Here is a puzzle I am trying to solve
Does any one know that any of the following would have been used for
or were part of.
1/4 WAVE GP ANTENNA 433.0
G-E UHF TRX 433.01 MH
TNC SPIRIT 3 ( 145.01, 145.15, 433.01.)
HB9CV UHF ANTENNA 433.01
One may have think back to what was going on in 1993 or 1994
This was all part of the packet radio network that was in operation (starting in the 1990s) until it was decommissioned in the late 90s/early 2000s.
The users would access the system using TNC (radio modem) 1200baud nodes operating on 2m frequencies; 145.01Mhz via simplex, and 145.15Mhz via a repeater that had been built by VE6KQ. The nodes themselves were connected via higher speed 9600 baud links on the UHF frequency 433.01Mhz.
The following quote which is still listed on the current CARA webpage partially describes this system: " CARA currently operates a terrestrial LAN through southern Alberta, a satellite gateway from Calgary to Allen Park, Ontario and Ottawa , Ontario and a full-time connection to the Internet through SHAW."
