[Elecraft] KX1: no 80 meters with KXB3080

[Bernie Gardner]

I have a KX1 with the KXB3080 installed.  It worked originally, but I've just 
discovered that 80 meters is not available.  There is a B30 option in the 
menu instead of B80.  Turning B30 on enables 30 meters, but not (not 
surprisingly) 80 meters.  I would appreciate a hint on where to look for the 
problem.  It's not obvious (to me at least) how the MCU knows which option is 
installed.

Thanks!
