That's only if your AGC gives you grief - hold PRE/ATT and AGC, and if your 
S-Meter goes off the scale and your rig goes deaf, you want to change Ctrl-C8.

I don't understand enough about the AGC circuitry to know whether to 
recommend it to anyone who's NOT seeing those symptoms. It may be that one 
particular batch of X1 crystals was a bit dodgy and needs an extra pull in 
the right direction, and there may be some disadvantage in doing this if 
your X1 is "normal"...

... after all, there's well over 5000 K2s out there that DIDN'T need 
Ctrl-C8 changed, and only a handful of us who DID.
