[Elecraft] What CW Filters do others have

[Robert G Strickland]

I have the 2.9, 1.9, .500 and .200 KHz filters. All are 8-pole with the 
exception of the 200cps filter from Elecraft which is 5-pole. I bought 
the 500KHz 8-pole directly from Inrad since the 400cps filter seemed too 
close to the .200KHz for my taste, and because there has been [in the 
past] some chatter here on the reflector to the same effect. All filters 
in the K3 provide adjacent channel protection, while the DSP filter(s) 
provides the final selectivity. If you're not interested in contesting, 
then the 8-pole narrow filters are probably not that important. My 
general sense is that 8-pole filters, while overkill in many situations, 
are not so much more expensive and give one state of the art filtering 
that stands up over time. While I don't know for sure, I'm under the 
impression that they are also easier to sell if one wants to go in 
another direction. I'd probably go with the .400KHz 8-pole which no 
doubt will serve you well in casual CW.
