[Elecraft] K2 Firmware Upgrade???

[Brian Wingert]

My 1999, serial number 200-300, Elecraft K2 was last updated with the "A to
B" mod in the winter of 2007-2008.

 

The radio has a dozen mods and fixes and seems to work great.

 

I seem to recall that there are 4 or 5 pieces of firmware that are out of
date.

 

Is there any compelling reason to update my firmware?  

 

Am I missing anything?  Will an update mess anything up?

 

Please advise.
