Operating and installation instructions
RF-KIT Power Amplifier RF2K-S
Deviating from the antenna registered as standard for a respective
band (see 5.2.3 Antennas), also an another antenna can be choosen by
touching switching area Actually Choosen Antenna.
Indication area Actually Choosen Antenna displays the standard antenna
for the current frequency in
green
and each other antenna in
red
.
When changing the frequency, the antenna tuner always uses the setting
values determined for the standard antenna first.
If an alternative antenna shall be used for the selected frequency range,
choose a corresponding antenna by touching switching area Actually
Choosen Antenna.
Therefore up to 4 different setups can be stored for the same tuning seg-
ment and be called up, according to the number of antennas connected.
6.2 Input Power for tuning
For a automatic tuning process of the antenna tuner, the input power must
be in the range between 4 W (min.) and 39 W (max.).
Outside this power range, the
switching area
Tune button is not activated
and remains
dark blue
(= tuner inactive)).
►
Adjust input power between minimal 4 W and maximal 39 W.
►
Select CW or FM mode on your exciter.
►
Start to send.
►
Tap at switching area Tuner Reset, to reset values for L and C
to “zero“.
►
Tuning of L by tapping at switching areas
>
Increase value fine (+0,08 uH)
>>
Increase value coarse (+0,80 uH)
<
Decrease value fine (-0,08 uH)
<<
Decrease value coarse (-0,80 uH)
►
Tuning of C by tapping at switching areas
>
Increase value fine (+5 pF)
>>
Increase value coarse (+50 pF)
<
Decrease value fine (-5 pF)
<<
Decrease value coarse (-50 pF)
The results of the tuning can be seen by the value for SWR displayed in
indication area SWR.
Finish manual tuning process:
►
Stop to send.
►
Tap at switching area Store to save the settings for the current
antenna / frequency combination.
Switching area Store flashes 2x briefly to indicate the storing process.
6.3 Manual tuning
To manually detect and save a tuner configuration and settings for a given
antenna / frequency combination, proceed as follows:
►
Tap at switching area Tuner Mode, until “MAN“ is displayed in
red
.
At manual tuning the antenna tuner can be configured both as high pass
and low pass.
►
Tap (repeated) at switching area K for tuner configuration as a
high pass filter:
►
Tap (repeated) at switching area K for tuner configuration as a
low pass filter:
