[Elecraft] HI RFI and HI CUR messages

[Pete Smith N4ZR]

Suddenly I've begun getting these messages after transmitting, 
especial;ly on 10 MHz.  Only change in my station is that I added a 
borrowed KAT-500 tuner to my K-3 while my KPA-1500 was back at 
Watsonville.   I surmised that the problem might be due to defective 
cables, so I've been changing then out one by one, but no joy.  The 
manual isn't much help - any other suggestions?
