D-Star vs FM under impulsive noise conditions
This video shows the performance of FM vs D-Star under impulsive noise conditions. It is clearly audible that D-Star works without problems when FM is hard to understand.
The transceiver is a modified former C5 C-Net phone with DVmodem by DO1FJN. The test signal was provided by DL3OCK. It contained the same voice information in D-Star and FM modulation on two different channels

D-Star vs FM in weak signal condition
This video shows the comparison between D-Star and FM at around -115dBm.
It is clearly audible that D-Star has some advantages against FM if the decoder can stay in sync. The microphone of the camera does not represent the FM very well. In reality the FM sound was slightly better.
