Vaughan Radio is not new, actually it is going to celebrate its 40th anniversary!
I would like to recommend some of its programmes as well as the great free app that you can download to actively participate in the shows!!
My favourites programmes are The Show With No Name, with Alberto Alonso, Drive Time, with Kyle Millar, and Test Your English, with Ximena Holliday. Their twitter accounts are very active and they normally answer all your questions and doubts.
Please, check it and I am sure you will love it!
There are very different kinds of programmes, different levels and different subjects, look for the one that suits you best!
