About
How this site evolved from the Southern Ontario Packet Radio Association archive into a working resource on radio infrastructure, community broadcasting, and online radio.
PacketRadio.ca was, for nearly two decades, the official web site of the Southern Ontario Packet Radio Association — SOPRA — the volunteer body that coordinated AX.25 packet networks, BBS forwarding, APRS digipeaters, and 220 MHz backbone links across the Greater Toronto Area, the Niagara peninsula, and surrounding regions. If you reached this domain ten or fifteen years ago you would have read network news about VE3CON in Weston, VE3INF in Acton, VE3PRC in Brampton, the proposed VE3PRC–VE3TDS link, and a dozen other operational details that mattered enormously to the few hundred operators who ran the equipment.
Most of those nodes are off the air now. The 220 MHz backbone that linked them came down years ago. Some of the operators have become silent keys. The packet protocols themselves — AX.25, NET/ROM, AXIP — still work, but the network they once formed has largely faded into a few enthusiast pockets and the historical record. We have preserved the node archive for anyone researching that history.
Domains like this one rarely get a careful second life. The usual fate of a lapsed amateur radio site is either total abandonment or being repurposed into something completely unrelated — a forex blog, an SEO link farm, a generic technology page that has nothing to do with radio. Neither felt right. The original site was about radio communications and how a community of operators kept regional infrastructure running on volunteer time. That subject matter is not dead. It has just shifted form.
So PacketRadio.ca continues as a Canadian editorial archive about radio systems, distributed networks, and the practical infrastructure of independent broadcasting. Some of what we publish is straight historical preservation. Some is bridging material that explains how packet-era thinking maps onto modern digital radio, IP-delivered audio, and software-defined transmitters. A growing portion is forward-looking work on community radio, online stations, low-cost broadcast infrastructure, and how small communities reach an audience without a national broadcaster’s budget.
We are not a music blog. We do not curate playlists, profile artists, or run interviews with on-air talent. There is nothing wrong with sites that do those things, but mistaking PacketRadio.ca for one would lose what is actually interesting about the subject. Radio infrastructure is the part of broadcasting that nearly always goes uncovered, and the part that decides whether the music ever reaches anyone.
We do not sell anything. There is no membership, no paywall, no newsletter capture, no affiliate links pasted into articles. Where we link out, we link because the destination is genuinely useful — usually to Radio Amateurs of Canada, ISED’s Spectrum Management documents, the ARRL’s technical archives, or the Internet Archive’s preservation of older amateur publications.
Pieces are written long. We’d rather explain something properly than chop it into bite-sized SEO bait. Articles assume the reader is curious and willing to follow a paragraph through to the end, but they don’t assume prior radio expertise. Where a term first appears we try to explain it, even if that means saying out loud what experienced operators consider obvious.
We cite sources where it matters. We use our resources page to keep a running list of the documents, archives, and reference sites we draw from. If you’re researching anything in the legacy section and want primary sources, that’s the place to start. We also link freely between our own articles — this site is meant to be read laterally, not just landed on once.
Corrections are taken seriously. If you spot an error — a wrong frequency, a misremembered date, a misattributed call sign — send a note and we’ll fix it. The goal is to make this archive trustworthy enough that future researchers can rely on it.
This site is not the official voice of any current organisation. SOPRA as an active body has not held meetings or coordinated network operations for some years. We continue the domain in good faith, with respect for the operators and volunteers who built and maintained the network in its working years. Where we publish historical material, we’ve tried to capture it accurately. Where we publish modern material, we make clear that it represents the editorial position of the site, not a successor organisation.
If you operated a SOPRA node, contributed to one of the BBS systems, or have documents and photographs from the active years that you would be willing to share for archival purposes, please get in touch. We are slowly assembling a more complete record and any first-hand material is genuinely valuable.
