Downloading and Configuring D-RATS

Get D-RATS for your shack! Digital computer to computer communication with or without the internet!

Join us and communicate with us on a D-Rats data reflector. 

Use the Desktop app with or without the Internet, with or without any D-Star radio, and with or without a KISS TNC.

Works on Windows, MAC OSX, Linux (Raspberry Pi).

Send email, chat, file transfer, and GPS location (static or from live GPS) locally without infrastructure or to a distant station with infrastructure.

D-Rats is the perfect data complement to the Warren County Amateur Radio Association layered voice simplex net.

Very good beta versions are available and are frequently updated. Check https://groups.io/g/d-rats for latest version as well as instructions for installing D-Rats on Raspberry Pi and Linux.

A beta version is at https://github.com/maurizioandreotti/D-Rats/releases/download/0.3.9/D-Rats-0.3.9_WindowsXP.zip

Draft installation instructions can help start you on version 0.3.9:  Click this text to open in new tab. After opening in new tab the installation instructions can be downloaded in several formats using the "File" - "Download" menu feature.

Unzip the D-Rats zip file downloaded from link above into a folder of your choice.

Previously there was a note here for removing 19 files from the 0.3.7 D-Rats build.  The developers have removed them from the distribution, so, checking for the files and removing them is no longer necessary.

D-Rats Configuration (also in Draft Installation Instructions above):

If you are new to D-RATS, you may also set up these items. (Included (plus much more) in Draft installation Instructions )

--  Under Maps select cycle for "Map to use". Change apikey to the one from your free thunderforest.com account

     Get a free thunderforest.com account to get your own apikey. 

--  Click Save to close the Config window.  These settings should get you started. You may need to change these for specific uses.

--   Personalize the My Status message in the lower right corner of the Main window.

      Delete the text and insert your own (e.g. Myname in City, State, [Locator]).

--   (Optional) Also add a folder for 'sounds' under C:\Users\'username'\AppData\Roaming\D-RATS-EV\ for wav file sounds.

--   If you already have a D-Rats Shared file transfer folder on the desktop, it can also be used.

--   To send your GPS positions to others, locally, create a QST that sends GPS-A and set the interval to 20 minutes.

      See info at https://github.com/maurizioandreotti/D-Rats/wiki/191-ERROR-yellow-GPS-messages-appearing-in-the-chat... for formatting

-- Set up the following Chat filters to start with. They may be modified according to your tastes later:

    [QST]  ;  CQCQCQ  ;  Current weather at  ;  Now Online  ;  Now Offline  ;  Now Unattended

    These filters will make having a conversion in the "Main" Chat easier. The large amounts of status information will be diverted to each filter.

Ratflector

The repeater application works like an ethernet switch, for those that understand that analogy.  If not, imagine it like a Y-adapter or a USB hub.  It allows multiple connections to talk to each other.  Sort of a concentrator of D-RATS traffic that can bridge multiple modes.  If you hook to radios to it, it will behave somewhat like a repeater: any data traffic that comes in on one radio will go out on the other radio.  This could be useful for a cross-band digital data repeater.

If you enable network access, then a user from a networked computer could connect to the repeater and see the RF traffic, as well as communicate with other RF users.  This means you can locate your main D-RATS PC away from the radio (connected by a LAN) or allow multiple stations to share a single radio.  It also allows you to let people come in from across the globe to communicate with RF stations in your area.

If you establish a link between your repeater and another repeater over a network or the internet, then you can bridge your local RF users to remote RF users.
