[R-390] AGC Questions

[Flowertime01 at wmconnect.com]

Dennis,

If you have a 16K filter bad, the side effect could be a bad AGC.

The output of all the filters is tied together on one side to the AGC line.
The other side of the filter outputs are switched through the band switch.
The unused filters are shorted when not in use.

A known side problem with bad filters is the AGC acts funny. This depends
on exactly what goes wrong in a given filter. You can have a bad filter 
without
having an AGC problem.

Ignore the bad filter and AGC problems for a while and work on the other 
items you have on the list of thing you want to do.

You could open the lines to the bad filter and just let it hang.
See if this changes the AGC behavior.
Then every thing but the that IF band width would work for you.
And you can get to the filter replacement whenever you feel the need.
