Yaesu FTM-310DE 2m/70cm FM/C4FM-Transceiver

The FTM-310DE series from Yaesu provides true dual-band operation with two independent receivers. Signals can be received simultaneously on different bands or even within the same band – including C4FM/C4FM dual receive (V/U, V/V, U/V, U/U).

The transmitter delivers up to 55 W on VHF and 50 W on UHF, with selectable power levels of 25 W or 5 W. A robust heat sink with Funnel Air Convection Conductor (FACC) ensures stable performance even during extended operation.

For clear and powerful sound, the set is equipped with the Acoustic Enhanced Speaker System (AESS): one 3 W speaker in the control head and another 3 W speaker in the main unit provide a total of 6 W audio output. The information is shown on a crisp full dot-matrix display.
