6-1 Tuning the receiver using the rotary control

The receiver may be immediately tuned via the rotary tuning control. The free
running tuning knob is used to select receiving frequency and in memory mode
for selection of memory channel.
The tuning knob is by far the most "traditional" approach to tuning on shortwave
providing a smooth feel and the best method of user interface especially when
listening on the SSB, FAX and CW modes.
It is possible to tune the receiver through it's entire range from 30kHz to
29.99999MHz. Rotating the tuning control clockwise increases the displayed
frequency (and tunes the receiver upward), rotating the tuning control anti-
clockwise decreases the displayed frequency (and tunes the receiver
downward).
At some point you may wish to increase the speed of tuning, this is
accomplished using the [kHz] and [MHz] keys.
You will note a small underscore "_" underneath one of the frequency readout
digits. It is possible to move the underscore by pressing the [kHz] key. The
underscore will move from the underneath of the right digit (tens of Hz), second
from right (hundreds of Hz) and third from right (kHz). Pressing the [kHz] key
again returns the underscore to the right.
The position of the underscore determines the rate of tuning. On shortwave,
the receiver will tune in either 5Hz steps (10Hz resolution), 100Hz steps of 1kHz
steps.
In a similar way, you may decide to change the MHz readout using the rotary
tuning control. To accomplish this, simply press the [MHz] key. An underscore
"_" will appear on the LCD underneath the MHz digit to confirm selection. To
return to fine tuning press the [kHz] key.

6-2 Changing receive mode

There are two mode keys on the front panel located between the S-meter and
LCD, there are also seven LED indicators to show the current mode selected.
Either key may be pressed to change mode.
Any receive mode may be selected at any frequency within the receiver's
shortwave coverage.
Generally speaking the following modes will apply:
AM
Amplitude Modulation - Used by broadcast services throughout the World on
longwave, medium wave and shortwave. AM is also used by commercial
airband 108 - 137MHz (should you have the VHF converter option fitted).
For best results, you will have to experiment with the setting of AGC between
fast and slow.
