NAT NTX138 radios provide wide-band and narrow-band operation. The bandwidth flag
indicates the selected mode. It indicates the current modulation acceptance and
transmit deviation mode. When a character is displayed the channel is operating in
wide-band mode. When a character is displayed the channel is operating in narrow-
band mode
A typical NTX138 ID line might look like this
a01= FORESTRY

3.7.2
Display Switch Set to 'RX'
RX or Receive Frequency and Tone. This is the receive frequency of a given channel,
plus its Receive Tone (if any), displayed in the format selected previously.
A typical RX frequency might look like this:
a01= 156.875r 91
Channel RX Freq. Tone
The '=' indicates that tones are enabled from the STATUS EDIT function. The small 'r'
indicates that the data displayed is a RECEIVE frequency. If the radio is put into the
simplex mode, this will be replaced with an 's'. In SIMPLEX or DIRECT operation, the
radio's TX frequency is shifted to the RX frequency, to permit talk-around operation on
repeaters. The old data remains in the control head memory, but is not displayed.
3.7.3
Display Switch Set to 'TX'
TX or Transmit Frequency and Tone. This is the transmit frequency of a given channel,
plus its Transmit Tone (if any), in the format selected previously.
A typical TX frequency might look like this:
a01= 154.775t 100
Channel TX Freq. Tone
The '=' indicates that tones are enabled from the STATUS EDIT function. The small 't'
indicates that the data displayed is a transmit frequency. If the radio is put into the
simplex mode, this will be replaced with an 's', and the TX frequency cannot be edited.
In SIMPLEX or DIRECT operation, the radio's TX frequency is shifted to the RX
frequency, to permit talk-around operation on repeaters. The old data remains in the
control head memory, but is not displayed.
