More Exciting than War and simultaneously More Regenerative than Peace

2024-10-31 Meshtastic and Portland Neighborhood Emergency Teams City Wide Deployment exercise [my old days]

_ Portland had Neighborhood Emergency Teams City Wide Deployment exercise as a part of IronOR 24 statewide exercise last night.

_ I joined Irvington neighborhood team as known as 🦺　meshtastic nodes.

_ I was a bit surprised because the private channels were more useful than I was imagining.

_ We also used FRS radio and GMRS radio.

_ seeing history of communications visually is very complimentary to real time radio audio communication.

_ My learning was:

_ putting message numbers like #1 #2 #3 manually.

_ ask receivers if they get message #1 to #3.

_ the sender get some level of idea if receivers got the messages.

2024-10-18 Meshtastic BBS practicality [my old days]

_ I have compared Meshtastic BBS (TC²-BBS) practicality using LongFast, MediumSlow and MediumFast at SE Portland residential area.

_ I thought LongFast had advantages because of reach and other nodes hop.

_ Actually LS was about 0.5 miles practical distance and MS was about 0.9 -1.0 miles practical distance.

_ Antenna was original and hight was first floor.

_ That means typical one neighborhood in SE can be covered by one or two BBS nodes.

_ I also noticed when I used my BBS, the channel utilization went to 30-32% using LF. 15-17% using MS.

_ MF was about 0.8-0.9 miles practical distance. I also noticed when I used my BBS, the channel utilization went to 3.3% using MF.

_ LF 0.5-0.8 miles-30-32% util

MS 0.9-1.0 miles -15-17% util

MF 0.8-0.9 miles - 3.3-3.4 % util

_ LF is about 55 active nodes in two hours means about 15-20 % ch util usually. MS and MF both are pretty empty here.

_ All testing points are very few. So this results are just rough impressions base.

_ I noticed LF sometimes need long waiting time to see responses from BBS.
