Hi, I've been searching for some operating tips on how to strategically employ the following K3 controls:
- NOTCH - NR - NB - WIDTH - SHIFT As good as the manual is, I still feel like I don't understand how these really work and when I should use them to get the best possible results. To date, I've been randomly turning them on and off, adjusting their various settings to see what they do. But I'm hoping some of the experts here can explain how and when they like to use each of these controls. I have been using my K3 for about 4 months. Lately, 40m has been a little more noisy for me (about 4 bars of noise). I suspect its QRN, but there may be some QRM as well. Activating the noise blanker (NB) will usually drop the noise by 1 S unit. Recently, I've been fiddling with the NR settings to improve the signal quality (this was very helpful on last night's 3905 40m SSB net - the noise without NR on was just horrible). I don't understand what the different NR settings are doing, as you move from 1-1 thru 3-7. Going from 1-1 to 1-4, it sounds like the person on the other end is moving farther down a long hallway - the signal gets more faint, disappearing into a surrounding quietness. 2-1 and 3-1 sound very similar to 1-1. And, I don't understand what NAR1,NAR2,NAR3 through WIDE1, WIDE2, WIDE3 settings on the NR feature are doing for me. I don't notice much difference no matter what I select with those. What about NOTCH? I don't seem to notice any difference whether it is engaged or not. Finally, I can sometimes use the WIDTH control to reduce interference from nearby signals, but if someone is booming in 2 kHz away, I can't seem to shut them out. Anything else I can do here? I am not sure what SHIFT is used for, perhaps this can be utilized? I have the 2.7kHz, 1.8 kHz and 400 Hz filters installed. Thanks for helping a newbie! 73 de Jeff, W6UX ______________________________________________________________ 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
