[Elecraft] Alaska Emergency Frequency 5.1675 MHz USB

[murphy]

I am planning a float trip down a remote Alaska river in the summer and
would like to take my new KX2 along.  Alaska has an official emergency
frequency:  5.1675 MHz USB but the KX2 cannot access it out of the box. 
I get a message something like "Band End".  Does anyone know if it is
possible to activate this band on the KX2?  If so how?
