Adjustment
1 . EUIPEMENT REQUIRED
1 . SSB Radio RP output power 3-10 watts
2. Power/SWR meter
3. Power supply output 24V 25A
4. 50 ohm dummy load
2. CONNECTION
3. ADJUSTMENT
1 . Set the radio frequency on around 8Mhz, the adjustable resistor “ RS”
and adjustable capacitor “ SVC1” set middle point.
2. To key start the tuner operate, the standard operating time is from 3-8
seconds, turn left the “ SR” if it is less then 3 seconds, till the operate
time on standard time.
3. Transmit the radio, check the SWR rate by power/SWR meter, the
standard rate is less 2.0, if higher then 2.0 must to adjust the “ SVC”
until SWR less then 2.0, this adjustment may be take some times to
complete.
4. Set the radio frequency on around 3Mhz, and transmit the radio, check
the SWR rate by power/SWR meter, the standard rate is less 2.0, if
higher then 2.0 must to adjust the 66 SVC” until SWR less then 2.0, and
return the 8Mhz check again.
5. Same as action 4 set the radio frequency on 7Mhz.
6. Same as action 4 set the radio frequency on 2Mhz.
7. After above action, key start the tuner and transmit the radio, check the
SWR and output power from 2~25Mhz for each one Mhz band.
