This is one of my main questions now. I finally ordered mine with no
optional filters and plan on adding them to the order before ship BUT I do
not know which will be the best

If you're interested in CW or data modes (RTTY, PSK, etc), then you'll
perhaps want to invest in one or more narrower filters, perhaps one or two
of 200, 250, 400, 500 Hz. If it's only one narrower filter, I'd suggest
either the 400 or 500 Hz filter. I think of

The most comprehensive writeup I've seen is here:

I think Dick has put together an excellent summary regarding the available
filters. I
I can vouch that there is no reason to order both the 400 and 250 filters.
When I first ordered my K3 on the phone, whomever I spoke with (and I can't
remember) convinced me that these two would be the best combination for CW
operation.
In reality, there is very little difference between the
Repeating what I've posted here previously, the first thing to get firmly in
mind about the K3 crystal filters is what their purpose is. They are not
used to determine the bandwidth you are using on any mode. (Yes, you need
the 2.7 or 2.8 for transmit on CW, RTTY and SSB. The AM and FM filters
Thanks to all for the comments. (I am using a 2x 400Hz and 2x 250 Hz
Inrad combo in my MP for selectivity at this time, and a wiide
roofing filter)
The subject is very interesting to me since I expect my K3 sometime in
June.
How about this one for the K3:
2.7 standard
2.1 8-pole SSB
John,
I ordered the 500 hz and 250hz filters The 500
will be great for the casual stuff. When it
gets tough like the 160 mtr contest with signals
30 and 40 db over S9 all over that 250 will be
king. I have 2 TS-850S with inrad 400 hz - they
are ok but I assume that when my K3 arrives I
won't here
