Kenwood TM-201A 2M FM Transceiver

Manufactured: 1983-198x (Discontinued)

FEATURES

Compact, slim transceiver for easy mobility

  • Coaxial connector with cable greatly reduces effective depth when connecting an antenna cable
  • External speaker system allows installation in any place
  • Remote frequency control unit IFC-lOl extends your operation a flexibility

Microcomputer provides mufti-frequency control functions

  • Five channel memories plus COM channel.
  • ALERT function monitors memory channel 1 (Ml)
  • Memory scan operation (MSI from memory channels 1 through 5.
  • Programmable scan within the selected frequency range.
  • 1 MHz Step-up function (MHz).
  • VFO A in 5 kHz (25 kHz; for European and British versions) steps, VFO 6 in 5 kHz steps
  • Beeper indicates each of 7 modes.

Dual function keyboard facilitates memory recall (MRI

High reliability by using PC boards for each unit; high sensitivity (12 dB SINAD 0.22 uV) front-end using GaAs FETs

Quality sound for transmission and reception

  • External communications speaker, 77 mm in dia., supplied.
  • Maximum 3% modulation distortion ensures good quality transmit signal

HI/LOW switch controls output power

Repeater operation

  • COM system facilitates access to repeaters with the TU-3 or TU-3A tone unit" (option) installed.
  • The TU-3 or TU-3A 2nd tone frequency (one of 37 frequencies selectabiel interconnected with the TX OFFSET system enables access to a repeater
  • The REV switch monitors direct signal.

Extended frequency range* Covers 142.0-148.995 MHz in 5 kHz steps
