Electronic Bias Settings (EBS) is one of significant feature of the power amplifier. It allows to set
low plate current after pressing the PTT regardless of whether you have CW or SSB mode, until RF
signal is no present at the input. At the moment when RF signal comes to the input of PA, bias will
automatically change to its working value.
EBS level means level of the Input power, where EBS starts working. Default EBS value is 0.2 W.
We recommend using EBS ON. Significant accompaniment of used EBS is temperature reducing.
Next two lines allow delete user
settings of antenna tunings for selected
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 case
speed depends on the temperature
(TEMP), during PTT speed increased
to maximum, ALLWAYS means
maximum speed all the time during PA
operation (recommended for DIGI
modes).
Press SAVE to write the mode to the
