I don't understand ... if you used two different K3's and the same amp (I assume for both K3's), how does that remove the amp as a possible cause of the spurs? I don't think you narrow anything down to the K3 until you check the results into a dummy load. If you have two K3's, transmit into a dummy load with one while you check for spurs with the other.
