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).

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?
