[Elecraft] K3 replacing the Li battery

[Gary Smith]

The K3 I have been upgrading & maintaining 
as my back-up radio for the K3s is 9-10 
years old, I bought this one used. I'm 
thinking the battery is maybe old and 
should be replaced with a new one. 

I have a GPSDO attached so frequency 
stability should be maintained with the 
battery loss. The clock I can sync with 
the computer which is time corrected each 
second... I have a backup configuration 
saved via the K3 Utility. 

What is lost from memory that I need to 
re-engage after the battery is replaced?

Thanks,

Gary
