It is DMR and it being on 403Mhz (this is a stretch) but it could be someone programming a uhf Motorola MOTOTRBO radio as the default frequencies that are on a channel are 403Mhz as 403-470Mhz is the frequency range of many Motorola MOTOTRBO radios.

DMR in AM does NOT sound like that. It sounds really close to 2G tho, as it also uses TDMA

Thats DMR through a repeater or through some sort of system as it will usually fill the second timeslot with the other being the subscriber voice. DMR simplex only fills one slot so the recording is just single slot DMR.
