Hi again, I have reread this entire thread and I think I start to see what's going on. The KX3 only has a DSP noise blanker to my knowledge and some people who have both KX3 and K3 say the KX3 's NB is much better then the K3's for power line noise. I am guessing their K3 is set up for IF blanker only or with very little DSP assist. On the K3 the DSP NB works very well and I see the gentleman in the UK with the very convincing audio recording is using a little IF blanker assist. That audio recording is very much in agreement with what I am hearing when my power line noise is bad (usually on hot, humid summer days).
