13. Using the power control switches increase power to 50%. Do not exceed this level
till the reflected power from the load or antenna is checked. This can be done
by selecting the REFLECTED POWER DISPLAY (RFLD). Reflected power should
not exceed 5%.
14. If the power reflected (RFLD) exceeds 5% the load or antenna, coaxial cables, and
fittings must be check for possible faults. This must be corrected before increasing
power over 50%.
15. With <5% (RFLD) power record the current levels on the ADP500 for each amplifier
stage and compare this to the test data recorded at the factory during transmitter
setup. If current levels are approximately the same as factory readings it is ok to
increase power to 100% (FWRD).
16. Return to the PA current readings on the ADP500 to verify that all the currents are
approximately the same.
17. Record these measurements in station maintenance log for future reference.
Note: This transmitter is FCC Type Certified to operate between 800 and 1200 watts
average power. This transmitter is calibrated to read 100% at the output power
level stated on the purchase order. It is assumed that this is the level stated on
the owner’s license. The FCC requires that the output power level of the
transmitter be set to 100% indicated output power. Any variation to this may
cause the transmitter to perform out of specification and not be compliant with
manufacture’s or FCC rules
