YAESU FT3DR C4FM-FM 144-430MHz Dual Band Digital Transceiver Instruction Manual

**YAESU FT3DR C4FM-FM 144-430MHz Dual Band Digital Transceiver What is

the GM Function?**

The GM (Group Monitor) function automatically monitors on the same frequency for any other stations with the GM function in operation, or stations operating in DN mode, within communication range. The GM function then displays the acquired direction and distance information for each detected call sign on the screen.
If the DG-ID number is other than “00”, the GM function will check for partner stations set to the same DG-ID number, with the GM function turned ON, that are within communication range.
In addition to knowing who is in the service area, the APL (Automatic Position Locating) screen indicates the positions of the group members, centered on your own station (up to four are simultaneously displayed). The direction and progress of each station are displayed, and you can check each other’s position, distance, and moving direction.
You can also use GM functions to send data such as messages and images with your friends.

• When the GM function is activated, the operating band is automatically switched to the A band, and the communication mode is switched to the C4FM digital (DN) mode.
• To use the GM function, all of the members must operate on the same frequency.
• Note that when the receive DG-ID number of your transceiver is set to a DG-ID number other than “00”, received signals that do not have the same DG-ID number may not be heard.

Insert a commercially available micro-SD card into this unit to send and receive messages and images.
Usable micro-SD Memory Cards
This transceiver only supports the following capacity of micro-SD and micro- SDHD memory cards.

2GB • 4GB • 8GB • 16GB • 32GB

Not all micro-SD and micro-SDHC cards sold commercially are guaranteed to work with this product. In addition, micro-SDXC memory cards are not supported.

GM Operation

1. Tune to the frequency used by the group that you would like to communicate with.
   • If you only want to check your group location information, press and hold the [GM] key and set the send and receive DG-ID numbers to the same numbers except “00” at all the partner stations.
   • The frequency cannot be changed while the GM function is operating.
2. Press the [GM] key.
   • The callsign, distance, and direction of all stations (up to 24) within the communication range operating with the GM function on the designated frequency in DN (V/D) mode are displayed.
   • The call sign of the member who can communicate is displayed in white characters, and the distance and direction of the member from your own station are displayed.
   • Stations outside the sphere of communications callsigns are displayed in grey.
   • You can communicate in the DN mode of C4FM digital by pressing the PTT switch.

Display the APL (Automatic Position Locating) screen

The positions of up to four group stations are displayed on the APL (Automatic Position Locating) screen, centered on your own station. The direction and progress of each sta-tion is displayed, and you can check each other’s position, distance, and moving direction.

1. Touch [APL] while the GM function is active:

   • The last four stations received by the GM function are displayed on the APL screen. The displayed stations are listed on the right side of the screen with the first six characters of the callsign and the distance from your own station.

   • Display additional members by turning the DIAL knob.

   • The direction and distance of members will be displayed on the compass screen, centered on your own station. The traveling direction of your own and member stations is indicated on the compass screen.

   • The scale of the compass screen is automatically set according to the distance of the selected member station when the APL screen is displayed. Touch [
     ] or [ ] to change the scale.

   • The maximum distance at which a member’s position can be displayed on the compass screen is a radius of 1,000 km.

Disable the APL screen display

1. Touch [GM] on the display or press the [BACK] key. Return to the normal GM screen.

Confirm the location of a Group Member station in real-time

The position of the selected member can be confirmed in real-time on the compass screen. The member’s current position may be registered as the navigation destination.

Display the position of the member station on the compass screen

1. Press the [GM] key.
2. Touch the station for which you want to display location information.
3. Press the [DISP] key.
   If the GPS information screen is displayed, touch the compass display to switch to the navigation display screen.

Switch the compass screen display method
Press and hold the [ DISP ] key touch [ DISPLAY ]  [2 COMPASS ], select the screen display method (direction toward the top of the screen) from “HEADING UP” or “NORTH UP”. The default setting is “HEADING UP”.
HEADING UP: The compass circle indicates the direction ( ) you are heading. The arrow indicates the direction toward your partner’s station.
NORTH UP: Always displays the north ( ) on the top. The arrow indicates the direction you are heading.

Disable the Compass screen display

1. Press the [DISP] key.
   • You cannot update the location information of the partner stations outside of the communication range.
   • If your station or your partner stations do not set the location information manually or capture it from the GPS satellite signals, the compass display is not available.
   • GPS location information may have an error of several hundred meters depending on the surrounding environment and so on.
   • This function is a simple function using GPS satellite data. Use this as a guide for the position of your own station or partner station.

Registering the Location Information of a Partner Station

You can register the current position of the selected member, and then navigate toward that station.

1. Touch [ MEM ] in step 3 of “Display the position of the partner station on the compass screen” (page 5). [★ ], [L1], and [L2] will start blinking.
2. Touch [★], [L1] or [L2].
   • The Callsign and location information of your partner station is registered, and the Navigation starts.
   • To cancel the registration, touch [MEM] again.
   • The registered location information can be recalled later to allow navigation to that point.

GM Set Mode Function List

DP-ID LIST
Display of the DP-ID list screen
Explanation: Every C4FM digital transmits communication contains the individual ID information (Radio ID) of each transceiver. The DP-ID function uses this individual ID information.
When communicating with another transceiver, if the DP-IDs of the stations are registered in both transceivers, they can communicate even though the DG-ID numbers are different.
For details, refer to the FT3DR/DE operating Manual.

RADIO ID CHECK
Display of RADIO ID
Explanation: In the GM function, each transceiver transmits its own ID along with the call sign.
RADIO ID is a 5-digit code consisting of alphanumeric characters that are written into the transceiver during factory production.
The RADIO ID cannot be edited.
