Electronic Bias Settings (EBS) is a significant feature of this power amplifier. It automatically allows
lower plate current after pressing the PTT, regardless of whether operating CW or SSB mode, when
no RF signal is present at the input. At the moment an RF signal is applied, the bias will
automatically change to its working value.
EBS level means level of the Input power where EBS starts working. Default EBS value is 0.1 W. We
recommend turning EBS ON. A significant feature of using EBS is PA operating temperature
reduction.
NOTE: If you are not using compression in your TCVR, or you are not speaking loud enough, some
syllables can be cut off. In such a case you should turn OFF the EBS.
The next two settings allow deletion
of the manual user settings of the
amplifier tunings for a single band or
for all bands.
Settings in all segments will return to
the factory default values (for 50
Ohms).
In the next line you can define
working mode of the blower. In the
first mode speed depends on the PA
temperature (TEMP), In PTT mode
the speed increases to maximum,
and the ALLWAYS mode means
maximum speed all the time during
PA operation (recommended for DIGI
modes).
Press SAVE to write the mode to the
memory.
