NFM *
15kHz-H, 15kHz-L
* NFM mode operates with a fixed 15kHz IF bandwidth but with the selectable option
of wide audio frequency response (15kH) and narrow response (15kL).
The wider the filter, the better the audio fidelity… there is an increased chance of
adjacent channel interference with a wider IF bandwidth. The best setting will
depend upon listening conditions.
Selection of IF BW (IF bandwidth)
Press the [IF BW] key. The LCD legend displaying the IF BW will reverse to negative
image. Either rotate the main dial or press the [
←]
or
[→]
keys to select an
appropriate IF bandwidth. Press the [ENT] key when the desired IF BW is selected.

2.6 Transfer data from dial mode to memory
Press the [FREQ] key while in the VFO mode, do not hold the key… just a quick tap
will do! The current (top) frequency on the LCD will turn to a red colour. Press the
[ENT] key to transfer the receive data (frequency, receive mode, AGC, ATT, SQ
setting) to the next available memory channel of the present bank.
3 Memory mode
The AR7000 is equipped with a total of 1500 memory channels arranged as 15
memory banks 0 to 14, each containing 100 channels numbered 00 to 99. Each
memory channel can be tagged with a text ident of up to seven characters.
3.1 Display
A typical example of the memory channel mode is as follows:
{figure 45}
The memory channel mode looks similar to the VFO mode with the following
exceptions:-
1) A text ident (comment) may be shown should you choose.
{figure 45}
2) Memory channel number and memory bank number are shown as per the
illustration:-
