Using Autopatch on DFMA Repeaters
Autopatch allows access to the phone network through repeaters that
include the necessary hardware. It allows for emergency or short personal
conversations. (Non-personal use is not allowed by your amateur license.)
This service may be useful if cell phone access is not possible. (Forgotten
cell phone, dead battery, no service, etc.)
Use of autopatch requires the use of a numeric pad on your radio including
the "*" and the "#" keys. DFMA policy requires you to ID with your
callsign before use. Lack of ID subjects you to summary disconnection by
a control operator. ID after completing your use is the standard FCC
To connect: ID, then
Press PTT and dial * + 919 + 7 digits
or * + 984 + 7 digits.
Do not release your PTT in the middle of this sequence;
this will cause it to fail.
Interruptions in fringe areas due to
dropouts or interference can also cause failure.
When the connection is made, inform your party that whatever they say
is public. This is half duplex. You cannot both talk at once. Your
signal has precedence. You are limited to 3 minutes!
To disconnect: press "#" then ID.
Use 911 for Durham County emergencies or 910 for Orange County
emergencies. (Consult your DFMA Repeater Guide for other options.)
To connect: ID, then
Press PTT and dial * + 911
or * + 910

a ham radio relay and the dispatcher's location

not the location of the emergency.

signal has precedence,
To disconnect: press "#", then ID.
