HF2013DX-A has been design to deliver maximum output power at 50 Ohms load. To
delivermaximum output into a real load, you will need to adjust the tuning according to your
antennaimpedance.
Entering TUNE mode is done by pressing the
TUNE
button. HF2013DX-A then switches
theTRX to RTTY and sets the frequency to the corresponding segment. By changing the
values of
TUNE
and
LOAD
capacitors you tune the PA. Optimally tuned PA delivers full
output without reaching
maximum Screen current of 50mA and IA maximum current of
1500mA, however you should set G2 less than 50mA and IA less than 1500mA
.After
tuning the PA, save the settings by pressing
SET
and PA will automatically tune the
frequency of TRX to next band segment. Follow the same procedure for all bands and
segments if needed.
