Jim:

First thing that comes to mind is a ground loop.
I've seen the ground connection open on cables when the computer and the
programmed device are powered from different outlets. Further
investigation showed the grounds of the two devices were substantially
apart, thus causing current to flow in the connecting cable, making it
fail....

Perhaps you are seeing a similar problem?

Thanks

Over the last 5 months we have programmed many TK372, TK2100, TK2200,

WIN98 with KPG56D, KPG48D in a DOS box or within Windows for KPG88D
and KPG75D (native Windows RSS) on a 600 MHz Dell Optiplex machine.

But 1 eBay Hong Kong cord and 4 Kenwood KPG-22 cables have quit working
suddenly and mysteriously...3 in the last 7 days.

This same computer and com port does Ritron product and Motorola just
fine with other appropriate cables.

Any opinions why we're "killing" Kenwood cables?
