Yaesu FTM-310DR C4FM 55W 144/430MHz Dual Band Mobile Transceiver

Yaesu FTM-310DR Dual-Band Mobile Transceiver

The Yaesu FTM-310DR is a powerful dual-band mobile transceiver designed to provide reliable and high-quality communications for amateur radio enthusiasts. It offers true dual-band operation with two independent receivers, allowing for simultaneous C4FM/C4FM receive on different bands or within the same band. With a robust power output of 55W on VHF and 50W on UHF, complemented by a Heavy Duty Heat Sink with FACC (Funnel Air Convection Conductor), this radio ensures stable and reliable performance. The FTM-310DR comes standard with advanced features for both digital and analog modes.

The FTM-310DR is equipped with Yaesu's Acoustic Enhanced Speaker System (AESS), which delivers a total of 6W of high-fidelity audio through a 3W front speaker and a 3W main-unit speaker, ensuring clear communications in any environment. Its Full Dot-Matrix display provides a high-resolution interface, allowing for efficient interpretation of the radio's versatile operating status. Features like the High-resolution Band Scope, PMG (Primary Memory Group), and MAG (Memory Auto Grouping) make operation both intuitive and advanced.

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 (SPU-1 required) 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.
