FEATURES

  • VHF/AM/FM Modular Communications System
  • Transportable AM and FM base station
  • Capable of operating simultaneously on any 25 kHz VHF/AM aeronautical band frequency
  • Power can be external 120 VAC, 12 VDC, or 24 VDC
  • Both transceiver modules utilize state of the art microprocessor controlled frequency synthesis techniques to provide communications on every currently available channel
  • Mounted into a rugged transportable case with protective covers (front and rear) into which the accessories (microphone, power cables, antenna cable, etc.) can be stored
  • Intended for temporary, emergency or backup operation in a fixed environment
  • The FM transceiver incorporated is the Technisonic TFM-138B
    • Can be operated in the Direct Entry or Simplex mode by simply keying in the desired operation frequency, or can function without restriction on any split frequency pair within the band
    • 120 preset memory positions each of which is capable of storing a receive frequency, a transmit frequency, a separate CTCSS tone for each receive and transmit frequency and an alpha numeric identifier for each channel
    • Allows for DPL or DCS coded squelch operation
    • Allows either 25 kHz wide band or 12.5 kHz narrow band operation on any or all of 120 preset channels
    • Data can be easily entered into any of the preset non-volatile memory positions for both main and guard channels via the front panel keyboard
    • Information stored in memory is available for instant recall by keypad entry, or by pressing the UP or DOWN button which allows the operator to scroll through all preset channels
    • Features a synthesized two channel guard, receiver, a DTMF encoder for signaling during transmit, and a scan function which will scan any or all of the frequencies stored in the preset memory positions
  • The VHF/AM transceiver incorporated is the Technisonic high-performance 91-DE
    • Allows the operator to store up to 10 channels in non-volatile memory which are displayed on a front panel liquid crystal display, and then easily recall, seek, or scan them
    • Receive only channels to prevent unauthorized transmission as well as a 90 second time out feature are easily programmed via the front panel 12 button key pad
    • The highly sensitive and selective receiver provides for superior long distance communication
    • 35 dB Rx and Tx audio compressor maintains constant audio level and modulation
    • User adjustable squelch and external headset jack are conveniently located on the front panel
    • Noise cancelling dynamic microphone (included) provides for clear audio even in a high noise environment

In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.
