Phil,
The only reason to use matched filters is diversity mode reception. For
split operation, you want to have enough filtering to work your way
through the pileup to select your TX frequency. For many ops, that
means using a wider filter to find that proper TX slot, while others
prefer a

I would get 1.8Khz SSB filters instead of the 2.1KHz.
