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.
