I was thinking the FM filter could be used on other modes as a wide filter. I think the K3 comes standard with the 2.7 filter, plus just the FM filter would allow wider bandwidths in the other modes with decreased performance. I don't contest or DX hunt, and don't generally operate (voice anyway) when the bands are crowded.
My hearing is gone and I don't need anything more than 6kc on AM, but others like it a bit wider. Plus, if you get the FM filter, you could use the FM mode, the AM mode, a wide ssb mode?, and only have to pay for the one FM filter... Am I right in thinking that with dsp, the roofing filter is only real important if there are very close strong signals? Am I right in thinking you could limit the bandwidth on TX to say 3kc on ssb even though you have the FM filter in? That would be 6kc with both sidebands on AM... Best bet sounds like it would be one variable filter that matched the bandwidth selected, from 15 KHz to 200 cycles! Is that not possible?
