SELECTING A POSITION COMMENT

Enter Menu mode and access Menu 607.

The APRS data which you transmit always includes one of the

15 predetermined position comments. Select an appropriate

comment depending on your situation.

The selectable comments are listed below:

[Off Duty] [Enroute] [In Service] [Returning] [Committed] [Special]

[PRIORITY] [CUSTOM 0 ~ CUSTOM 6] [EMERGENCY!]

• If you select “Emergency!”, a conﬁ rmation message appears. Press

the Tuning control again.

ATTENTION: When it is unnecessary, never “EMERGENCY!”. When an

emergency signal is received using APRS, the Emergency Alarm on all

stations will sound.

STORING STATUS TEXT

Enter Menu mode and access Menu 608.

■ Text <TEXT>

Status text is another comment to transmit with position

data. Unlike a position comment, you can make any desired

comment using a maximum of 42 alphanumeric characters.

This transceiver has 5 memory channels for preprogramming.

1 Select a status text number.

• Press [USE] to mark the currently used status text with [ ].

2 Enter your status text.

■ Text Transmit Frequency <TX RATE>

Select the frequency on which to transmit the status text

when the APRS beacon is transmitted. You can select [OFF],

or [1/1] ~ [1/8] (APRS only).

• 1/X means the status text will be transmitted X number of times.

QSY FUNCTION

The QSY function uses AFRS (Automatic Frequency Reporting

System) to report a frequency on which voice communications

can be established. A station using the QSY function embeds

the frequency information in a position beacon transmission.

A receiving station of this information can change frequency,

or QSY, over to the reported voice frequency to begin voice

communication by the select of [TUNE].

Transmitting QSY Information

A properly conﬁ gured functioning TM-D710G QSY station can

automatically embed the voice frequency from the non-data band

to the beginning of status text. This is the mechanism used for

automatically transmitting the frequency information.

The format of the transmitted frequency is FFF.FFF MHz.

So, for example, if at the time of a beacon transmission, the

non-data band has a frequency of 446.100 MHz selected, then

the frequency of “446.100MHz” gets embedded to the beginning

of the status text. If you conﬁ gure in any of Statuses 1 through 4

the frequency of “446.100MHz” at the beginning of the status text

messages, then this ﬁ xed frequency will be transmitted as QSY

information along with the beacon transmission. In addition to

frequencies, there are ﬁ elds where you can send other settings

such as Wide/Narrow, Tone/CTCSS/DCS, Shift (+/-), and Offset

frequency simply by -leaving one space between each value.

Therefore, other information besides just a frequency can be

sent.

QSY Information Format:

(Insert one space after the frequency before entering Wide/

Narrow, Tone/CTCSS/DCS and Shift/Offset.)

• “T079”: An upper case “T” indicates Wide. Tone frequency of 79.7

Hz. (Encoding)

• “t079”: A lower case “t” indicates Narrow. Tone frequency of 79.7 Hz.

(Encoding)

• “tOFF”: A lower case “t” indicates Narrow. Tone = OFF (Without any

tone Encoding or Decoding.)

• “C079”: An upper case “C” indicates Wide. CTCSS frequency of 79.7

Hz. (Encoding/ Decoding)

• “c079”: A lower case “c” indicates Narrow. CTCSS frequency of 79.7

Hz. (Encoding/ Decoding)

• “D023”: An upper case “D” indicates Wide. DCS code of 023.

(Encoding/ Decoding)

• “d023”: A lower case “d” indicates Narrow. DCS code of 023.

(Encoding/ Decoding)

• “+” : Plus Shift (A default offset frequency is applied.)

• “–” : Minus Shift (A default offset frequency is applied.)

• “+500” : Plus Shift, 5 MHz Offset

• “–060”: Minus Shift, 600 kHz Offset

The value of the Offset shall be a 3-digit number. (x 10 kHz/ 50

kHz step)
