Radio receivers did not lose sovy relevance presently. This type of equipment was considerably improved in comparison with the very first models, became more functional, compact and convenient in use. Modern radio receivers are capable to catch a signal in AM and FM ranges. FM range (ultra-short waves) is the most popular type - in it the bigger number of commercial channels conduct broadcasting. The transmitted signal in this case is more better. Generally, for radio listeners there are quite enough these ranges. If you want to have an unlimited range of ranges - you should pay attention to all-wave radio receivers.
