The Yaesu FTM-310DE ASP is a mobile dual-band analog and digital transceiver for radio amateurs, engineered to deliver outstanding reception and transmission performance across the VHF (144–146 MHz) and UHF (430–440 MHz) amateur bands. Featuring two true independent receivers, it enables simultaneous dual-band reception across V/U, V/V, U/V, and U/U configurations, including dual digital C4FM/C4FM reception.
This European version comes standard with the factory-installed ASP (Audio Digital Signal Processor) unit, designed to significantly reduce background noise and enhance weak or marginal analog FM signals alongside the Super-DX function. Its acoustic layout features the 6 W AESS (Acoustic Enhanced Speaker System), combining a 3 W speaker in the front control head with another 3 W speaker in the main transceiver body, producing immersive and balanced audio inside vehicles or in fixed ham radio shack environments.
Key Advantages
- Dual Independent Receivers: Monitor two frequencies simultaneously with support for dual C4FM/C4FM digital modes and Automatic Mode Select (AMS).
- Factory-Installed ASP Audio Processing: AUTO and MANUAL modes enhance signal-to-noise ratio on critical, weak FM signals.
- 6 W AESS Acoustic System: Dual-speaker setup (front head and main body) delivers crisp, distortion-free sound.
- High-Efficiency FACC Heat Dissipation: Advanced cooling system guarantees sustained, reliable transmissions at high power levels (up to 55 W VHF / 50 W UHF).
- Integrated GPS and APRS Modem: Features a sensitive 66-channel GPS receiver and built-in APRS modem (1200/9600 bps).

Frequently Asked Questions
What advantage does the ASP version provide?
The ASP (Audio Digital Signal Processor) unit actively samples analog FM audio, suppressing background static noise and significantly improving the clarity of weak, distant signals without narrowing audio bandwidth.
Can the microphone be connected to the main body when the head is remotely mounted?
Yes. The FTM-310DE ASP includes dedicated microphone jacks on both the detachable front face and the main body chassis, giving full flexibility for vehicle installations.
