3. Press PT and increase driver power to
10W
(OUTPUT power will be
abt. 500W)
Please note!
If the input power is higher than 15 W and the power amplifier is not correctly tuned, the safety devices
will switch to STBY.
After switching the amplifier to PTT, the amplifier will automatically reset and switch back to OPR mode
after approximately 2 seconds.
4.
Adjustment process
: Move
TUNE
left or right until maximum of
FWD
power reached.
Then move
LOAD
carefully so that Ig2
Screen
current will be not higher than 20mA.
Optimum means maximum FWD power and Screen between 10 – 20mA
for the full
power output. Repeat more times.
After this procedure the amplifier is tuned correctly and ready to give 1500W output power in all
operation modes. At optimal tuning and full output power a positive 50mA current goes through the
second grid.
Please note: Should the amplifier demonstrate any malfunctions during
tuning or should it not behave in accordance witch the description, interrupt
the tuning procedure immediately and check the amplifier!
Be sure to have not done any mistakes in choosing bands or TUNE/LOAD
values!
Be sure that SWR is not higher than 1:2 and input power is LOW!
After excluding human mistakes you will be able to work for long time with
this amplifier!
