Next lines are for EBS (Electronic Bias Setting)
ON/OFF and for EBS level selection.
We recommend
EBS ON
. See next comment
for more details.
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. In 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.
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).
