  • How about doing the same thing for some additional communication modes, too?

    • Put a list of critical phone numbers (including fax numbers, pager numbers, cellular numbers) in your kit.
    • Make sure your local packet digipeater has battery backup.
    • If you are likely to be assigned to a school, church, or office building, see if you can get a copy of the instructions for using the fax machine to keep in your kit.
    • If the phones are out, know how to interface the fax machine to your radio.


    Advance scouting

    • Advance scouting

      • It is a good idea to see if fax machines are in place and whether they will be accessible in an emergency.
        • Is there a supply of paper available?
      • Are the packet digipeaters within range of every likely communication post?
      • Can computers be made available or will hams have to provide their own?
      • How will backup power be provided to the computers?
      • Can a frequency list be developed, along with guidelines of when and how to use each frequency?


    Contingency planning = critical importance

    • Contingency planning = critical importance

      • How many times has a repeater gone down, and only then did the communicators wish they had agreed in advance on an alternate simplex frequency?
      • What will you do if you need to send a map and the fax machine power fails?
      • Suppose you are relying on cellular phones and the cellular network fails?


    Training

    • Training

      • Manning roster, assignment lists, and contingency plans
      • Questions you might want to ask are:
        • Who knows how to use a cellular phone?
        • Who knows how to use fax software?
        • Who knows how to upload or download a file from a packet BBS?
        • Who knows how to touch-type?






    Make a list of the kinds of messages that might need to be handled during a communication emergency likely in your area. Match the kind of message (tactical messages, served agency manpower requests, welfare inquiries, medical information, casualty lists, requests for supplies, shelter resident lists, etc) with the appropriate communication mode(s) (packet or other digital modes, FM phone, CW, HF SSB, etc.)
