[Kenwood] Kenwood mic cable for mc-90

[Conrad & Kathi Nasatka]

I have a Kenwood TS 950 SDX with a MC-90 mic.
Because I want to hook it up to a Rigblaster Pro I need a longer mic cable ( coiled ) then came with original equipment.  I already called Kenwood Parts as suggested, does not carry anything like that, does anyone have any other ideas where I could get a longer mic cable.
Thanks for reading my request.
Regards
Conrad
