Example: If the amplifier operating levels are 42 dBmV with an operating tilt of 10 dB at
750 MHz, the operating level at the pilot frequency of 445.25 MHz would be 39 dBmV. This
was found by taking the difference in tilt between 750 MHz and 445.25 MHz (10-7=3 dB).
Then subtract the difference in tilt from the operating level (42-3=39 dBmV).
