D-Rats with Fldigi as backend modem ?

 

Hi everyone,

I have connected D-Rats to Fldigi as a backend modem before and it just magically worked, using?TCP port 7322 on 127.0.0.1 (start Fldigi first)

Is there any interest in adding Fldigi as a menu-option in the D-Rats connection settings?
Personally I would love to have this feature, but i'm really bad at GUI programming.

Thanks,
John

I have tried this also. I was reading the Flarq documentation and was struck by how much sounded like D-RATS. So I opened D-RATS preferences and made a network connection to fldigi on port 7322. The two programs connected, but the results were disappointing. First, DO NOT USE OLIVIA! It just won't work. Then, since D-RATS chat text is sent in one continuous string with a checksum at the end, any corruption of the data (like a fade on HF) will result in no text being received. Third, mail and file transfers are very slow, and are longer than the ACK waiting time in D-RATS, so the transfer fails. It seemed like a great idea, but we couldn't make it work. But we still have D-STAR radios and TNCs to fall back on.
 


What mode did you use for trying the transfers?
If you use a slow mode it will timeout yes. Have you tried a faster mode?

Try using Fldigi 8-PSK-500 or faster. The speeds will be as-fast or faster than D-Star data, and should fix the timeout issues.

I need coffee, lol
