I'm not sure what you're asking. The radio works well on most radio systems that it can receive (analog and APCO P25 digital, in Motorola, EDACS, LTR, and P25 trunking formats). It can't receive NXDN/NEXEDGE/iDAS or MotoTRBO/DMR, which are gaining popularity in USA and Canada. There are parts of the frequency band that are inaccessible in the radio, but in USA and Canada there's nothing useful to listen to in those ranges anyway. Not sure about how well it would perform in other countries.
