USA Emergency SHTF Frequencies: From ARRL Net Directory

HERE is the original document from which they mangled theirs:

USA-PREPCOM: A suggested radio coms standard for USA preppers

From Original Concept By R-UK, as Adapted for US Band Plans by KE4SKY

The objective of the USA-PREPCOM is to coordinate between licensed amateur and unlicensed citizens band, Family Radio Service, Multi-Use Radio Service and other USA based survivor radio stations following a major disaster in which conventional telecommunications have ceased.

For easy mnemonics the standard is the RULE OF 3S
3 is the important number. Remember it!
The 3 parts to the Standard are:

• 1/3:WHEN (Time coordination so we all know WHEN to call and listen)
• 2/3:WHERE (Frequency coordination so we all know WHERE to call and Listen)
• 3/3:HOW (Radio set-up so that everyone’s transmissions are compatible)

What’s this document for?

It is intended that this document be printed and stored in a water and light-proof pouch which is to be kept with stored radio equipment intended for disaster communications.

PART 1/3 =WHEN
Everybody looking to communicate needs to coordinate the time at which to do so.
By coordinating times and limiting operational time window precious electrical power will be conserved

Rule of 3s again:
Start communication sessions On the hour
Every 3 hours (starting 00.00h)
For 3 minutes calling and listening, if nothing heard, close the station and try again at next scheduled time.


Note, if a contact is made it is good practice to move communications to another channel / frequency so that the emergency calling channel is freed for other users
There is no requirement to end it after the magic 3 minutes, it can continue as long as required, but bear in mind power consumption.

PART 2 =WHERE
Where relates to Frequency coordination so that everyone is also communicating on compatible frequencies, failure to coordinate frequency is like not knowing the direction in which to flash a torch to signal to someone at night. We need to know exactly where to send and where to look.

Rule 2 is broken into two parts 2a for simple License-free transceivers (CB, FRS and MURS walkie-talkies), whereas 2b Ham is a full version incorporating both license-free and USA Ham frequencies.

PART 2a =WHERE License free
So for license free, the RULE of 3 continues. Set your radio to one of the following:

• AM only US CBs = Channel 03 26.985 Mhz AM US band
• SSB capable CBs = Channel 33 27.335 MHz USB
• FRS and GMRS = Channel 03 462.6125 MHz FM- NB (CTCSS/ DCS code turned OFF)

• FM-NB only MURS = Channel 03 151.92 MHz FM-NB MHz (US band)

PART 2b/3=WHERE Full version
