SELECTING A FREQUENCY BAND

You can change the frequency bands for bands A and B.
1 Press [ ] /[ ] (1s).
• Each time you press
frequency band.
Band A: 144 ➡ 220 ➡ 430 ➡ 144 (MHz).
Band B: 430 ➡ LF/MF(AMBC) ➡ HF ➡ 50 ➡ FMBC
➡ 118 ➡ 144 ➡ VHF(174-216) ➡ 200/300
➡ 430 ➡ VHF(470-524) (MHz).
Note:
◆ 220 MHz band in Band A is used by the TH-D74A only.
Frequency ranges:
• 118 MHz: Band B 108 ~ 136 MHz
• 144 MHz: 136 ~ 174 MHz
• 220 MHz: 216 ~ 260 MHz (TH-D74A only)
• 200/300 MHz: Band B 216 ~ 410 MHz
• 430 MHz: 410 ~ 470 MHz
• LF/MF(AMBC): 0.1 ~ 1.71 MHz
• HF: 1.71 ~ 29.7 MHz
• 50: 29.7 ~ 76 MHz
• FMBC: 76 ~ 108 MHz

SELECTING THE DEMODULATION MODE

You can select the demodulation mode.
1 Press [A/B] to select an operation band.
2 Press [MODE] to select a demodulation mode.
• Each press changes the demodulation mode as follows.
Band A: FM/NFM ➡ DR (DV) ➡ (Returns to FM/NFM)
Band B: FM/NFM ➡ DR (DV) ➡ AM ➡ LSB ➡ USB ➡ CW
➡ (Returns to FM/NFM)
Note:
◆ Switching between the DV and DR modes is not possible with the
[MODE] button. (Refer to "Digital Function Menu".)
◆ The DV and DR mode cannot be selected for both band A and B
at the same time.
◆ Switching between the FM and NFM modes is not possible with
the [MODE] button. (Refer to page 16.)

SELECTING A FREQUENCY

There are 3 operating modes available to choose from: VFO
mode, Memory Channel mode, and Call Channel mode.
VFO Mode
VFO mode allows you to manually change the operating
frequency.
1 Press [VFO] to enter VFO mode.
2 Rotate the [ENC] control to select your desired operating
frequency.
• You can also select a frequency by using the [
keys.
• The default step frequency for the [ENC] control varies
according to the model and operating frequency band:
Model 144 MHz
TH-D74A 5 kHz
TH-D74E 12.5 kHz
[ ] /[ ] (1s), you cycle to the next
220 MHz 430 MHz
20 kHz 25 kHz
- 25 kHz
Note:
◆ 220 MHz band is used by the TH-D74A only.
MHz Step
To adjust the frequency by a larger amount, press [MHz] to
enter MHz mode, then rotate the [ENC] control or use the
[ ]/[ ] keys to adjust the frequency in steps of 1 MHz.
Press [MHz] again to exit MHz mode and adjust the
frequency using the normal step frequency.
Frequency Direct Entry
If the desired operating frequency is far from the current
frequency, using the keypad is the quickest way to change
the frequency.
1 Press [ENT].
The Direct Frequency Entry display appears.
2 Press the numeric keys ([0] ~ [9]) to enter your desired
frequency.
3 To set the entered frequency, press 6 digit.
• Pressing [ENT] before entering all of the digits will set
the remaining digits to 0.
Memory Channel Mode
Memory Channel mode allows you to quickly select a
frequently used frequency and related data which you have
stored in the memory channel.
1 Press [MR] to enter Memory Channel mode.
The Memory channel number appears on the display.
2 Rotate the [ENC] control to select your desired Memory
channel.
Call Channel Mode
Call Channel mode allows you to quickly select a preset
channel to allow immediate calls on that frequency. The Call
channel can be conveniently used as an emergency channel
within your group.
1 Press [CALL] to enter Call Channel mode.
"C" appears on the display.
2 Press [CALL] again, and the transceiver will return to the
previous frequency.
• The default settings are as follows.
