Does anyone know which mode is going on near #network105 on 14.105 ? I can hear #ax25 packets along with another mode, but I am not sure what that mode is.
@sergio_101 there's several modes there such as Robust Packet, IL2P 300 (perhaps 600 too) and ARDOP / VARA 500. Most of these have a center frequency +500 Hz or +1000 Hz higher than Network 105.
Fixed my #adsb receiver, hopefully- switched to a beefy AudioWind DC to DC regulator to go from 12V to 5V supply for the #raspberrypi - prior converter seemed unreliable. #electronics
@ai6yr@raymccarthy You screw it to the breadboard then press down on the end and slide a wire or component lead through it and let go where it will hold it by friction.
this past year alone, my family has faced evacuation twice in the #canadian north due to #wildfire. during the current evac, thousands of northerners have zero communication with their families, emergency personnel or access to wildfire data.
this is entirely due to the collapse of NorthwesTel's fibre network infrastructure and zero secondary systems for comms. the sub/arctic is infamous for its fragile, ancient comms architecture.
i want to change that, and i'd like help thinking out loud about potential citizen-owned/operated technologies for long-distance emergency comms.
#hamradio and #packetradio enthusiasts - could you please recommend some research resources on the following:
legal/frequency considerations for non-voice/packet transmission specific to #Canada
recommended hardware & software for 1000km+ transmission, tcp/ip
examples of amateur radio clubs that have undertaken this kind of role before
if possible, please respond with links to documentation, research and/or policy papers.
my entire family has worked wildfire management since the teletype days, and i hopefully can effect some actual useful change for northerners here.
@vga256 you could take a look at the P4 Dragon modems. Not cheap but very fast (for HF) & reliable and easily integrated into email systems https://www.p4dragon.com/
