[Elecraft] Re: K3 - Which filters to get?

[waltk8cv4612amos at att.net]

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

and

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