There aren't any disadvantages of having a radio the only things I think is that there are lots of advantages like...You can listen to music, radio, news and put CD’S into it, anyone can here it, they are not affected by clouds weather, portable, listen to radio in the car.
In my own opinion, there are no disadvantage on having radio.Radio has a lot of uses.Its can be uses in hospital emergencies or you can use it in monitoring your business or even your patient.This kind of electronic equipment is very useful in our daily lives especially to those who have businesses.But this kind of equipment is very expensive if you buy a new one just try for rent radio or lease it.
