How does a radio prioritize two identical frequencies from two different stations?

2.72K views

Driving into work today, with high dense cloud cover, my preferred radio station was cut in by another radio station of the same frequency. I recognize the cloud cover acted as a dish, and I typically get static through that particular stretch of road, but what makes my radio decide what frequency is dominant of the two? What would be the effect of being in an intersection of multiple stations?

In ELI5 terms, radios work the same as people talking in a room. Whoever is loudest (strongest signal at the receiver’s antenna) will win. If the two people talking are equally loud, then you may hear both, but only pickup bits and pieces of their conversation (co-channel interference) and sometimes you may not hear anything (destructive joins).
