Preparation
Before Start Using
● Connect DC adaptor supplied with KP-1. You
can use your own DC power supply, however
please don't apply more than 16 volts. We
strongly recommend using our products.
● Connect IN connector to your TRX with 50ohm
coax cable with SO239 on both sides.
Connect OUT connector to your ANT with 50
ohm coax cable with SO239 on both sides.
■ Operation
Select the power range the right most
(FWD10KW/REF2500W) just in case.
● Measuring FWD Power
1. Press 3 FWD button
2. For SSB Operation
Press 6 PEP button.
For AM, FM, or CW operation you don't have
to press this button.
3. If you use analog meter, select the proper
range for your transmitting power.
●
Measuring REF Power
1. Press 4 REF button
2. For SSB Operation
Press 6 PEP button.
For AM, FM, or CW operation you don't have
to pres this button.
3. If you use analog meter, select the proper
range for your transmitting power.
●
Measuring SWR
1. Press 5 SWR button.
2. Digital display shows SWR calculated by CPU.
The crossing point of needles also shows the
SWR.
●
PEP Power Measurement
KP-1 can show average power when you
operate AM, FM, or CW that has carrier.
Because SSB signals don't have carrier, the
signals change its level according to voice evel.
For this reason you need to use PEP meter to
read the power. KP-1 has a circuit that read
peak value of the power when you press 6 PEP
button. Needles swing to peak value, too.
Factory setting is 0.3second hold time. You can
set up this hold time by yourself. See P7 mode.
● Measuring Effective Power
Pressing 7 DEL button let KP-1 to calculate the
effective power. Effective power is the power
that deducts REF power from FWD power.
