Last Channel Recall (LCR)
If you were scanning or listening a lot to other frequencies you may want to return to your last transmission channel
by pressing a single button? Press the
LCR (6)
button to return to the last channel you used for transmission for
more than 3 seconds.
Noise Blanker
A noise blanker is a circuit to fade out or limit temporarily pulsating interferences. As the 10 m band is especially
effected by noise from electrical appliances and vehicles your unit is equipped with a corresponding function to be
engaged in AM and SSB modes.
The noise blanker is activated/deactivated by pressing
FUNC
and
NB
(5).
Simplex- and Repeater Operation
With the default settings you can start to communicate point-to-point on simpex channels. In the years of high sun-
spot activities you can reach communication distances of several 1000 kilometers. A good indicator for long
distance conditions are the repeater stations in Europe and USA. Most of the repeaters can be found in the upper
band segment just below 29.670 MHz.
Repeater settings
You can reach repeaters in Europe and – under good propagation conditions as well in USA. For repeater
operation it is necessary to shift your transmitting frequency to the uplink frequency of the repeater, while you listen
on the downlink frequency. For example you hear a repeater on 29.670 MHz. Then the suitable transmitting
frequency for this repeater is 100 kHz lower at 29.570 MHz in this example.
Activate the Repeater Shift
Press first
FUNC
and then
SHIFT
(9) in sequence.
+SHIFT
will appear in the display. Press both buttons once
more, then you obtain
–SHIFT
.
Factory default value is 600 kHz (Far East). In Europe we use 100 kHz, so you should change the setting from 600
kHz to 100 kHz.
Change Shift Value
The frequency shift can be varied between 10 and 999 kHz. Use again the sequence of
FUNC
and
SHIFT
, but then
hold the
SHIFT
-key more than 3 seconds pressed, until the display shows 600.
Now you can use the
rotary channel knob
or the
UP / DOWN
- buttons at the microphone to adjust the shift value
to the European / USA standard value 100 kHz.
Confirm the setting be pressing the
PTT
button or the
FUNC
button.
Sound Filter
The receiver comes with a switchable sound filter, what is especially useful for noisy signals, as it attenuates the
aggressive high sounds, making the sound easier to listen to. Deactivate this filter by pressing
FUNC
and
LOW
(8).
Activate/Deactivate Key Tone
Turn the unit on while pressing the transmission button (
PTT
on microphone). In this way you toggle between
activation and deactivation.

Storage and Backup of Set Data
The radio is no longer equipped with a lithium battery, but uses the low power backup technology. For this reason
data are only erased after a long time.
