13.8 RX
12.2 TX
voltage at distribution box drops to 13.3 on TX key down CW with 2 ft
10awg PSU to dc distribution box with fuses. 3ft 12AWG to K3 still
well within specs and definitly still better IMD that any other rig I
have in the shack I am sure. so no worries here.

Guys
I may need to re-enforce my power lead and connections - but they appear OK.
What I was asking was what does the voltage display indicator show on your
K3 - when compared to mine? I have since understood that the voltage drop
that I see (at the 3 power settings mentioned) is about normal......

Measure the voltage inside the K3, at the powerpole.. you may need
thicker DC lead or clean the fuse contacts.

Folks
I suspect that may have been asked before, so forgive me if it has, but I
need to know what the typical voltage readings are observed (on the K3
voltage indicator) when
a) On receive?
b) With say 10w TX power?
c) With 100W TX power?
Using a DMM, I can see that my 13.8volt linear PSU seems to drop 0.1volt
when going from receive to the 100W TX level - yet the display indicator on
the K3 goes from 13.7v (receive) to 13.3v (10W) to 12.9v (100W) Is this
typical?
