The article presents the methodology for measuring verification of the phenomenon of fades in the DAB+ SFN. The verification is related to comparing the characteristics of the fades determined theoretically with the occurring fades in the real environment of a large city. The conditions favorable for the occurrence of fading are presented and by selecting the appropriate propagation analysis tool, the places where the occurrence of fading is most likely were selected. In these places an analysis of the characteristics of fades was carried out and the conditions for their verification were determined.
