Ivan, you wrote: I am about to purchase a K3 (k). My main interest is certainly CW with occasional forays into SSB and even data, and I note the selection of roofing filters available, no doubt the 8-pole are somewhat better but what is the general feeling regarding the bandwidth(s) to be included.
>From the operating you plan, and having operated many different K-3s, for SSB & CW I would suggest: 1. The standard 2.7 KHz filter for occasional SSB. As others have mentioned, the roofing filter is to protect the DSP. 2. A 400 Hz, 8-pole (or 500 Hz-8 pole) filter for general CW operation (I find anything narrower too restricting for general operating "band awareness") 3. If you are inclined to contest or dig really deep for rare DX, add a 200 Hz or 250 Hz filter, also. (Crank it in--only when needed.) I'll defer to others about the better bandwidths for data modes. 73 de K3YD ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
