I just recently dusted off my scanners and have the 15X running 24/7 as it was programmed several years ago before I put it up. But I'm trying to get up to speed and get these radios working like I want. I just downloaded ProScan onto my laptop and have been playing around with it until my new model USB-1 cable gets here on Wednesday. Then I'll be figuring all that programming out with the ProScan. But.....question really is, I am very confused. I have looked and read most of the day on the Sentinel software that is compatible with the BCD996T and BCT15X. I just don't know. It seems that there are two out now. One is for Home Patrol radios and the other with the "green" shield is for the HPs. Will the HP version work with my two radios? I can't find anywhere an "older" version for these radios I have. Any help and answers would be appreciated. Thank you in advanced!!
