"Jim Taylor" asked:
I have a programming cable for Yaesu VX-2. What do I need to do to use
this with VX-7?

Hello Jim,
look he http://home.comcast.net/~sllewd/vx7rmain.htm and
go to the section PC CABLE. It is neccessary to reduce the
diameter of the VX 1 2 5 R cable. Otherweise it could not
contact correctly in the hole of the vx7r contact.
Maybe it would be also possible to make an adapter and
use the CT-91 cable from YAESU.
merry xmas and a happy new year.
