HIGH RF POWER OUTPUT[60W]The TM-271A can provide an impressive 60 watts of RF power, with a choice of High/Low output.

WEATHER ALERT/RX [US only]

 

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

US MIL-STD 810 C/D/E/F

 

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

ALPHANUMERIC LCD AND ILLUMINATED KEYPAD

 

Capable of displaying up to 6 large alphanumeric characters, the green LCD display comes with a 31-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 quicklyh accessed via menu).

DTMF MICROPHONE

 

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

HIGH-QUALITY FRONT SPEAKER

 

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

200 MEMORY CHANNELS PLUS 1 CALL-CHANNEL

 

Each of the 200memory channels can be used to store transmit and receive frequencies independently.Additionally, memory data can be edited and stored on a PC using the optional PG-5D PC interface cable and MCP-1A Memory Controls Software.

MEMORY NAME FUNCTION

 

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

MULTIPLE SCAN FUNCTIONS

 

For maximum versatility, the TM-271A offers several scan functions,including band scan,memory scan,program scan,memory 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.

CTCSS & DCS ENCODER/DECODER

 

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

HIGH FREQUENCY STABILITY

 

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