[Elecraft] K3 +DC power supply voltage

[paulb]

Hello folks, 

The K3 here is sometimes powered
from DC AGM battery supply.

Voltage can drop in the evenings on load
to approx 12.0VDC. 

At 100W carrier a DVM reading at the anderson connectors shows
close to 12 vdc; there is a small drop in the heavy
power feed cable.

The K3 LCD voltage displays approx .4 volts lower.

This may be an issue when the AGM batts drop below 12 vdc.

Just wondering if the internal measurment is 
showing some loss in the cabinet wiring or
anderson connectors ?


cheers
