Please note!
If the input power is higher than 15W and the power amplifier is not correctly tuned, the safety
devices will switch the PA to
STBY
. In such and event after you stop keying PTT the PA will
automatically reset and switch back to
OPR
. There is a delay of approximately 5 seconds.
5. Set
TUNE
so the FPW reads maximum.
6. Set
LOAD
so that the TUNE LCD indicator lights within 1cm to the ‘
V
’ or 1cm to the
right of the ‘
V
’ and you achieve maximum FPW.
7. Repeat tuning several times, follow steps 5 and 6.
8. Increase the input power to 73W and the output is approximately 2000W.
9. Repeat steps 5 and 6
10. Set
TUNE
to maximum output power
11. Set
LOAD
so that the
G2 Grid is less than 50mA and IA is less than 1500mA
12.
Best practice is to Adjust for Maximum RF output power with minimum current
on G2 and IA,such as G2 less than 50mA and IA less than 1500mA.
