That's easy enough. Make your own! I used a computer cable for one end of the cable, (so at least one end was "factory" perfect), shortened it and put a radio shack D-shell on it and ran it between the TRT250 and an off the shelf Ameri-King AK-350 encoder. If you need the schematic, send me your address and I'll throw it in the mail to you (it's 11x17 or I'd just pdf it)...
