Hi... If you look at the InRad Filter website they offer four CW filters for the Kenwood TS830S numbers, 21, 98, 99, and 97. Two are 400hz, and two are 250hz. My question is what is the difference between these, and which two would work best in the Kenwood TS830 for CW?
Any comments or suggestions are appreciated.

Thanks

Rosario:  It would be simple to answer the difference between the 400 and 250Hz filters is 150Hz.  It's actually more than that.

For CW it becomes a matter of choice....some CW ops like a broader filter like the 400Hz because it's easier to tune a signal with this wider bandwidth. 

I would guess (I for one) prefer the 250Hz filter.  What I do is use the SSB filter which is around 3KHz wide for tuning the band and when I want to isolate a CW signal I simply switch in the 250Hz filter.  This cuts out trash on both sides of the CW signal but the tuning is much more critical.

Again, it's a preference.
