Hi Knut, Well interference is a very personal thing of course, and I suffer here from power line noise too, especially when it is damp which is pretty much all of the time. Global warming does not seem to have reached the south western tip of the UK yet- we've had the wettest, coldest summer wx for a long time here!
The thing with the NB function is that it seems to take an awful lot of effort in playing with settings to result in any tangible improvement and it has only marginally helped with the power line noise problems despite lots of such playing. 73 Stephen G4SJP On 17/08/2008 22:03, "ab2tc" <[EMAIL PROTECTED]> wrote: > > Hi, > > One of the main reasons for me buying the K3 was the demonstrated ability to > eliminate pulse noise emanating from power lines and ignition noise (I > listened to before/after audio clips demonstrating this on the web).
