Hello TE:

Yep I sure do.

Not only do they need a good tracking AGC, but a variable audio level
control that would adjust the audio levels from all stations the same or
at least with in a few dB of each other. A Automatic Level Amplifier
can't be to hard to run down off the net.

The Sonic Cushion does a very good job with all this. Worth the parts
and time to experiment with. With the rigs DSP (Digital Signal
Processing) Noise Reduction, digital filters, attenuator, and nose
blanker, the addition of a sonic cushion will also help, I think.

By being able to rotate the beam away from atmospheric noise and
unwanted stations is also a big help. The use of the beams rejection and
rigs attenuator and filters, its amazing what unwanted stations signals
can be put in the noise. Even loud and strong local signals!

The Moonraker 4 has a 45 dB null 110 degree's off the front of the beam,
by turning the beam null to the unwanted signals direction will drop em
like fly's.

Jay... good explanation. Do you feel the audio AGC in todays radio has
been improved to the point where you don't need such a device?
