[Elecraft] K3 Voltage on TX

[Fred Jensen]

That's way more drop than I experience with a 4S1P LiFePO4.  Things to 
check:

Length and gauge of wire [remember to double the length when calculating 
resistance, it's a round trip for the electrons].

Poor regulation in the power supply or depleted battery or battery at 
the end of useful life.

Voltage drop at connectors

Voltage drop at fuses.
