[Elecraft] K3 Hardware Updates

[Eric Swartz -WA6HHQ, Elecraft]

This was mis-worded in the doc and is being corrected. It should read:

"IMPORTANT:  You must complete the modification as described below before enabling the vfo noise reduction menu item in version 3.24 or later. Failure to do so may result in erratic behavior of your K3."

Basically, he resistor/diode mod is only necessary if you -enable- the option in the menu (which only appears in V3.24 and later). 

Its perfectly OK to run 3.24 (or later) and not make that h/w mod (as long as it is not enabled in the menu.)

There is no downside to making this h/w mod, even if you do not enable 
the menu option.

73, Eric   WA6HHQ
