[Elecraft] Battery Low K3

[Don Wilhelm]

Dick and Chuck,

Please read the description for the BAT MIN on page 54 of the Owner's 
Manual again.
It explicitly states that BAT MIN refers to the main 12v power supply to 
the K3 and NOT to the 3 volt lithium battery.

Check the power supply voltage as read in the ALT VFO B DISPLAY. That 
gives you the voltage seen inside the K3 and if you have voltage drops 
at the connectors for the power cable, it will be shown there.
The usual setting for BAT MIN is 11 volts.

You will NOT be "good to go" even if you replace the lithium 3 volt battery.

73,
Don W3FPR
