I have a 8 pole 2.8 kHz and a 250 Hz filter. What I'm finding is that my "normal-broad" cw width is 200 Hz with the narrower dsp settings as needed. 300 to 400 hz width is only used on cw when I'm scanning a semi-dead band. If the ability to use less bandwidth routinely is a K3 effect, it seems to be a desirable effect.
For agc and gain control, on most bands and conditions, I use the attenuator and only occasionally switch it on on 15 meters and above; my location in a townhouse complex is not quiet enough to allow more sensitivity. I usually have the AF gain at about 1/3 open and adjust the RF gain so that the station that I'm listening to is at the threshold where th "s-meter" increases only on stronger signals which is about the same technique as I used with my Hallicrafters S-40 50+years ago. 73, Dunc, W5DC ______________________________________________________________ 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
