Selecting the Power Level
Description
1. Press 'Power' softkey.
2. Select desired power level from listbox.
3. Press 'ENT' to confirm.
Possible output power levels for 150 W
systems:
10 mW - 10 W - 20 W - 50 W - 100 W - 150 W
Possible output power levels for 500 W
systems:
10 mW - 20 W - 50 W – 100 W – 250 W –
500 W (when ordered with CE mark, limited to
250 W for f < 4 MHz)
Possible output power levels for 1000 W
systems:
10 mW – 50 W - 100 W – 250 W – 500 W –
1000 W (when ordered with CE mark, limited
to 250 W for f < 4 MHz)
By selecting a higher output power, the signal-
to-noise ratio at the receiver is increased,
which may extend the communication cover-
age.
The current output power during transmission
is shown in the RF Level bar graph in the cen-
tral area of the MMI. With the exception of the
constant envelope modulations F3E, F1D and
A1A, the maximum output power reached de-
pends on the audio modulation source. This is
the case especially in B8E, when only one of
the two modulation sources is present.
In B8E operation and with modulation from a
single sideband it may occur that the desired
PEP output power is not fully obtained.
10 mW denotes the output power of the
frontend. If an amplifier is connected to the
radio, there will be no RF power at the out-
put of this amplifier in the setting 10 mW.
