I know this is the Internet and therefore anything goes, but on this
list, can we at least make an attempt at being polite?

If a conductor (wire) is rated for 20 amps at 120 volts for a given length
(due to it's R),
1 -- The voltage rating of a conductor has to do with its insulation.
It has nothing to do with the potential current flow or what you're
calling the wire's R.
2 -- The applied voltage has no effect on
flow through the same
conductor resistance and affect the voltage drop in it.

There is a point which could be made -- the percentage voltage drop is bigger
at 12V than at 120V.
If the voltage drop on your power supply wire is 2V for a given current, that
is the same
My gosh! Did several people get up on the wrong side of the bed this
morning???
Don't forget that any time you suspect voltage droop at the rig, you can tap
DISP and turn the VFO B knob to read either supply voltage or current during
receive or under full transmit load.

I think that's a big reason why US autos went from 6V to 12V systems
bank in the Late Bronze Age. :-)

I have N6M in my log on 80M at 0329z.
Thanks to all who worked W6ZZZ in Kings County. On 80M and 15M I
was using my K3 at 10-12 watts most of the time. On 40M, 20M or
10M you got Tom with his very old Kenwood at what used to be
100W. He's now trying to figure out how to sneak a K3 past his

I'm looking for troubleshooting ideas.
My K3-10 suddenly died while in use. Here's what happened:

The K3 can safely be set to its maximum QRP/QRO power levels. If any operating
limit is exceeded (temperature, voltage, current drain, SWR, reflected power,
etc.), power will automatically be rolled back.
While this protects the radio 99.9% of the time, things can happen --
lightning, ESD,
Yes, but what about IMD?

Thanks for input. We can all stand down on this one.
The problem turned out to be a power cable after all.
I was using a 3' power cable assembled with fairly light wire (16 gauge). Over
time, the wire had flexed sufficiently at the exit from the APP pin that it
began to fray. Fraying let to
What about it?

K3 resurrected itself after about an hour.
Is this a thermal shutoff issue? What might be the underlying cause?
