Product Description
The NTX VHF-FM Series Remote Mount Transceivers are mounted using a custom ¼ ATR tray and are
operated using an AEM Tac/Com
™ control head. The NTX066 models operate over 66 to 88 MHz on the
VHF mid-band, and the NTX138 models are capable of receiving and transmitting over 138 MHz to 174 MHz
on the VHF high band.
Primary applications include airborne Search and Rescue, Law Enforcement and Forestry communications.

Features
The existing Tac/Com
™ series of control heads provide control for the transceivers.
The NTX066 range is 66.0000 to 87.9975 MHz, and the NTX138 VHF-FM models cover a frequency
range of 138.0000
– 173.9975 MHz, both in 2.5 kHz increments. A maximum of 200 channels are
available depending on the type of control head used. Depending on the model selected, the channels
can include a receive frequency and CTCSS or DCS tone, transmit frequency and CTCSS or DCS tone,
and an alphanumeric identifier.
Depending on the model selected, the transceiver provides wideband or narrowband receiver selectivity
(selectable by the control head). Wideband operation provides a bandwidth of 25 kHz and narrowband
operation provides a bandwidth of 12.5 kHz.
The NTX138 transceiver can also be selected with an optional guard receiver installed or a DF
compatible output signal. The NTX138-100 provides a DF compatible output signal.
Voice Inversion Scrambling is available as an option, depending on the selected model.
A scan function allows scanning of selected channels. Transmit power of either 1 watt or 10 watts is
selectable from the control head. Simplex and semi-duplex operations are available. DTMF encoding
and direct keyboard programming can be added using AEM’s DTE12.
