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 requirement.

Personal Autopatch

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.

Emergency Autopatch

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

When the connection is made, you may need to explain that you are using a ham radio relay and the dispatcher's location indication will be that of the repeater site, not the location of the emergency. This is half duplex. You cannot both talk at once. Your signal has precedence,

To disconnect: press "#", then ID.
