== Numbers Shortwave Stations ==It is a mystery what these weird stations that broadcast encrypted messages are for. They were many during the days of the cold war. They still exist today and mostly broadcast CW or robotic speech. The CW messages are made up of cryptic words as is the speech. The British Secret Intelligence Service operated one of these Numbers Stations. Further research on the Conet Project can help to shed light on the use of Numbers Stations and their secret messages on shortwave radio.== Pirate Radio on Shortwave ==Pirate radio on shortwave is also known as the HF Underground or DX Pirate Radio. These stations are operating without a license from the country where the station broadcasts from. A pirate shortwave radio station operating in the United States is doing so without a license from the FCC and is therefore operating illegally. Such stations can be a nuisance to the public or cause harmful interference on other frequencies. Some pirate stations are entertaining and cause little to no harm to anyone.It is said that today most of the known pirate radio occurs in USB (Upper Side Band) at frequencies above or below various HAM radio. The most popular range for pirate operators is near the 40-meter (7000 to 7300 kHz) HAM band. Tune in with an Upper sideband tuner at and around 6955 kHz.
