Hi Mike. I have a pair of 400Hz and a pair of 250Hz 8 poles in my K3. I'm pretty active, 99% CW, and rarely use the 400Hz (maybe once a day) and very rarely the 250Hz (once a week). The DSP works extremely well. So of these, I'd recommend the 400Hz, and save up for the 250's later if you decide you need even narrower bandwidth than the 400+DSP can achieve. The 8 poles probably have a better shape factor than the 5 poles, judging by my experience comparing the 5 pole stock Kenwood filters with the 8 pole IRC replacements in my old TS850. With the DSP, I'm not sure you'd notice the difference but as you see I went for the better filters and don't regret it. On extremely rare occasions (e.g. fishing out CW callers in SSB QRM from Indonesian pirates) I have wound the filters right down to the minimum 50Hz and even at that ridiculously narrow setting, the K3 is a joy to copy with no appreciable ringing - miles better than the TS850 and indeed any other rig I've tried. I also use diversity with a 30m fullwave loop. Works great! I'm thinking of getting the AM and/or FM filters next so I can open up the bandwidth to listen to a whole chunk of band at once using an AF spectrum program: it sometimes helps to listen to all the callers in a pileup and to choose a clear slot to call. 73, Gary ZL2iFB ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
