[Elecraft] K3 voltage indicator

[G4FNL]

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.

What are you using for a Power Supply?

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?
