Phil, For me, that is an awfully wide filter for CW. I normally tune CW with a filter set to 700 Hz. a 2.4kHz wide filter hears a lot more of the band - too much for me.
OTOH, there are some operators who like to use a wide filter to hear a lot of what is going on around their frequency. If you are in that class and have a good "filter between the ears", then by all means use it that way. I might point out one other disadvantage of using the wide filter for CW. If a strong signal is on the band say 1500 Hz away from the weaker signal you are trying to copy, your mind may be able to easily separate the two, but that strong signal is also activating the AGC and all signals in the passband will be reduced in strength because of it. That is why narrow "roofing filters" are offered for the K3 - even though the DSP can create a narrow filter, the hardware AGC is still responding to the strongest signal in the passband. The same argument applies to the K2. 73, Don W3FPR On 2/8/2011 10:39 AM, Phil Hystad wrote: > A possible follow-up question --- one recommendation I received (indirectly > out of band from this group) was that the SSB option was useful for the wider > filter even if you do not plan to do SSB.
