With a tip of the hat to Dan (KK7DS) and Pete's (AE5PL) applications that use the extra data space in the D-STAR DV signal, I don't believe it was ever intended to be a reliable and transparent data service. It's great to have a place to send some data along with voice data (and its FEC), but I would venture it was intended more as an SMS/GPS/Signaling service rather than a data communications transport. One of the primary goals of fitting the total signal in 6.25 kHz (4800 bps) limits the amount of data one could push through the system anyway -- it is data streaming for realtime data (voice).
DD is the real data service in D-STAR and I think it is a shame that it was not spec'ed and implemented at multiple data rates/bandwidths, including a 4800 bps (6.25 kHz) data transport. mungewell wrote: > > > D-STAR Low Speed Data has so much promise, but Icom's serial port > implementation severely handicaps implementation. > -- John D.
