Am I able to program a xts radio without windows xp?
Depending on which model XTS that you are referring to? If the XTS radio is the XTS3000 that is the same CPS that is used for the Astro Saber and is known as the Astro Saber & XTS3000 CPS which requires a Window XP or Vista 32-Bit Operating System. I never tried loading this on a Windows 7 32-Bit Operating System. I'm not sure that this CPS will work on a 64-Bit Operating System.
As for the XTS1500, 2500, and 5000 series radios, you will need the Astro 25 Portable CPS for the portables and the Astro 25 Mobile CPS for the XTL1500, 2500, and 5000 mobiles.
I never tried to load the Astro 25 programs on a Windows XP or Vista. When I first started using the Astro 25 CPS, it was on a Windows 7 Operating System and I think it was a 32-Bit Operating System. When I get a chance, I'll get the laptop out later today and check and if it is a 64-bit system, I'll update my posting.
Currently, I am using the Astro 25 Portable and Mobile CPS programs on both a Windows 10 and 11 computers.
