Already answered (i.e. sometimes it could eliminate the desired signal!) >There are many times when it is highly desirable to notch strong CW signals or carriers whilst trying to listen to a weaker DX signal underneath, but usually at a different pitch. The problem is that the K3's Manual Notch is relatively wide. An interfering signal must be >100 Hz away before Notch doesn't attenuate the desired signal (this per some plots N1EU sent me). For this reason, you're much better off using narrow DSP Width (<200 Hz) which is also easier to set up quickly versus the Manual Notch. Another option is to use PBT to shift the DSP filter to eliminate the interfering signal. BTW Orion even has a much narrower Notch than the K3 but I seldom used it instead of simply narrowing DSP Width. 73, Bill W4ZV -- View this message in context: http://www.nabble.com/Auto-Notch-on-CW--tp15631565p15634450.html Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
