<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]--> Folks,

  

 I'm using the Ray Allen electric trim and their stick grips in my  GlaStar.  I'm using shielded two-conductor cable from the PTT switch to the  intercom.  I need to splice that cable and originally used Bob's soldered  lap splicing technique but kept the exposed wires very short to be able to  replace the shield.  Long story short -- one of the wires shorted to the  shield so I had a "stuck mic".  

  

 My specific question is:  what's the best way to replace the shield  after splicing shielded wire?  To do it right this time, I'll have to  expose about 2" - 3" of each wire.

  

 Best regards,

  

 Bob

  There is no electronic value in having this wire be

  shielded. Therefore, no value in attempting to maintain

  shield integrity in a splice. Prepare the end as shown

  here:

  and splice onto the ends. Cover joints with heat shrink.

  You can use a twisted pair of 22AWG wires to extend the

  shielded conductor.
