Power poles are fine, if they are installed according to directions. Rig
runners are OK for accessories and QRP rigs, but if your K2 has the
amplifier it should be connected directly to the power supply.

Bob,
Is it safe to run my K2 using Anderson Power Pole connections, and/or RigRunner
equipment?
For my info, what is the reason for NOT using them?
I’m rewiring, and I want to do it right!

Nuts, just measure the drop between radio and power supply see if it is
reasonable. Mine is 0.25 volts when transmitting. I run 14.0 out of supply.

As to the RigRunner power pole strip.........PUT IT IN THE TRASH where it
belongs. NEVER NEVER NEVER use a power distribution strip to power a 100
watt radio. ALWAYS connect the radio direct to the power supply terminals.
NO exceptions!

After more checking, I suspect the internal 100W amp is the common factor
in the poor keying characteristics I'm seeing and hearing about from my
rig. I am trying to determine if my power supply is doing it's job.
I'm using a TenTec 963 switching supply rated at 25A continuous. At rest
the K3S panel display shows 13.6V, with full power key down it dips to 11.5
or so. This seems like a lot. I'm running the power cable thru a
RigRunner Powerpole strip. If I can dig out another power supply from the
packed boxes I can wire the K3S directly to the supply.
Is 11.5V at key down enough to cause the slow rise time being reported?
