project and why that really matters in Amateur Radio, especially new techie Amateur Radio Operators as those getting their Amateur Radio license at DEFCON 32 this past week – DEF CON 32: Another mind-blowing experience – https://www.kb6nu.com/def-con-32-another-mind-blowing-experience/.

Steve also discusses the newest threat to Amateur Radio operations in the 902-928 MHz band which is shared between licensed users including Amateur Radio and license-exempt uses such as Automatic Meter Reading (AMR) and most recently, Meshtastic – https://meshtastic.org
