Another example maybe we should try this again? is the PACSAT system, a data-communications protocol and hardware specification for Ham Radio satellites that combined multiple receivers with a of data. In the 1990s, PACSAT was proposed and several satellites were actually built and put into orbit. But then, PACSAT required dedicated, expensive, specialized hardware suitable only for a satellite. In the 2020s, a PACSAT system could replace a Ham Radio repeater with a software defined receiver (can now listen to multiple frequencies) and a few other off-the-shelf parts. The difference that DLARC makes is that all the original reference material for PACSAT can easily be found in DLARC. If some graduate student were to email me looking for a project, I can suggest that they create a “PACSAT 2025” – and point them to all of the PACSAT material in DLARC.
Many new Ham Radio Operators live in “restricted” living arrangements color correction as apartments, condominiums, or communities that don’t allow external antennas. Thus, to operate on the Ham Radio “High Frequency – HF” bands (shortwave) bands, some “creativity” is required – a stealthy antenna. One of my favorite collections within DLARC is 73 Magazine which was published monthly for 43 years, with many, many antenna construction articles such as the “compressed W3EDP” HF antenna that would fit into an attic. Unlike current Ham Radio magazines, all 516 issues of 73 Magazine can be browsed, and downloaded, and because Internet Archive does optical character recognition (OCR), every word of every issue is keyword searchable.That, is powerful and ample “food for the imagination” of Ham Radio Operators looking to the past for some interesting projects to tackle.
Those are just a few examples of the utility of DLARC from my perspective. Ham Radio has existed for more than a century, but prior to DLARC, there was no comprehensive online archive of Ham Radio material. There were some personal archives, some Ham Radio clubs and organizations had their newsletters online, but there was no comprehensive online archive of Ham Radio material. DLARC is now the archive that Ham Radio has been missing. Most significantly, unlike some Ham Radio organizations, material in DLARC is free for public access (though some material is subject to Controlled Digital Lending). DLARC includes club newsletters (from all over the world), Ham Radio books and magazines (some from very early in the 20th century), audio recordings, video recordings, conference proceedings… literally a treasure trove of knowledge and ideas and inspiration.
