Motorola Taklabout™ T-series model number is quite confusing... Higher is NOT always better.

For example T5725 has less features than T5720, T5710 has more than T5720. T5620 is 1 Watt 22ch FRS/GMRS combo radio, T5625 is 14ch FRS, even doesn't have 38 talk group codes. T5000 has more features than any T51xx~T54xx models.


Some of last digit indicates region, Txxx5 can be found in Canada and Brazil, Txxx2 is UK model for PMR446 Personal Mobile Radio 8 channels on 446MHz, Txxx8 is Chinese model 20 channels on 409MHz. T5725 looks alike T5720 and sounds like "T5720 Canadian version" but functions are identical to T5420.
First 2 digits appears to be identification of case design... NOT! T56xx has 3 different housings.
