Can't help you on the cable, but I can tell you that the
programming software will not go below 450mhz unless
patched.
I helped a friend do that a number of years ago... the lower
band limit is hard coded. If you do a hex dump on the exe
file you will find a copyright notice for the C compiler that
they used. I forget if it was Borland or Microsoft.
The guy I was helping had the same compiler at work, just
a different version. He compiled a short program that had
the constants "450.0" and "440.0" in all the various forms
(integer, real, double precision, etc...) and brought the binary
home. We did a search for the "450" hex constants. We then
patched the "440" constants into appropriate places and
recalculated the checksums. The patched software worked,
the radio turned out to be a paperweight.
No, I do not have access to the patched software.
