Trying to listen for 70cm beacons on the AOR DV10 proved impossible due to the frequency error and drift, trying to listen to the GB3UHF beacon on 432.430 MHz we heard nothing until we tuned the radio up 1.2kHz, with this level of frequency error it makes the AR-DV10 totally useless for CW/SSB on any of the amateur bands.
This video shows the comparison of the AOR DV1 vs the DV10
