There's no agreed channelisation for 70cm for digital comms as far as I'm aware, but the RSGB say this
432.491-432.493 MHz Personal Weak Signal MGM Beacons (BW: 500 Hz max)
433.800-434.250 MHz Digital communications & Experiments, including…
434.000 Low Power Non-NoV Personal Hot-Spot usage
437.000 Experimental DATV Centre of Activity (Typically QPSK)
438.800 Low Power Non-NoV Personal Hot-Spot usage
