I have been pulling my hair out, trying to program my Astro Saber III. I gave motorola cables and RIB, but when I try and read the radio it says "Communication with radio failed" I also have an XTS5000 that I have used this computer to program and have had no problems. I have read so many posts all over the internet that my eyes are going cross, but still don't have any luck! Any thoughts?? And please use little words, I just a simple fireman, and this is all new to me!! Thanks.
