I assume you mean for the yoke with the built in PTT?
I wouldn't recommend this, you understand, but a telephone handset cable works very nicely (I've been told they were also made by Belden)! <img src="/ubbthreads/images/graemlins/crazy.gif" alt="" /> <img src="/ubbthreads/images/graemlins/tongue.gif" alt="" />
(Use the black one though! OEM didn't come in colors! get the one with the round cross section, not flat!) <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
I use all kinds of Belden cables in my home studio. They actually are one of the more quality cable companies.
