Don... Seems like all of us who contemplate buying a K3 go through the filter agonies. I ended up with the 2.8/8-pole, 1.9/8-pole, 500/8-pole from Inrad, and 200/5-pole. I am almost totally a cw type, using ssb only for dx that isn't on cw. While not operating ssb much, I wanted a filter arrangement for that mode that would be "ever lasting." For cw, the 250 and 400 from Elecraft seemed too close together to really be different. I remember the 500cps mechanical filters from Collins, so that's always been my standard for cw. Then, for tight work, the 200 seemed nice. As Don says elsewhere, the dsp sets the ultimate bandwidth, while the filters "protect the door." That said, I wanted filters that would provide the same long-term satisfaction as with the ssb filters. I've operated more ssb than ever in the past because the K3 does such a good job on receiving ssb. As it stands, the K3 here is set for the future with no looking back.
