That's how my TS-430 is set up.

No Narrow Filter on AM.
Narrow and Wide both operate at 6 Khz.
i.e. No change.

Narrow only works on SSB.

This I think is quite a sensible arangement, unless you have a particular need
to resolve an AM transmission with less Bandwidth.

AM Broadcasts sound pretty Dire on a Narrow Filter anyway.

However an AM Broadcast received on SSB with a Narrow Filter can sound
good, especially in Noisey conditions.

EDIT: Just read the Instruction Manual Page 7, and it does say the SSB Filter should be switched in when
in AM Mode with the Filter in the Narrow position.

So AM should be 6Khz / 2.7 Khz (Wide/Narrow) depending on which Filters are installed
