I wondered the same thing this time last year when I was ordering my K3. If I had to do it again, I would choose:
- the FM filter (in case you want to tx/rx AM or FM). I got the AM filter (not planning on doing any FM), but now that the firmware supports AM thru the FM filter... - the 2.8 filter for SSB. I also have the 1.8 filter, but I find I don't use it much for phone, even during contests. I do use the filter when tuning around for RTTY contacts, but I probably would be content with the 2.8 for this usage. - the 400 filter for CW - the 250 filter for RTTY & narrower modes in congested conditions. I went with 8 pole filters mostly because I wasn't getting the second receiver, but I didn't want to have to worry about crystal-matching if/when I add it in the future. Don't forget the BPF if you are in MARS or like listening around away from the amateur bands. -- Michael D.
