[Elecraft] Re: K3 AGC Adjustment Parameters

[David Ferrington, M0XDF]

To stick my 2p worth in here and not that I'm knowledgeable about this or
want to change them, but ...
Could you put in a config menu item that turns on/off the possibility of
changing them, so default state is off and it uses your settings Wayne.

If the state is changed to on, another 4 menu items (or whatever) become
active and start with the default state until someone changes them. From
that point, when this menu item is on, it uses the setting from the
operator, when off it uses default settings, but remembers the setting
applied by the op and goes back to them if the menu item is turned on again?
