Results of initial D-RATS testing on DSTAR
In my previous post I mentioned having loaded D-RATS. Since then I have been doing some experimenting with the help of Rick, VE3CVG and Manfred, VA3WK. We have found messages can be passed with good copy via simplex. We have also found that D-RATS and d*Chat can be used together. A text file was sent via D-RATS, first as a text file and then as a file using the DDT format (they are two different routes in the software). The transfer went well. I would be interested to try sending compressed image files next.
A good range of radios were used, specifically the IC-91AD, IC-2820 and IC-2200H. When setting up, make sure you have the right baud rate set in D-RATS (for your computer serial port) and your radio. If not you, will likely see a string of question marks on the main message window when data is received.
So, if you have your D-STAR radio linked to your computer, give D-RATS a try. By the way, the development team is working fast as there was eight days between the 0.1.4 and 0.1.5 releases, so keep checking for updates.
Rick has pointed out to me that there is a Mac application that offers similar messaging capabilities. This software is called dTerm and the company producing it is currently looking for alpha testers. So, whether you use a Mac, Linux or Windows there is now software to allow you to do keyboard to keyboard communication using DSTAR.
If you are in the Ottawa area listen on 145.670 MHz (simplex) for messaging signals.
Should you have any interesting findings using any of these applications, or hints and tips, I encourage you to post them here.
