for changing the
receiver gain is to compensate for changing signal strength and I think this
is best done as early as possible in the receive chain. Operating without
an AGC gives a whole new dimension to the receiver, like depth of field in
photography. Sometimes this is desireable, sometimes not.

I use a remote auto tuner so I don't need my KAT3. Used in non
