I have a question about that video also, so instead of creating a new topic I'll just hijack yours. :p
This question may be really retarded but I'm very new to RF. In that video rbcp made it pretty clear that the CB had to have a digital screen, I'm wondering why that is. Is that due to the fact that you need to broadcast in digital? Or is it still broadcasting in analog?
The reason I want to know is that I'm looking into GNU radio as a cost effective way to get started with RF. But from what I understand of it so far, you need special hardware to broadcast and receive in digital using GNUR.
I live just down the street from a BK so I could mess with them from the comfort of my home.
