[Elecraft] Feature density of portable transceivers: K1 vs. KX2

[Don Wilhelm]

The KX2 battery will NOT charge from the external power jack - the 
lithium battery must be removed for charging.  Unless handled with a 
heavy hand, the bottom of the KX2 will withstand many, many removals and 
installs.
If you are concerned about removing the bottom of the KX2, you can 
always use the Lithium battery externally, just plug it into the power 
jack - no internal battery required.

The KX3 internal batteries can be charged from the power jack if you 
have the KXBC3 option installed.
