@David09 - Yes, you don't need a wide band for every application.
I use a walkie talkie to keep track of my kids when we’re out in a big place like a park and I need to keep tabs on them.
I find that it works very well and while the bandwidth is limited, it does the job. The walkie talkie frequency allows me a limited range; sometimes I hear static, but I understand that on some of the newer digital units this is not a problem.
Nevertheless, I don’t want to shell out the extra money to go digital. What I have works fine for me.
