Today’s amateur radio community networks began with just a few people linking sites to see what was possible. A microwave link between hilltops, an AllStar node, a tunnel routing traffic between friends…it all starts with someone trying an idea. What could you try with 44Net? #44net #44yearsof44net

Early 44Net traffic often moved at 1200 bits per second over packet radio. Today, many links run at millions of bits per second using modern equipment, often built by the same volunteer community. #44net #44yearsof44net #packetradio #amateurradio

44Net isn’t a “walled garden”. It's a shared address space that hams can build on, ranging from small local networks to international backbones. No top-down governance, just a common foundation. #44net #44yearsof44net #amateurradio
Today, the ‘AMPRNet’ project continues to carry a community-driven spirit through self-organized, community-run networks built on modern wireless links. #44net #44yearsof44net
ARDC's 2026 Community Meeting will be on Saturday, March 7, 2026 at 10a PST / 6p UTC. Looking forward to seeing you there! #ardc #amateurradio #digitalcommunications #hamradio #44net #ardcgrantees #science #technology
Volunteers have helped manage 44Net since its earliest days, when packet radio linked local networks. The ‘Regional Coordinator’ emerged to help support new operators and manage infrastructure. #44net #amateurradio #packetradio #amprnet #44yearsof44net
Snowed in during a Harrisburg, PA winter in Jan. 1986, Phil Karn KA9Q sketched what became CIDR notation for IPv4 addresses…on a napkin! #digitalcommunications #44yearsof44net #digitalinnovation #44net #technology
Registered on April 27, 1988, ampr.org is the 13th-oldest .org Internet domain name that is still registered today: https://en.wikipedia.org/wiki/List_of_the_oldest_currently_registered_Internet_domain_names#.org #ardc #44net #44yearsof44net
On January 25, 1986, a winter storm kept Phil Karn KA9Q, Bdale Garbee KB0G, Mike Cheponis K6THZ, and Bob Hoffman N3CVL overnight in Harrisburg, PA after a Mid-Atlantic Packet Radio Council meeting. This sparked the ‘Snowstorm Brainstorm’ that led to the formation of the TCP Group and today’s 44Net Community. #44net #44yearsof44net #amateurradiohistory #networkinghistory
