I chose the stock 2.7k, the 400 Hz and the 200 Hz. I'm a casual CW-only op - mostly ragchews, but occasional DX, QRP and QRQ.
I wanted each filter to have a (more or less) dedicated purpose. The thinking was: - 2.7k for listening in the background, tuning around, before a QSO - 400 Hz when engaged in QSO. Wide enough for a little elbow room or when someone's slightly off freq - 200 Hz when things hit the fan. So far I don't find it too narrow. I chose the 200 over the 250 because I thought the 250 would be too close to the 400. Prior to the K3, for 20 years I used the 250/500/1.8k setup, so I had reservations about switching to 200/400/2.7k. I was very tempted to start with the 250 for that reason. In the end I went for the 200 because when things hit the fan, you need narrow. I was also concerned that the 200 might be too hard on the ears, as even some 250 filters have been in my experience. I don't find this problem at all with the 200. No fatigue. In reality, this trio has worked out perfectly (for my style of operating). I find it highly flexible, yet not so much that I'm wondering which filter to use for a given condition. After using this trio now for a couple years, I doubt I'd ever change it for CW use. Hope this helps. --Andrew, NV1B .. On Fri, Feb 3, 2012 at 10:17 PM, Robert G. Strickland <rc...@verizon.net>wrote: > Well, I'm in for a K3, and I need to pick some CW filters.
