5.1. Operation Elements
There are couple of operational elements accessible or visible on the front panel.
TUNE -
Anode capacitor for tuning, tuning of higher frequencies to "0",
lower frequencies to „100“.
LOAD - Output capacitor tunes antenna load resistance to amplifier.
Capacity is low at „100“ and high at "0" on the scale.
OFF -
You switch off the amplifier by pressing this button.
ON -
You switch on the amplifier by pressing this button.
After 3min of warm-up delay, the amplifier will be ready for operation.
OPR/STBY
„OPERATE“ sets the amplifier ready for transmit operation.
In STBY, if WAIT-LED is on or the amplifier is OFF, the amplifier
is in bypass-mode and your transceiver is directly connected to the
antenna. Maximum allowed power in bypass mode is 400 Watts!
RF OUTPUT Bar graph – shows output power .
REFLECTED POWER Bar graph – shows reflected power from the antenna.
Maximum level is 350W otherwise amplifier switches to
STANDBY mode.
Ig2 Bar graph – measures the current of the second grid from -20mA to
+80mA.
HV/IP/TUNE Bar graph – measure the anode voltage, anode currency or tuning of the
amplifier.
