These three categories are used to describe how well a radio signal was received. Signal strength, signal quality as affected by interference, and overall quality of reception, are each given a value from 1 to 5, with higher numbers meaning better reception. So, a perfect signal, very strong, would rate an SIO of 555. A strong signal with a lot of interference might rate SIO of 523, and a barely audible signal wither no interference may get a rating of SIO 151.
