Advantages of shortwave broadcasting

Even in the modern world, there are still many largely populated places, where the information could not reach the audience, because there is no Internet or FM coverage, or because of the local censorship, because there are disasters destroying the local infrastructure and for many other reasons.  

Delivering information via satellite or Internet in such areas is very difficult or impossible, due to the lack of infrastructure and electrical power, the inability of people to pay or install fixed satellite dish installations or the requirement for payment of traffic subscription fees, which the listeners usually can not afford. The local broadband connections are very vulnerable, satellite receiving equipment too. In many of cases the listeners already own radio sets with ability to receive shortwaves. Such HF equipment is also mandatory and already installed on ships, air planes and vehicles and offices of organizations using HF for utility communications, and could be easily tuned to shortwave broadcasting frequencies to gather audio content. Several million radio amateurs have HF receiving equipment with as well. 

No special infrastructure is needed from the broadcaster to set up shortwave transmission, usually delivering audio files or streaming to the transmitter site via internet is enough.      

Using small, simple, battery powered  and cheap shortwave radio set, the audience could receive fresh and unbiased information from abroad using Shortwaves, being sometimes the only efficient and very simple option for media content distribution via radio specially in troublesome regions
