Re: D-Rats on RF has met its demise here.

Respectfully, check the emission designator for D-STAR DV. It is 6K00F7W which is 6 KHz per Icom specs. On every D-STAR transmission the baud rate (voice, data or both is 4800 bps. That doesn’t change running only voice, only data or both.
The transmitted bandwidth stays at 6 KHz. As far as running D-RATS on HF, it’s going to be a pretty unreliable mode anyway. There has been an HF D-STAR voice net running for several years. Keep in mind, that 1200 bits reserved for data is going to be used
for callsign and other signaling when operating just voice. It’s been an unresolved issue whether it’s legal for voice or data and will remain unresolved until the FCC decides to update the data regulations anyway.. For D-RATS, II stick with VHF or UHF for
DV mode or on 1.2 GHz with DD mode.

I would put more faith in ICOM’s published specs that Dan’s opinion. I just wish he’d stuck with D-RATS development. It’s a fantastic piece of software and could have been even more.? Final comment on the subject.

Not according to Dan Smith, the guy who wrote it. I have been looking at anything I can find on Drats for years now. Dan's comments go back a long time... Before he stopped working in Drats.?
