REPEA TER – 1 REPEA TER ACCESS Most repeaters use a receive and transmit frequency pair with a standard or non-standard offset (odd-split). In addition, some repeaters must receive a tone from the transceiver in order to gain access to the repeater.
REPEA TER – 2 Q Selecting a T one Frequency To select the tone frequency required to access your desired repeater: 1 Turn the Tone function On. 2 Press [F], [TONE] . • The current Tone frequency appears on the display and blinks. The default frequency is 88.
REPEA TER – 3 TRANSMITTING A 1750 Hz TONE Most repeaters in Europe require that a transceiver transmit a 1750 Hz tone. On a TH-D72E, simply pressing [CALL] will transmit this tone. It is also possible to program [1750] on the front panel as a [CALL] key for transmitting the 1750 Hz tone.
MEMORY CH – 1 MEMORY CHANNELS In Memory channels, you can store frequencies and related data that you often use. Then you need not reprogram the data every time. You can quickly recall a programmed channel by simple operation. A total of 1000 Memory channels are available for bands A and B.
MEMORY CH – 2 STORING ODD-SPLIT REPEA TER FREQUENCIES Some repeaters use a receive and transmit frequency pair with a non-standard offset. To access those repeaters, store two separate frequencies in a memory channel. You can then operate on those repeaters without changing the offset frequency you stored in the menu.
MEMORY CH – 3 NAMING A MEMORY CHANNEL You can name Memory channels using up to 8 characters. When you recall a named Memory channel, its name appears on the display. Names can be call signs, repeater names, cities, people, etc. 1 Press [MR] to enter Memory Recall mode.
MEMORY CH – 4 Key Name [KEY] [F], [KEY] [KEY] (1s) MR mode While T ransmitting [KEY] + Power ON [PTT] Transmission – X TX/RX X – [LAMP] Backlight ON Backlight ON continuously Backlight ON Backli.
SCAN Scan is a useful feature for hands-off monitoring of your favorite frequencies. Becoming comfortable with all types of Scan will increase your operating efficiency. This transceiver provides the following types of scans: Scan Type Scan Range VFO Scan Scans all frequencies on the current band.
SCAN – 2 VFO SCAN VFO Scan monitors all frequencies tunable on the band, using the current frequency step size. 1 Select your desired band. 2 Press [VFO] (1s) . • Scan starts at the current frequency. • The 1 MHz decimal point blinks while scanning is in progress.
SCAN – 3 Q Naming a Memory Group You can name Memory group using up to 8 characters. 1 Press [MHz] , then press [ ]/[ ] or rotate the Tuning control to select a channel in your desired group. 2 Enter Menu mode and access Menu 144. 3 Enter your desired name for the group.
SCAN – 4 PROGRAM SCAN Program Scan is identical to VFO Scan except that you select a frequency range for the scan. Q Setting Scan Limits You can store up to 10 scan ranges in Memory channels L0/U0 to L9/U9. 1 Press [VFO] . 2 Select your desired band.
CTCSS/ DCS/ CROSS TONE – 1 CTCSS/ DCS/ CROSS TONE CTCSS You may sometimes want to hear calls only from specific persons. The Continuous Tone Coded Squelch System (CTCSS) allows you to ignore (not hear) unwanted calls from other persons who are using the same frequency.
CTCSS/ DCS/ CROSS TONE – 2 CTCSS FREQUENCY SCAN This function scans through all CTCSS frequencies to identify the incoming CTCSS frequency on a received signal. You may find this useful when you cannot recall the CTCSS frequency that the other persons in your group are using.
CTCSS/ DCS/ CROSS TONE – 3 DCS CODE SCAN This function scans through all DCS codes to identify the incoming DCS code on a received signal. You may find it useful when you cannot recall the DCS code that the other persons in your group are using. 1 Press [TONE] 3 times to activate the DCS function.
DUAL TONE MULTI-FREQUENCY (DTMF) The keys on the keypad function as DTMF keys; the 12 keys found on a push-button telephone plus 4 additional keys (A, B, C, D). This transceiver provides 10 dedicated memory channels. You can store a DTMF code with up to 16 digits.
DTMF – 2 Q T ransmitting Stored DTMF Codes 1 Press and hold [PTT] . 2 While transmitting, press [MENU]. • The last called DTMF Memory channel number and name appears on the display. If no name has been saved for the channel, the DTMF code appears.
EchoLink ® What is EchoLink ? EchoLink allows you to communicate with other amateur radio stations over the internet, using VoIP (voice-over-IP) technology. The EchoLink software program allows worldwide connections to be made between stations, or from computer to station, greatly enhancing your communications capabilities.
EchoLink – 2 Q Selecting a T ransmit Speed Some EhoLink node station may not respond correctly if a DTMF code is transmitted at fast speed. If this happens, change the DTMF code transmission speed; the default is 100 msec. 1 Enter Menu mode and access Menu 171.
