D-STAR on SSB (HF)

New ICOM's rig (IC-7100) has DV mode. Therefore, many people try to QSO on HF band. But some one was successful on FM onde only. This is based on the frequency characteristic of GMSK. If you use the GMSK of 4800bps and BT 0.5, Bandwidth of rig is from 20Hz to 2400Hz. Current SSB rig does not satisfy this specification.
