Function on medium

Taxi drivers and truckers, among other things, prefer radio stations that have the opportunity to function on medium waves. The advantage of such waves is the presence of an “emergency” channel on which you can find out about accidents, traffic jams, which significantly simplify the choice of the optimal route. Meanwhile, choosing radio stations with average frequencies, it is worthwhile to be prepared for the fact that their operation in urban conditions will be "overshadowed" by electromagnetic obstacles.
