AFC (Automatic Frequency Control)
The
Automatic Frequency Control
function is activated by pressing the
AFC
button. It will keep the receiver tuned to the selected station if the transmitter
frequency drifts.
While this function is active, the receiver will periodically check the received
signal and correct the frequency in approximately five-second intervals.
This facility is not recommended for LSB and USB modes with voice
modulation, and it is not supported for the optional wide-FM (FMW) mode.
Frequency Stepping
The
Frequency Stepping
facility makes it possible to specify an
arbitrary frequency step size. To change the step size, click on
the associated display and enter the required value (from 1 Hz to
1 MHz). You can also use the up and down buttons on the right
of the display, to select from commonly used step sizes. For
convenience, you can also use the small slider between the two
buttons.
When the step size is selected, you can step up or down from the currently
displayed frequency using the left or right arrow buttons under the step size
display. The double-arrow buttons further down will cause stepping by a step
size ten times larger. Stepping can also be done using the keyboard
Pg Up
or
Pg Down
keys.
For example, if you wish to browse the AM broadcast band (approx. 530 to
1620 kHz), set the step size to 10 kHz (for North and South America) or 9 kHz
(for the rest of the world), which is the channel separation for AM broadcast
stations.
Tune manually to any station first, then step up or down to browse the band.
To browse the shortwave broadcast stations (2.3 to 30 MHz), a step size of
5 kHz works well.
