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 .
REFL. 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.
INHIBIT Indicates interruption of transmission during the tuning process of the PA. If
indicated by RED LED then PA is in STBY mode. If during a retune operations
within the same BAND then the PA will retune according to the frequency of
