Adding Positivity 70s radio station

[dround]

I would like to add a number of the Positivity radio stations (https://positivity.radio/)  to the list of radio streams in Moode. 

I've can't seem to find the exact URLs for the streams. Looking at the source code for Positivity 70s it seems that the URL looks like this 

http:\/\/stream.radiojar.com\/6wxz7fm8nuquv

When I add this as a radio station nothing happens. 

I'm not a programmer but is there a simple way to find the precise link for one of these stations so that it can be added to Moode.

Thanks for any help.
