The 250Hz and 400Hz filters are very similar, in reality. Having both is redundant. But having a 1.8kHz or 2.1kHz for SSB RX is a good thing for contesting. Note that some people have used a custom 1.5kHz roofing filter with good success for SSB contesting.
This is all from a little experience, and listening to people with LOTS of experince and knowledge. 73, doug From: "David Ferrington, M0XDF" <[email protected]> Date: Thu, 5 Feb 2009 17:46:52 +0000 I agree with that, but the 1.8kHz sure helps in SSB Contests 73 de M0XDF, K3 #174 -- Mathematics is the language with which God has written the universe. -Galileo Galilei, physicist and astronomer (1564-1642) On 5 Feb 2009, at 16:53, [email protected] wrote: > I have the 400 and don't see the need for 250 > ------Original Message------ > From: Kjeld Holm > Sender: [email protected] > To: [email protected] > Subject: Re: [Elecraft] [K3] Elecraft roofing filters > Sent: Feb 5, 2009 11:27 AM > > Dear all, > > Thanks for all the kind answers. > > Sorry for all that fuss.
