I take it from the comments so far that these are pretty good. :) As someone who knows more about PHP than IMD, could you give us the "for dummies" version?
As someone whose main interests will be QRP PSK31 and CW, not serious contesting, which if any of these narrower filters would I benefit from? Also, there doesn't seem to be a lot to choose between the 2.7kHz 5 pole and the 2.8kHz 8 pole filter. I'm assuming that the former is the standard filter - what benefit would actually be observed using the latter? -- Julian, G4ILO K2 s/n: 392 K3 s/n: ???
