[Elecraft] K2 KBT2 option question

[Don Wilhelm]

Mark,

The switch disconnects the K2 power input from the battery, so you must 
have the switch in the ON position for the battery to be in circuit for 
testing/operation (also for charging the battery).  If you are using the 
power supply for charging the internal battery, increase the power 
supply to at least 14.1 volts (14.3 volts is better).
