CRS FIRST AND SECOND IF AMP A3400/CRS THIRD IF AMP AND LIMITER A3500. (CONT)

The third IF amplifier increases signal strength sufficiently to drive the limiter. The limiter clips the

upper and lower peaks of the if to maintain the constant amplitude required by the Travis-type

discriminator in the Hunt Discriminator A3600. Filter FL3005 provides additional attenuation of all

signals other than the if input.

HUNT DISCRIMINATOR A3600

If signals with a frequency of approximately 5.60 or 5.65 MHz are applied to the Buffer Amplifier

A3600, which prevents loading down the limiter. The buffer amplifier's output is then fed to the Travis-

type hunt discriminator.
