Something I have noticed when radio repair has been doing radio checks. For example, if they were doing a radio check on a mobile radio with an ID of 42159, you would hear the dispatcher say Radio 228M (Car # 228,M for Mobile). When they are doing radio checks for radios in 15xxx range, they just come back and say radio 0015xxx.
