D-RATS RF Access Point [2 Attachments]

 

Hi Patrick,

This isn't directly related but you might want to think about putting a VNC server (i use TightVNC) ?on that box so that when it's at the site - or even still at home you can have remote GUI ?access to the computer. ?(Unless you're already running an ssh server.) ? ?:-)?

Is port 7322 used by Wires-X?

Best regards,

Stan ? N3KDA

This is an update to a project that I have been working on.

My goal is to offer RF access to a Ratflector so field units can communicate with internet based assets. I currently have a D-STAR radio and a KISS mode TNC connected to the Ratflector. The network connection is only to another computer on a local network at this time. I have successfully tested the RF connections with club members and all is working well.


I recently discovered that D-RATS and FLDIGI running on the same computer can exchange information via TCP port 7322. This also works on a Ratflector. I am running FLDIGI on the same computer as the Ratflector and have them connected via TCP. FLDIGI is now transmitting all data coming into any of the other inputs of the Ratflector.


My question is this: What frequency and mode should the FLDIGI connection be using? My original concept was to use PSK250 on a frequency near 3580 kHz USB, into a NVIS antenna. My reasoning is that there are already FLDIGI users operating in this frequency range and they would not need additional hardware to get connected to D-RATS. It is also possible to read the chat messages with any program that decodes PSK.


Other frequencies and modes are also possible. I would welcome any suggestions regarding the implementation of the FLDIGI connection.

A drawing is attached.

Right now I'm using Teamviewer for remote access, as it's a Windows XP box now. I'm thinking I want to change it to a lightweight version of Linux. I'm looking at LUBUNTU. The .iso still fits on a CD. I also have to look at how to put D-RATS in the startup queue. I'm beginning to think the fldigi module is not going to work as well as I had thought, so I might drop it from the project.

I do not know what port Wires-X uses.
Fldigi uses port 7322 to communicate with its ARQ module. That is how I got it talking to D-RATS.
