Default DTR650

DTR650 900mhz portables. Has anyone ever been able to identify what the actual frequencies these transmit on?

I believe these frequency-scramble, so there is no way to monitor them and there isn't any real designated frequency for each channel. It hops around from frequency to frequency VERY rapidly when you transmit, and only other DTR radios can comprehend the patterns and receive the message as it is intended to be heard, it isn't like GMRS or FRS where there's the 462.xxx frequency and you can just plug it into a scanner or radio.

the DTR's use spread spectrum, there is no "channel" per se, center freq is 915MHz with 902 and 928 being the lower and upper limits as the other poster advised.
