I commented on the value of twisted pair for power and loudspeaker
wiring.

I strongly agree. I converted ALL of my ham gear to Power Pole soon
after buying my first K2. I've subsequently converted all of my other

Guys,
Let's end the APP threads for now. Its one of those topics that will
never end and it periodically pops up all over the net. :-)
As a general statement, we do not require glue and find that when
properly built with heavier wire for the K2/100, XVs and K3 the APP
connectors stay put
Here is an interesting article about PowerPole
connectors in the field. It seems there may be a
practical advantage or two. ;-)

Powerpoles have curved contact pins that snap into
place and hold the connectors
We chose APP connectors for several reasons, and don't regret it in the
slightest:
1. We used them on the K2/100 and all of our transverters, and have not
had a single
failure that I know of. That's many thousands of them. I personally
use them everywhere.
2. It's an emerging standard
I did not say the Power Poles are bad... they are likely superior in some
ways to other connectors, but my point, which so many missed, is the same as
the theory of installed base whereby one item becomes the de facto
standard sometimes regardless of its rating as best or not.
For examples,
I have purchased a lot of HF and VHF/UHF radios over the years that
require 5 to 30 amps of 12 volt power. They all came with factory
connectors. Almost without exception they were connectors that were
not readily available. Most were marginal mechanically and not really
adequate for the peak
