The card for the worst day.

One page: the repeaters, nets, weather radio channels and mesh nodes around you, with frequencies and tones. Print it and it keeps working when the phone is dead, the tower is down and this website is unreachable.

Fold it into the go-bag. It works with a dead phone.

Emergency contacts

  • Life-safety emergency 911Radio is never a substitute for 911 when someone is in danger.
  • mPING app · mping.nssl.noaa.govAnyone can report precipitation type, hail, wind damage or flooding straight to NOAA - no training needed, anonymous.
  • Wireless Emergency Alerts your phone · Settings → NotificationsKeep Tornado and Flash Flood WEA alerts on. ChatterBack emails are a supplement, not a replacement.
Distances are straight-line from the centre point, not coverage. A repeater 30 miles away over a ridge may be unusable; one 40 miles away on a tower may be fine. Listen before you transmit. Tones shown are the encode (transmit) tone.An offset of “?” means our source didn’t supply one - find it before you key up, and don’t assume simplex. Some coordinates are town-level rather than the actual site, so a very short distance may just mean “in this town”.
