[Elecraft] K4 standing on Sherwood's RX list

[Wes]

I agree that TX IMD is an important parameter.  In my experience (measuring a 
sample of two, my K3 and K3S) regrettably, there is no one number to be 
published.  IMD varies with Vcc (or Vdd), output power, load Z and most 
interesting, frequency.  In a K3(S)/100 case, there is another wrinkle, there 
are two PAs, LPA and HPA and those numbers vary as well.

If you want to cherry-pick data, you can get pretty much any answer you want.
