The Yaesu FT-3185E ASP is a single-band VHF mobile transceiver configured for vehicle or base station operations. It delivers a maximum transmit power of 85W, utilizing a fanless massive heatsink to maintain stable radio frequency (RF) output without mechanical cooling noise. For versatile power management, output levels are selectable between 85W, 50W, 20W, and 5W depending on close-range or long-distance communication requirements.
This transceiver incorporates a Super-DX function designed to elevate receiver sensitivity and improve weak signal tracking. Pressing the Super-DX key activates the built-in ASP (Audio Digital Signal Processing Unit), which works inline to refine weak signal audio quality and extend reliable communication ranges. The unit runs on a standard 13.8V DC power supply (±15%) and operates stably across a technical temperature range of -20°C to +60°C.
Features
- Primary Memory Group (PMG) tracking for up to 5 VFO or Memory Channel frequencies with real-time bar graph display status.
- Selectable PMG operating modes: AUTO mode automatically shifts transmission to the active received channel, while MANUAL mode locks operations to a chosen frequency.
- Customized Function List (CFL) allowing registration and quick recall of up to 9 frequently used menu items out of 44 available options.
- Large-capacity internal memory structure featuring 221 channels with 6-character alphanumeric label compatibility.
- Supplied DTMF microphone enabling direct keypad entry of operational frequencies.
- Versatile signal scanning capabilities including Preferential Memory Scan, VFO Scan, and Priority Channel Scan (Dual Watch).
- Built-in CTCSS and DCS encoder/decoder sub-audible tone signaling systems.
- Integrated power-preservation and safety settings: Automatic Power-Off (APO), Time-Out Timer (TOT), and Busy Channel Lock-out (BCLO).
