[Elecraft] K3 - Power cable voltage drop

[Keith Trinity WE6R]

Notes for all;
Check the K3 config menu item "ADC REF".   If at 5.00 it is probably at 
default.
(if at 4.00 a glitch occurred, probably during FW update, and will FUBAR 
the internal metering. Set to 5.00 or read on).
(I check this during checkout, so if it has been in for Service, it 
should be OK).

Higher accuracy of the K3 items like the internal Volt-Meter can be had 
if this is set properly.
With a known external meter on Pin 2 to ground of the 15 pin ACCY connector;
Go into config menu ADC REF and set it.

Also you can stick your probes into the Anderson connectors at the back 
of the radio during full power TX to see the actual voltage to the radio.
(I have a digital LED meter connected  with small wires to the Anderson 
supply wire right at the back of the radio on my K3 test bench).
