I think the original question has morphed. It is really two questions. The
operational range of the K3 as one. The second is really the optimum range of
the K3. In dealing with the drops between the K3 and power supply how much is
excessive? My Astron is set for 14 volt and drops at the K3 under XMIT. How
much drop would be necessary for the IMD to rise to an unacceptable level? Or
put another way what is a reasonable goal for the drop in the power cable or
power distribution to the K3?
Zero millivolts would be ideal but not obtainable. I'll admit to not having the
knowledge or test gear to measure the IMD. If instead of getting 100 watts I
could only get 95 watts to me that would be insignificant. But I don't want to
XMIT a "dirty" signal either.

I believe that the transceiver will operate below 11 volts but it is better
to keep it in the higher part of the voltage range. My power supplies are
all 13.8v and I use heavier cables than Elecraft supplied which keeps it
around 13.5v while transmitting.

What is the minimum recommended voltage for the K3S? Using the stock
Elecraft 5' cable, I drop from 13.3 to 12.7 volts on key down.
