Will do, I usually operate with headphones and just crank the RF gain down as needed. That + NR + APF + width really rocks signals down to nearly nothing unless they are really weak. Then it's a matter of playing with the settings. I'm finding a need to play with the AGC on some signals where with others it needs to be engaged more. I'm enjoying the process of learning to really use it.

APF on the K3 is useful for pulling out weak signals. I don't see the benefit for general listening. Just as a further clarification. Generally, if your bandwidth is dialed in as 500Hz then your 400Hz filter has been switched out and your current roofing filter is the next wider one. I say generally because it is possible to set wider cutoff points for the roofing filters. 73, Mike K2MK ae4pb wrote > I normally wear a headset but when working I like to listen to code to > help build my proficiency and am hearing a lot of > distortion/buzz/whine.
