I have two scanners a PSR 310 handheld and a PSR 400 in my truck. Both are programed the same from RR using the proper ARC software. I only selected the PD TG's on both scanners. The 310 works fine, only grabbing the PD TG's I want. The 400 in the truck gets the PD and all kinds of maintenance talk. I rechecked my ARC software and I only have the PD TG's checked. When it does lock onto one of these TG, it does not show an alpha tag(only numbers). When a PD TG locks on it shows the proper TG alpha tag(Such as Zone1 TAC).I have been locking out the TG's one by one as they come up, but there are a lot. What am I doing wrong?
