Gary, The K3 is an excellent CW rig as that is what I do about 90 percent of the time...and now mostly on the low end of 40 meters. I just have the 5 pole 500 Hz filter right now and find no objection at all to the roofing filter. These filters are not exactly what most people think when you think about a filter. The roofing filter limits the amount of signal enter the radio...like a roof. With the DSP type of radio like the k3, the filters are really in the software and I can run all the way down to 200 Hz without to much difficulty. I usually run about 400 Hz and find that satisfactory for most DX QSOs. I do have a filter between the ears as reported also by my wife.
I've wanted to get a 400 Hz 8 pole filter but have not yet had a need for it. The key to remember is these filters are roofing filters and the "bandwidth" of each mode is set in software as it is a Software Defined Radio. Lee - K0WA In our day and age it seems that Common Sense is in short supply. If you don't have any Common Sense - get some Common Sense and use it. If you can't find any Common Sense, ask for help from somebody who has some Common Sense. Is Common Sense divine? --- On Tue, 11/25/08, Gary Smith <[EMAIL PROTECTED]> wrote: From: Gary Smith <[EMAIL PROTECTED]> Subject: [Elecraft] K3 CW filtering To: [email protected] Date: Tuesday, November 25, 2008, 3:05 PM Hi, Am readying myself to invest in a K3. I am a CW op, rarely on any other mode, (haven't used any other mode in over four years). I chase DX and enjoy the occasional contest but am not a dedicated contester. On the other hand, I tend to go 100% into any of my endeavours and when I contest, I contest to the best of my abilities. I currently have an Omni V with a set of Inrad CW filters and find them a tad too ringy for my liking though I find the 2.4kHz with the 250Hz narrow filter in line pretty effective. I find the 250Hz filter with the 250Hz narrow filter also selected almost too noisy for my pleasure. Sans ringing, I would love a 50Hz filter but reality says I need something wider. That probably says enough about my CW desires as regards the K3. With that, what filter should I go with to maximise my CW experience?
