[Elecraft] [K3] 12v outlet only puting out 11 volts

[Richard Fjeld]

Unless the circuit has been changed since my radio, I seem to recall two diodes in series in the path to the 12V out jack.  A silicon diode can drop the voltage .7 of a volt (times two).

The P3 should work fine with 11V.  When I tested mine it worked down to 
about 6V or so, although that is not guaranteed.

It is normal for the K3 power connector to show a voltage drop compared 
to the 12V input connector, although 1.5V drop seems kind of high. 
Could some of that drop be in the power cable?
