internal battery and powersupply or external battery

roffe
Hi everyone, I am reading my manual and found on side 80 that if you use
a external battery to my k2 you have to disable the int battery on the int
switch but when
you use the internal you can have a powersupply attached and the int battery
enable to recharge the int battery
am I correct  ?

You are correct.
The power supply must be about 14.2 volts because of the diode protection
in the rig.  You loose some voltage across it.
Internal battery will not discharge to the power supply because of the diode.
