Ron,

Just thought of this, and  maybe there is a flaw in my theory that 
someone will correct me on, but perhaps a cheap but clunky way to get 2 
more pf keys is  to use the a/b menu option.

These late model  Kenwood's  let you select a menu A or menu B so that 2 
  ops can have the radio set up with their own  menu preferences, or 
someone may want to set up 2 different sets of menus for different modes 
or styles of operation.

To change menu from a to b or  back again, hit the menu key to go into 
menu mode, then hit the a/b key to change to the other menu set.   You 
could then set menus 79 and 80 for the 2 front panel pf keys to 
different functions.  Of course this  means changing back and forth 
between menu sets, so you would probably  set whatever pf key function 
you would need least often to the "odd" menu set, and leave the 2 most 
often used pf key functions on what would be the "normal" menu set.

Well I've just confused myself, and probably you as well, and maybe I 
missed something important in all this, but  I think it's doable.
