Barry, The K3 has a great tool similar to this. Its called a dual pass band filter but a better description may be a context filter. The firs 20dB or so is narrow but the the skirt widens out below that.

Instead of using a steep skirted 400hz filter, I found that using a broad skirted but nominally narrower (100-150hz) filter in DSP consistently did a better job pulling the weak sigs out of high noise on the Orion. Will the K3 afford adjustability of the DSP filter shape? 73, Barry N1EU _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
