[Elecraft] K3 Filter selection

[Dave G4AON]

Jim

I've been using 2.8 KHz and 400 Hz 8 pole filters for about 6 months and 
find they work just fine. I've not found a need for a narrower filter. 
The dynamic range of the K3 is good enough to not worry too much about 
needing a roofing filter for every occasion. I run CW, SSB and data 
modes (including RTTY). I will probably add a second receiver with those 
two filters as well, especially in view of the possible need to match 
filters for diversity reception.

No doubt if you ask 10 owners for their suggested set of filters, you 
would get 10 different answers!

============

I keep seeing talk of the 400(435) or 500 combined with the 250(370). I see
very little talk about the 200. My thought was to use the 400 and the 200.
Maybe the decision should include the 500/200 combination. Is the 200 just
"too narrow" or why don't I see more apparent use of it? I know, what is my
use? I want to be able to operate most all modes except AM and FM where I
have very little interest at this time. Will the 400 cut out RTTY?

The other configuration I was considering was the 500 and the 250 but hadn't
added the filters to my order yet as I was trying to make up my mind but
comments here aren't really helping with my decision.
