I actually used the 6700 in place of the K3 on 160 this morning. There was one thing that stood out immediately while trying to get the best S/N on a weak 3D2 station. I was a bit clunky trying to adjust the RF gain and AGC-t values to find the best. would it be best to locate them under the same tab somewhere? The popup rf gain values are hidden under the LoopA and LoopB buttons somewhat and the rf gain bar has poor response to mouse clicking the preamp value you want. It increments each spot to the right (sometimes) but not when clicking to the left side to get from say 20db to 0 db. with all this clicking it takes forever to zero in on a weak station. Just my thoughts and observations so far... It wasn't that I couldn't finally copy the weak station it just took so long getting there.....and maybe getting used to where the controls are will speed things up.... eventually through repetition and band conditions Ill know exactly where to set them and Persistence will keep them there for me........ now back to the K3.
