The problem is you'll probably get a wide range of opinions on what is better, some people seem to like a lot of busy frequencies on one radio, and some don't. But like Brad says, depends on how busy it is and what you are listening too. If you can do it, the more radios the better, one radio for one frequency, and if it's too slow/boring the listener can always monitor more than one feed at a time. Look at how the Boston and Kennedy feeds are setup, they are both pretty close to ideal. What area/airport are you takling about and how many radios can you set up ? DJ
