[Elecraft] Unused back panel holes

[Don Wilhelm]

Bill,

That is FB, but just one additional comment - if you are connecting that
supply directly to the battery, you should lower the voltage to about 13.8
volts for a proper float charge - OTOH, if the supply is connected to the
battery through a protective diode, your 14.25 volt supply is correct.  In
other words, the proper voltage depends  upon where you connected the supply
to the K2.
