But to be popularised, radio should be easily receivable on the cheapest possible device. That is an FM or a simple radio receiver. So, we have to find new ways of distributing radio waves, possibly through the cable TV operator. You see, depending upon the quality of the cable that is being used, it leaks power. The worse quality of the cable the more power it leaks.
Radio requires much less signal strength.
You can start your own station. You don't have to ask anyone for permission. Cable is a very, very important medium for the Indian environment. There are about 30 million Indian households with cable TV connections. I would say a lack of technological courage.
