YAESU FTM-310DR ASP C4FM/FM Dual Band Mobile Transceiver – 144/430MHz, 55W VHF / 50W UHF, Digital + Analog

The Yaesu FTM-310DR is a professional-grade dual band digital car mount radio featuring C4FM and FM modes, operating on 144/430MHz frequencies with 55W output power. This advanced UV dual band transceiver includes integrated GPS positioning for amateur radio, emergency communications, and fleet operations.

Description:
– The FTM-310DR series has true dual band operation capability: two independent receivers can work simultaneously in different frequency bands or within the same frequency band, supporting simultaneous reception of C4FM/C4FM (V/U, V/V, U/V, U/U). The transmission power is VHF 55W, UHF 50W, and can be switched between three levels: 55W/50W, 25W, and 5W. The heavy-duty heat sink is equipped with FACC (funnel-shaped air convection conductor) to ensure that the transmission power can work stably and reliably for a long time.
– The total audio output power is 6W, implemented by AESS (Acoustic Enhanced Speaker System): the front panel is equipped with a built-in 3W front speaker and a 3W host speaker. By adjusting the phase, output balance, and frequency characteristics of the front and rear speakers, AESS can still provide clear and high fidelity voice communication in outdoor or noisy environments.
– The full dot matrix display provides clear and accurate information, helping users efficiently grasp diverse operating states.

C4FM Digital Mode:
– C4FM is the standard format for professional communication equipment, which has better audio quality (BER: bit error rate characteristics) compared to GMSK. C4FM integrates original error correction technology for YAESU to comprehensively achieve high-quality communication.

Super-DX + ASP (Audio Digital Signal Processor):
– Super-DX can be turned on in both C4FM digital and FM analog modes to improve the sensitivity of the RF amplifier; In FM simulation mode, in addition to Super DX, ASP can also be enabled. ASP provides two modes of AUTO/MANUAL:
AUTO mode: Super DX is normally open, and ASP is automatically activated when a weak signal is detected.
MANUA mode: Press the [S-DX] key to manually switch between Super DX and ASP switches.
– Note: When ASP is enabled, the host speaker is muted, and the 3W front speaker on the control panel can still output clear and powerful audio.

PMG (Primary Memory Group):
– Up to 5 VFO or storage channel frequencies can be stored in PMG and monitored through two independent receivers. The PMG screen displays the reception status of each channel in real-time using a bar chart. You can choose between AUTO or MANUAL mode. AUTO mode automatically polls all PMG channels, can simultaneously monitor up to two channels, and supports two channels to play sound; The transmission automatically jumps to the current receiving channel. The MANUAL mode always monitors the manually selected channel and locks the transmission to that channel; The signal from another channel is displayed on the screen and can be monitored for audio.

MAG (Memory Automatic Grouping):
– Storage channels can be automatically grouped by frequency band, or registered across frequency bands according to personal needs in “My Group (M-GRP)”.

CFL (Custom Function List):
– You can register the 9 most commonly used functions from the 127 menus and enable one click access.

High Resolution Frequency Band Oscilloscope:
– Long press the [BAND] (SCOPE) key to switch between dual reception and spectrum display; The spectrum displays a maximum of 47 channels. Rotate the left knob to shift the frequency range, and the signal at the center mark will be automatically received; Rotate the knob on the right to move the marker, and you can listen to the signal at the marker in
real time and transmit it at the marker frequency at any time.

FM Friendly Digital Function – AMS (Automatic Mode Selection):
– AMS automatically determines whether the received signal is C4FM digital or FM analog, and switches to the corresponding mode.

DG-ID (Digital Group ID) and GM (Group Monitoring):
– DG-ID implements group calling with the same frequency and ID using two digit IDs (00-99); The GM function can automatically monitor the communication status with DG-ID members within the communication range.

Other Functions:
– High sensitivity 66 channel GPS receiver
– 1200/9600bps APRS data communication
