Really? D-Star has no FEC??  I'm shocked!!  (And horrified!)  If it were possible, I would now have an even lower opinion of D-Star than I had in the past.


D-STAR does use FEC in the AMBE sub-frames, but it was not specified for the entire packet or payload.  The D-STAR Data (DD) implementation simply wraps Ethernet frames and does not have FEC.
