7. Continue to slowly raise the FWD power until you reach 100% (equivalent to
30W after the output BPF). Be careful to make small increases in the value of
POWER as you approach 100% output power level.
The chart below shows typical 30W TX power levels and performance at CH27
(551MHz) with a 6-pole BPF and couplers connected as shown in the
Interconnect Diagram of section 4.
The Chart below shows typical 30W TX power levels and performance at
different frequencies across the UHF spectrum.
