radiod config file

For creating our radiod config file we start with a template called radiod@rx888-generic.conf, which can be found in /etc/radio in a regular KA9Q install on a Ubuntu machine (more later).

We copy the template to our config file named: radiod@rx888-wsprdaemon.conf    (in the same directory). After filling out all the necessary  parameters, we get this file:

Radiod Rx 888 Wsprdaemon Txt
Plain text – 8,0 KB 100 downloads

 

The file has the extension txt. Change that to conf. So the file name is radiod@rx888-wsprdaemon.conf   (all small characters).

In the file you find a lot of comments how to select parameters.

There is also a very good document of Clinton Turner, KA7OEI, here.

The file is changed sometimes during several experiments, so see it as a working document, to create our websdr and wspr site.

The config file has three sections. Global, rx888 and channel definitions.

It looks very complex, but if you read the different sub sections, it comes to live. Most of all the details are explained in the document of Clint, KA7OEI, here. And more specifically here.

 

So, that's all for radiod to do,.......

Installing radiod on a Ubuntu machine is discussed later.
