I'm wondering if any digital filters exist for the K3. I'm wondering which common filters work best on the K3.
I'm interested in JT65 and JT9 linear phase delay and constant group delay means that the signal of different frequency take the same time to go through the filter so that the waveform is preserved. this is needed to get best results. for narrow filters this is more serious since the group delay changes are at the skirts which are close together. I've haven't been able to find such filter. I've been using the filters on my FT1000D and I do notice the 250 Hz one doesn't seem to help JT65HF as much I would have expected.
