Wayne et all
My only concern before I order a K4 is how it will work with two high power
AM transmitters near me.
10KW day,1kw night  KVOI south of me and a 50kw day only KUAT AM north of me. 
At some time, I will need to borrow or rent a k4 for a week and see how it behaves
The majority of my operation is between 2-3.5 Mhz, 4 to 7mhz,  7.3-10mhz, 11mhz to14mhz.
I also use my radio on most ham bands.  I currently use a K3 with all bells and 1000MP
The MP seems to handle the intermod better then the k3
The intermod is not caused within the radios but cause by rusty chainlink fence, poor power line 
grounds etc.  My antennas are not the problem.  I tried a sharp cutoff filter for everything below 
3.5mhz.  No positive measurable results.
