Naturally , each person must make his / her own decisions .............. but
:
I too operate mostly cw but do ssb contesting too. Not much rtty any more.
I have an Orion 2 with all the there filters and I do mostly S&P cw now at
my age ( 77 yrs. ) !
I never use the 20 or 6 KHz filters but keep the selection on auto. The
Orion is a ham band only rig really. The second receiver is not up to the
quality of the main receiver! It is fine for split or casual SWL listening
and many thing, including the roofing filters do NOT work with the Orion's
second receiver like they do with the upcoming K-3.
So, that being said, I have the 6 KHz ( KFL3A-6K ) on order only because I
ordered the ( KBPF3 ) to turn the main receiver into an all band receiver !
A KFL3A-500 for general cw operation and a KFL3A-200 for contesting. I will
be using the 2.7 KHz for SSB. If at a later date they offer a 1.8 KHz SSB
filter I will get one for SSB contesting too. Maybe one of the variable
filters but then you are mucking around with a knob or something to change
the band width and I am not keen on that. I really would have liked a 300
KHz narrow filter instead of the 200 KHz but is has wide skirts and only 5
poles so may be just fine. Take a look at some of the explanations on
http://radio.tentec.com/amateur/transceivers/tt565
and

Filters are different in DSP radios ................ UNDERSTATEMENT OF THE
YEAR !

Subject: [Elecraft] Re: K3 - Which filters to get?
If I was into DX or contests on CW, I would likely get
a narrow CW filter, but I am not so I did not.
I suspect the K3 will work better than any other radio
with just the 2.7kc filter.
I was just about to post a question regarding filters yesterday. Then this
thread popped up. Which filters I'll be needing (80% CW contesting, 10%
other contesting, 10% DX)? Still: no one answered it exactly up to now.
I currently use 2 TS-850's in SO2R with 270Hz CW filter. I always listen
narrow (don't have the 500Hz filter) and use RIT. Would a 250 Hz / 8 pole
filter do the trick for me? And / or a 5 pole 500Hz?
And what with SSB? Those 10% include major SSB contests. 40m SSB from here
is... mayhem!
PSE advice?
In the FAQ, I read that DSP would 'auto track' the right filter. Does that
mean that you'd never be switching filters by hand? I'd like that. I
almost never have to touch my TS-850 except the VFO dial.
Then there are the variable filters coming out in the future,
PSE define 'variable filters'?
Well, apart from the filters my wish list has almost become an order form
;o)
