Default what size wire to use for 30amp 12v circuit ?

So, now your saying your theory only applies to certain radios? Then you
shouldn't make blanket statements like you did. You mislead the average joe
who reads this newsgroup. It is not common knowledge and while it may be a
"fact" for "one" radio, it is certainly not a "fact" in general. I disproved
your statement on the Icom 735, and today I disproved it on the SEA222,
Icom-710, Icom-802, SEA235 and a Yaesu FT-897. I'm not disputing the fact
that minimizing voltage drops on an HF installation is of prime importance.
I just think you are way out of line making such a statement and claiming it
as a commonly understood fact.

Eric, just how did you disprove this? Using the same setup that you
used in your original experiment? Well, now, why don't you try modifing
your setup and put 30Ft of #14 Wire from your very stiff powersupply to
the radios.
Now try the putput power test again, and come back and tell us all
what you find.

You see Bill Forgey, the Retired Chief Engineer at SEA, and I, did all
of these experiments years ago in the SEA Engineering LAB, and concluded
that yes, this was the case. One of the reasons that more headroom in
the HF Amplifier sections was a prime design factor in the SEA 322-330
Series Radios, but which still did not completely resolve the problem of
trying to operate a 20+ amp Current draw, thru a less than steller
Power Wire.
