[Kenwood] SSB Filters: Need To Learn More

[Bob Snelgrove]

Hi Gang

I'm still confused about what filters do and how they work.  Sometimes they
seem to make or break whether I can hear and other times seem like nothing
more than a fine "tone control" Any websites that have a nice simple primer
on how filters work?

I'm mostly listening to 40 and 20 meters, SSB.  My TS-850 has the 8.83
switch: (off, 6K, 2.7K.) 455 switch: (12k, 6K, and 2.7K) ( no off)
