I had the following problem with FRS radios. When you test them at a random time, there are very few other people on them. When you go to some event where they would be very useful, there are so many people on the air that you can hardly say anything. Example: you go to an air show or fair with your radios. Everybody else that has them brings them also. If you're communicating between the roof (antenna adjustment) & your living room, They work great. At the time that they would be most useful, they're useless.
