1. Here's the scale for reporting how easy it is to hear someone's radio. If you compare it to tuning in AM radio stations on your car radio, a low strength signal sounds like you have the volume turned down, while a low readabilty signal sounds like you are not quite tuned to the correct frequency.

#	Strength	Readibility
1	bad	unreadable
2	poor	readable now and then
3	fair	readable with difficulty
4	good	readable
5	excellent	perfectly readable
