Yaesu FTM-310DR C4FM/FM Dual Band Mobile Transceiver

C4FM Digital/FM 55W/50W 144/430MHz Dual Band Mobile Transceiver with Super-DX + ASP and AESS Dual Speakers

The FTM-310DR series consists of the FTM-310DR ASP and FTM-310DR which shares the core feature set of the FTM- 310DR ASP. However, the FTM-310DR requires the optional SPU-1 board for ASP (Audio Digital Signal Processing) operation. *

The FTM-310DR series provides true dual band operation with two different receivers on different bands or within the same band including C4FM/C4FM simultaneous receive (V/U, V/V, U/V, U/U). The power output is 55W on VHF and 50W on UHF (55W/50W, 25W,5W are selectable). Heavy Duty Heat Sink with FACC (Funnel Air Convection Conductor) ensures stable and reliable transmit power.

The total audio output is 6W, which is generated by AESS (Acoustic Enhanced Speaker System) consists of the the 3W front speaker inside the control-head and the 3W main-unit speaker. By varying the phase, output balance and frequency characteristics of the front and main-unit speaker output, AESS achieves clear and high-fidelity audio while ensuring reliable communications even in outdoor or noisy environments.**

Full Dot-Matrix display conveys information with clarity and precision, enabling users to interpret the versatile operating status efficiently.

Features of FTM-310DR Series:

C4FM Digital Mode

C4FM Digital is the standard mode for professional communication devices and has excellent audio quality (BER: Bit Error Rate Characteristics) compared with GMSK digital. By adding YAESU’s original error correction technology, the FTM- 310DR series has achieved comprehensive high-grade communications.

Super-DX + ASP (Audio Digital Signal Processor)

In both C4FM digital and FM analog modes, the sensitivity of the RF amplifier can be increased by activating the Super-DX function. When operating in FM analog mode, the ASP can be activated in addition to the Super-DX. ASP AUTO/ MANUAL modes are selectable. In ASP AUTO mode, Super-DX is always turned on and ASP automatically activates when the transceiver detects weak signals in FM analog mode. In ASP MANUAL mode, Super-DX and ASP can be manually switched on and off each time [S-DX] key is briefly pressed.

PMG (Primary Memory Group)

Up to 5 VFO or Memory Channel frequencies can be assigned to the PMG and monitored using two different receivers. The reception status of the PMG channels is displayed in real time with a bar graph on the PMG screen. AUTO or MANUAL mode is selectable. AUTO mode monitors all PMG channels and up to two channels can be simultaneously heard. Transmit is automatically moved to the received channel. MANUAL mode always monitors the manually selected channel and transmit also stays on that channel. The signal received on the other channel is also shown on the screen and the audio can be heard.

MAG (Memory Auto Grouping)

Memory channels can be automatically grouped and recalled for each band. In “My Group(M-GRP)”, any memory channels can be registered according to the user’s preference regardless of band.

CFL (Customized Function List)

Up to 9 frequently used functions from the 127 Menus can be registered and then easily selected.

High-resolution Band Scope

Dual receive and Scope operation display is switchable each time the [BAND(SCOPE)] key is pressed and held. Up to 47 channels can be displayed with the Scope operation. By rotating the left DIAL knob, the frequency range can be centered and the signal at the center marker is received. By rotating the right DIAL knob, the marker can be moved across the display and the signal at the market is received. Transmission can be performed at the frequency of the marker position at any time.

FM Friendly Digital using AMS(Automatic Mode Select)

AMS (Automatic Mode Select) automatically determines whether the receiving signal is C4FM Digital or FM analog and sets the receiver to the appropriate mode.

DG-ID (Digital Group ID) and GM (Group Monitor)

DG-ID function allows using two-digit ID numbers (00 – 99) to communicate only with specific group members who set the same frequency and DG-ID number in advance. GM (Group Monitor) function can be utilized to automatically monitor when group member stations with the same DG-ID number are operating within communication range.

Other practical features of the FTM-310DR series are:

• High-Sensitivity 66 channel GPS Receiver
• 1200/ 9600bps APRS® Data Communication
• Fully Supports the WiRES-X operation
• Wide-range receiver coverage from 108MHz to 550MHz both on MAIN/SUB bands
• Bluetooth® hands-free operation is available by installing the optional BU-5 board
• Flexible angle adjustment of the control-head by attaching the optional swing-head kit SJMK-500
• Control-Head with Microphone jack in addition to the microphone connections on the front of the main unit

*Super-DX is available with the FTM-310DR without the SPU-1 board.
** The main-unit speaker will not sound when the ASP function is in use but 3W front speaker positioned inside the front head ensures clear and powerful audio.
