  • 2 m (TM-255E) all-mode operation
  • 101 memory channels
  • DDS with "fuzzy logic" control
  • TF-SET (TX frequency set) function
  • DTSS selective calling with pager function
  • 1200/9600 bps packet terminal

TM-255E in detail:

    40-watt output
    Maximum RF output is 40 watts (TM-255E). A HI/LO switch enables power reduction to 5 watts.

    100 multi-function memory channels plus 1 call channel
    Facilitating on-the-move operation are 101 memory channels, plus memory shift and memory scroll functions. Channels 50~98 are capable of storing transmit and receive frequencies independently.

    Multi-scan functions
    There is a choice of full band and programme band scans, memory scan with memory channel lock-out, MHz scan and V/M/C scan. The operator can also select time-operated or carrier-operated scan stop modes, and adjust scan speed.

    Data connector for 1200/9600 bps packet
    A 6-pin mini DIN connector lets the operator enjoy either standard 1200 bps or 9600 bps high-speed packet communications with a TNC.

    DDS (Direct Digital Synthesizer) with fuzzy control
    We've incorporated "fuzzy logic" control circuitry, so the main encoder tunes smoothly from fine (5 Hz step) to fast forward (200 Hz step).

    Twin tuning dials
    In addition to the smooth-action dial on the main unit, there is a click-type dial on the detachable panel for convenient mobile use.

    Dual-menu system
    The user-friendly menus -- which are also accessible via the supplied microphone -- are divided into two groups (A & B) depending on frequency of use.

    Interference reduction
    AIP (Advanced Intercept Point) circuitry allows the operator to choose either high sensitivity or a high intercept point to suit conditions. IF-SHIFT (SSB, CW) and a pulse noise blanker further improve RX performance.

    TF-SET is available when the receive frequency is locked, so the operator can avoid losing a targeted station.

    Multi-function microphone
    The supplied remote-control microphone has 4 programmable function keys -- ideal for mobile operation.

Other Features:

  • Built-in DTSS selective calling with pager
  • Semi break-in circuit (CW) 
  • Automatic mic gain control circuit (SSB)
  • Built-in TCXO (temperature-compensated crystal oscillator)
  • Tone alert system with elapsed time indicator
  • S-meter squelch
  • All-mode squelch
  • Built-in CTCSS encoder & optional decoder (TSU-8)
  • Auto power-off & time-out timer

Dimensions (W x H x D):

  • 180 x 60 x 215.5 mm (7.0 x 2.4 x 8.5 in.)
