i.e. for 25 kHz type [2] [5] [ENT]. Acceptable step size is anything between 0.01 kHz
(10 Hz) and 1000 kHz (1 MHz). The back space key [

←

] will act as delete key if a

mistake is made.

When AUTO MODE is selected, the step size is selected automatically by the
AR7000 CPU appropriate to the market area, this is taken from a detailed bandplan
entered into the AR7000 during manufacture.

2.4 Selection of receive mode

The AR7000 provides the following receive modes:-

AUT: When auto mode is selected, the AR7000 automatically selects the
appropriate step size, IF BW and receive mode on your behalf using its factory pre-
programmed band plan data.

USB: Upper Side Band, used by radio amateurs, prolific on the HF bands. Also
used by commercial HF utility stations.

LSB: Lower Side Band, used by radio amateurs below 10 MHz.

CW1: CW with a 400Hz beat tone, Continuous Wave = Morse code.
CW2: CW with a 600Hz beat tone
CW3: CW with an 800Hz beat tone

AM: Amplitude Modulation, LW, MW & HF broadcast, airband.

NFM: Narrow band Frequency Modulation, most point to point communications on
VHF/UHF.

WFM: Wide band Frequency Modulation, Band-II VHF, TV

Selection of Receive Mode
Press the [MODE] key. The LCD legend displaying the receive mode will reverse to
a negative image.

{figure 41}

Either rotate the main dial or press the [

←]

or

[→]

keys which carousel through the

receive modes as per diagram. Press [ENT] when the desired receive mode is
displayed.

2.5 Selection of IF bandwidth

The AR7000 can be operated using the various bandwidths in accordance with the
table below:-
