FDMDV modem worked out well by not only improving
sensitivity over WinDRM, but by allowing one to squeeze the signal
between the adjacent QRM. The modems quick recover time was a real plus
as well - not sure how long it takes for the D-Star modem to re-sync.

Jim,
It would be interesting to see how the D-Star modem performs so please
keep us in the loop. From what I gather, the modem for Dave's codec will
not be as narrow as the one used for FDMDV. It will still use Peter's
FDM modem, but the bandwidth will most likely be closer to 2KHz.
