Part of this problem isn't the cable part number per se, but how they are constructed by the manufacturer. I have in the past ordered two cables directly from Heil that were the same part number but wired differently. Their QC isn't the best in the world.

She acted as though I had fallen from a star and landed on my head. So I guess people will continue to scratch their heads over *which *Yaesu cable is *the * Yaesu cable. At least if they shop at Universal, as many of us do.
