I was having trouble with my P3 going into brownout mode when transmitting 50
Watt digital. This used to be fine, but seems to have been getting worse over
the past several months. When I monitored the power on the front panel of the
K3 I found it was dropping about 1.5 V when transmitting digit

Good Evening,
Conditions were not as good as last week on either band. But they
were good enough to gather a few check ins each. QSB was moderate today

Shockingly bad grammar, from a supposedly educated person:
" I use an old Zero case for my K3, only because I found it orphaned."
You probably guessed that the case was orphaned, not the K3.
Good thing my English teachers have been dead for decades.

I find running at reduced power may not indeed save anything. It is
just a "feel good issue" issue augmented by "old ham lore".
My K3S running 100 watts on 10M is 43% efficient. That is 14.0 volts
at 16.5 amps for 231 watts total DC input. While running 50 watts it
is only 31% efficient.
Corky,
If you can adjust the power supply output, set it to 14.3 volts and see
if the problems go away.
Measure at the K3, not at the power supply.
Eliminate your power distribution system and connect the K3/P3 direct to
the power supply.
Let us know if that helps.

The P3 should operate normally down to 8V or les. I have successfully
powered it from a 9V battery.

The actual wording is “This is the sort of nonsense up with which I will not

It’s often attributed to Winston Churchill but there’s some debate about that.

I will also be posting this to the Win4K3Suite reflector, but I wanted to
touch all bases.
The other night, while doing some FT8 operating, I changed bands to 80m.
I've operated on 80 plenty of times with this setup. The antenna connected
is a Comet CHA-250b vertical, and is resonant on all bands

On many many occasions I have found DC Power Strips to be the fault of
many issues. Poor voltage regulation due to added resistance in the
path is the primary one. Yes, every connection and contact adds
resistance. For this reason, I've always practiced and written, one
