TM-271E FM transceiver (144MHz) is blazing a
trail for the future of mobile communications.



All-Terrain Performance
All-Terrain Performance
Frontiers are not for the meek. It takes a rugged 4WD vehicle to meet the challenges of the wilderness. And Kenwood's new TM-271E is built just as tough. This compact, MIL-STD-compliant transceiver delivers powerful mobile performance and such advanced features as multiple scan functions, memory names, and external TNC connectivity for packet communications. But on or off the road, you can always enjoy the sophistication of high-quality audio, illuminated keys and a large LCD with adjustable cool-green backlighting for simple operation, day and night. The TM-271E is the ideal companion for all your travels.

HIGH RF POWER OUTPUT Åi60WÅj

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

US MIL-STD 810 C/D/E/F & EUROPE’S E-MARK

Built tough to take rough treatment in its stride, the TM-271E meets the strict U.S. Department of Defense MIL-STD 810 C, D, E & F environmental standards in categories such as Vibration and Shock. It is also certified compliant with EU Directive 95/54/EC (Automotive-EMC). COMPLIANT LOGO

ALPHANUMERIC LCD AND ILLUMINATED KEYPAD


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).

DTMF MICROPHONE

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

HIGH-QUALITY FRONT SPEAKER

The large oval (58mm x 35mm) speaker mounted in the front panel provides excellent clarity.

MULTIPLE SCAN FUNCTIONS

For maximum versatility, the TM-271E 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.

200 MEMORY CHANNELS PLUS 1 CALL-CHANNEL

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. MCP-1A

MEMORY NAME FUNCTION

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.

CTCSS & DCS ENCODER/DECODER

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

HIGH FREQUENCY STABILITY

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

1200/9600BPS HIGH-SPEEDDATA COMMUNICATIONS

When hooked up to a TNC, you can make use of either standard 1200bps or high-speed 9600bps packet communications. 1200/9600BPS HIGH-SPEEDDATA COMMUNICATIONS
