The VERO VR-271A/471A is tough. This compact, MIL-STD-compliant transceiver delivers powerful mobile performance and such advanced features as multibple scan functions and memory names, as well as NOAAWeather 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 help make the VR-271A/471A the ideal companion for all your travels.

  • High RF Power Output (60W)
    The VR-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 VR--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 alphpnumeric characters, the green LCD display comes with a 32-step brightness control to suit all driving conditions. Also, the fornt 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 font panel for simplicity.
  • 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 frequences independently. Additionally, memory data can be edited and stored on a PC using the optional PG-5C interface cable and 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 VR-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 degrees C to +60 degrees C.
