TM-271A 136-174MHz FM Transceiver TM-471A 400-470MHz Mobile Radio Vehicle Mounted for Kenwood TM271 TM471 60W Walkie Talkie

Features:
- 60W high rf power output. Despite its size, the TM-271A can provide an impressive 60 watts of RF power, with a choice of High/Low output.
- US MIL-STD 810 C/D/E/F. 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.
- 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-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 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.
- 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.
- Multiple scan functions. 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.
- 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. Thanks to the built-in TCXO, frequency stability is ±2.5ppm, while frequency drift is less than ±365Hz at -20°C to 60°C.
