So one of the challenges I came up with working in the charity-based radio station is that they wanted to broadcast some stuff from another room back to the studio. Currently they worked around this by having a laptop with skype in the room connected to a call with another computer with skype back in the studio, which worked for them but they wanted a more stable way of doing this.
Just so that we're clear before I start, I am a terrible blogger. I always get the idea of writing a blog and go "yeah that sounds cool!"
