Unsolderable wire?

'Headend cable' used to be silver plated copper braided coax, but that was abandoned for foil & drain when headends passed 216 MHz. That silver plated coax was over a dollar a foot, in the '70s. -- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge.

Beautiful stuff, strands wound in layers. It takes an unusually high temperature and a long time before the solder wets and soaks into it. It does tin, but I wouldn't say it solders "beautifully", not with ordinary fluxes. Tim -- Seven Transistor Labs Electrical Engineering Consultation Website: http://seventransistorlabs.com

"Kennedy"> Interesting table: > > http://www.efunda.com/materials/solders/solderability.cfm** Shame it is quite wrong. As anyone with REAL experience of soldering knows. What is your experience ? Other than child molesting, that is.
