KENWOOD: TM-271A 144MHz FM TRANSCEIVER

Frontiers are not for the meek. It takes a rugged 4WD vehicle to meet the challenges of the wilderness. And KENWOOD's new TM-271A is built just as tough. This compact, MIL-STD-compliant transceiver delivers powerful mobile performance and such advanced features as multiple scan functions and memory names, as well as NOAA Weather Band & emergency alert reception*. On or off the road, you can always enjoy the sophistication of high-quality audio. Illuminated keys and a large LCD with adjustable green backlighting for easy operation day or night. The TM-271A is the ideal companion for all your travels.

* US only

Despite its size, the TM-271A can provide an impressive 60 watts of RF power, with a choice of High/Low output.

This transceiver is capable of receiving the NOAA Weather Band and responding to emergency transmissions such as storm warnings by emitting an audible alert tone.

Built tough to take rough treatment in its stride, the TM-271A meets the strict U.S. Department of Defense MIL-STD 810 C, D, E and the latest F environmental standards for vibration and shock.

Capable of displaying up to 6 large alphanumeric characters, the positive-type green LCD display comes with a 32-step brightness control to suit all driving conditions. Also, the front panel and microphone keypads are both illuminated for ease of use. Note that keys for only the 5 most frequently used functions are arranged on the front panel for simplicity (other functions can be quickly accessed via menu).

The TM-271A is supplied with a DTMF microphone as standard.

The large oval (2.28" x 1.38") speaker mounted in the front panel provides excellent clarity.

Each of the 200 memory channels can be used to store, transmit, and receive frequencies independently. Additionally, memory data can be edited and stored on your computer using MCP-1A Memory Control software. For details on purchasing an interface cable, consult your local dealer.

At-a-glance identification of 100 memory channels is possible with up to 6 alphanumeric characters per channel. Up to 200 channels are available if the memory name function is not used.

For maximum versatility, the TM-271A offers several scan functions, including VFO (band) scan, all memory scan, program scan, memory group scan (group scan), call scan, tone/CTCSS scan, DCS scan and priority scan, which checks a priority channel every 3 seconds. TO (Time-operated), CO (carrier-operated) and seek scan resume modes are also provided.

The built-in CTCSS and DCS encoder/decoder enables operation of the 42 CTCSS subtone frequencies and 104 DCS subtone codes.

Thanks to the built-in TCXO, frequency stability is ±2.5ppm, while frequency drift is less than ±365 Hz at -20°C ~ +60°C.
