INITIAL TUNE-UP
a)
Switch the ON/OFF switch to on. (There is a slight delay whilst the soft-start
activates but there is no warm-up time necessary).
NB. While the STBY/OP switch is in the STBY position your transceiver will be able
to operate as before i.e. straight into the antenna.
b)
Switch your transceiver on.
c) Pre-tune the amplifier by switching the amplifier BAND switch to the desired band
e.g. 20 for 20 metres (14MHz).
TUNING UP THE AMPLIFIER
a)
Set the TUNE and LOAD controls on the amplifier as shown on your supplied
tune-up guide sheet (at the back of this handbook).
b)
Select half-power (approx. 50 Watts) on your transceiver.
c)
Switch to TUNE or CW on the transceiver.
d)
Switch the amplifier STBY/OP switch to OP (operate), rotate the TUNE and
LOAD controls for maximum RF output using your external power meter or using
the RF-OUT meter on the amplifier.
e)
Your external Wattmeter should now show approx. 400W.
f)
Switch your transceiver to full power i.e. 100W and immediately peak the TUNE
and LOAD controls for maximum RF output.
g)
The ALC can now be used to set the desired power output level into your antenna.
h)
Switch your transceiver to the mode you require and operate your equipment as
normal.
NB. Under normal operating conditions, the plate current with full drive will rise to
between 0.75A and 1 Amp, and the grid current up to 300mA max.
With no drive, the plate standing current is normally around 100mA.
