Re: D-Rats IC-705 Raspberry Pi
Your best bet is to use a USB to serial cable which terminates with a 2.5mm stereo plug (RT systems orange cable, or equivalent). Connect the 2.5mm plug to the serial data jack on the rear of the radio. Turn off GPS data and set DV DATA TX to AUTO. Consult the low speed data section of your radio manual for more detail.
In D-RATS, define a serial connection to the USB port where the cable is plugged in (ttyUSBx). The port speed must match the setting in the radio (usually 4800 or 9600).

Anyone have luck with D-Rats on the IC-705 on Raspberry Pi?
I¡¯m using?
And setting Port: /dev/ttyACM0. Which works on the FT8 modes.
IC-705 set to DV Slow data rates, key on audio.
Should autobaud I think.
But get checksum errors.
Thanks for any help.

 here is what is working on a MMDVM Repeater. This Repeater have running a D-Rats Repeater Proxy with the following address: mmdvmrepeater.ddns.net? ? ?

Hi folk. I sent to github the D-Rats modifications to transmitt the weather stations information. in QST window is a new mode, WXGPS-A. This mode read files provided by weather software with APRS information. The file must contain two lines like this.

Other important step is that the altitude in GPS config must be in 0. 73's - David - EA2AFZ

Re: D-Rats with Fldigi as backend modem ?
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 John KL4YFD
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?
John KL4YFD
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.

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 KL4YFD

Hello John,
The WB8TYW repository is just a fork of the
maurizioandreotti repository at this time.? I have not yet posted
a branch for python3/gtk3 as nothing other than the ratflector
appears to work.
Oh.. ok.? I thought it was farther along than that.? Thanks for the
clarification.
So just go to the maurizioandreotti repository for stable code.
So we're still in a world that Python2 and PyGTK are still required.
There is some source in the repo that likely needs be
locally built to communicate with winlink as they use a
compression mode that I have not found pre-built libraries for on
non-Windows platforms.
You mean like this code???
Currently I am fighting with the differences between
the obsolete GTK-2 and the newer GTK-3.?? I have finally got most
of the configure screens working, except for the "radio" port
editing, some of the data is not getting saved.
If you can post that code, I imagine other people can help.? I would
recommend to put it in a different branch in your repo so people
know what it's all about.
The main display still looks like a mess, but I think I what I
learned from getting the config screen working will help with
that.
I have not figured out how to get sound support working on Linux
yet, have not really tried.
Why not just make system calls that call out to shell scripts?? Not
very fast but I don't think this is a speed issue.

Morning Guys, I've only just discovered D-RATS
so please excuse me if this has been asked before......are
there any standalone programs to run D-RATS direct on a Mac
(not using parallels) or is it solely windows (like
Winlink)??

Hi David,?
That was my first thought and, add JS8 and Winlink to it, but apparently you cant do it with Winlink, so, I guess i'll just have to live with being a Mac user as I wont go back to windows, never mind ha ha :-)?
Paul

Buy a Raspberry?Pi and run it there. $35.00
Hi Guys,?
Thanks for the replies. If I was more confident with tinkering on with the IO I would do what Rafael suggests, but i'm not so better not, all my business stuff is on this Mac and dont want to mess that all up. Again, looks like it'll have to go onto the GPD micro computer and just have to swap and change if I want to use D-RATS, which is a real shame.....but I wont go back to windows as a main comp ha ha ha, thanks again for your time :-)?

I don't see why D-RATS would not in Mac OS. Just install all
dependencies with brew and make sure you have proper serial connection
to the radio (in case of using D-Star with an ICOM transceiver).

Re: DV Data over USB Repeated Transmit
Good info Mike. I have my 7100 set up and ready to test.
Tom WW3TRG?
Use the orange cable. Change "connector" menu/USB/DATA 1 FUnction/Data1 Function to "DV Data". Once done, USB2 Function will flip to "off". Leave all else the same. DV Data will use the orange cable instead of USB. All other digital modes (sound card modes like FT8, FLDigi modes, WinLink) all work just like before. The only thing I know of that uses serial DV data is D-Rats.?
I have confirmed reports that D-Rats DV data over USB on the 7100, 9700 and 705 all do this multiple key-ups? when sending digital traffic (from actual users watching the radio). I can positively confirm that using the 2.5mm data jack and the orange cable "solves" this. I say "solves" because it DOES work over USB, just transmits on and off a few times.
