| 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.
