Bull roar! The problem is that he is not operating the radio under
the same conditions as it was when calibrated at the factory and he
has not performed the TX Gain alignment procedure *as documented*
*in the K3 Owner's Manual*.
Charlie is slandering the radio for a design problem that does not
exist simply because he can not read and follow the Owner's Manual.
There is *nothing "factual"* about his report.
