A HA!

9888 has bare copper braid.  It will likely get noisy as it ages.  The
advantage RG-214 has is that the shield is that it is silver; it doesn't get
nearly as noisy because silver oxide is still a fairly good conductor.

If you'll pick up the shipping I'll send you as much RG-214 as I can cram
into a USPS flat-rate priority mail shipping box.  Email direct.
