[Elecraft] Splicing mic cables

[Jim Wiley]

I have a question that perhaps someone on this list might have the 
answer to.  


Does anyone know of good method for splicing tinsel-wire cables?   I am 
trying to repair a microphone extension cable that  got ripped in two. 


The cable in question is a 6-wire microphone cable, with conductors that 
look to be about 24 to 26 gauge in size.  The conductors consist of 
copper foil wrapped around some sort of fabric core.  Attempts at 
stripping were dismal, using several  different techniques.   The cable 
is normally terminated into a RJ type connector, that apparently uses ID 
(insulation displacement) to connect to the wires.   I am considering 
something like Scotch UR type splices, but don't want to spend money on 
a box without knowing if they will work or not. 


A new cable is a possibility, but the existing one is built in to a 
console, and several hours of work would be involved in removing  and 
replacing the existing cable. 


Soldering to individual conductors does not work.  The resulting 
connection is weak and very fragile.
