It could be, but we have to use a certain revision of firmware, due to our radios being on a wide range of trunking systems. When we tried the most recent versions of firmware, we experienced odd behavior on some systems. Some would beep continuously, some would not affiliate correctly, some would cause errors with the data protocols, because our inter-op partners use a different data configuration than we do and the radio can only hold one data profile, i.e., it is radio-wide. L3Harris did come up with a special firmware for us and it works great for all of the systems that we are on.
Most of our frustration comes from the radio just not being durable enough for our first responders. Battery fitment issues, where the battery is so tight that once it is installed, it is almost impossible to remove without damaging the battery or the radio or both. If a radio has a battery attached and it is dropped onto a hard surface, the frame of the radio frame (battery tabs) can bend, locking the battery in place and making removal of the battery next to impossible. Pogo pins snapping off or cold solder joints for these pogo pins, causing boot loops and other intermittent problems. Loose connections inside that radio that we were not allowed to fix, so we had to send them back to L3Harris for repair. Now that our warranty is up and service for the radio is over (for us anyway), our techs have been opening up the radios and repairing the pogos and re-connecting the loose jumper wires/connections. The radios are supposed to be intrinsically safe, but we routinely induct radios that have water or sand behind the screens. We have had a lot of these radios get stuck on the boot screen. Even after removing the battery, the radio still showed the Harris logo boot screen. Sometimes a 3-finger salute would fix it and even then, we would program it, UKEK it and do an OTAR, it would fail again.
We do have a ton of these things, so we do see odd-ball errors/problems that one may never see if they only have one of these radios. We have thousands and thousands of radios on our system, about half being L3Harris and the other being Motorola. We have never had the amount of problems out of the Motorola radios that we've had with our XG-100P's. When our first responders were issued the XG100P's, they turned in their old XTS2500's. We refurbished and aligned them and issued them out to other agencies. Those same 2500's are still going strong. The 2500 doesn't do TDMA, nor is it multi-band, but it is still a way better radio and I'd take one any day over the XG-100P.
