The term Radio sport is of contemporary Eastern-European beginning and is used to refer to one of a number of competitive radio activities for amateurs. The term is frequently written as a single word, like in radiosport, but could be seen as two split words, like in radio sport. Friendship Radiosport Games (FRG) is the name of a multi-sport event incorporating competitions in several radio sports.

The Friendship Radiosport Games is a worldwide multi-sport competition that includes events in the range of sports collectively referred to as radio sport. The Friendship Radiosport Games were held for the first time in 1989 in consequence of agreement between Portland, Oregon, USA and Khabarovsk, Russia. Since that time, participation in the FRG has been extended to other Pacific Rim cities. The Friendship Radiosport Games are traditionally held in the last month of summer.

The debut Friendship Radiosport Games took place in Khabarovsk, Russia, in 1989. The initiative for a friendly radiosport games between two cities belongs to Yevgeny Stavitsky, an amateur radio operator in Russia. Amateurs from Portland took a trip to Siberia to take part in the games, a competition that would have been impossible just a few years earlier, because the two nations were engaged in the Cold War. The second Friendship Radiosport Games took place in Portland in 1991, sanctioned by the Friendship Radio Society, and contestants from Khabarovsk had a flight to Oregon to participate in the event. This would found a tradition of organizing the competition in August of each odd-numbered year.

Extending the games to other sister cities, the host for the next Friendship Radiosport Games in 1993 was Victoria, British Columbia, Canada. Besides competitors from the United States, Canada, and Russia, participants from the city of Niigata, Japan also attended to the games in 1993. The next Friendship Radiosport Games took place in Khabarovsk, Russia and competitors from all four sister cities were represented at the event.

Two years later, in 1997, Tokyo, Japan happened to be the fourth city to host the Friendship Radiosport Games. In the 1999, the games returned to Portland where the ARDF competition was also assigned the IARU Region Championships, the earliest such IARU sanctioned event in the Americas. In 2001, the games returned to Canada, where competitors from Melbourne, Australia participated for the first time. Undermining the traditional model, the Friendship Radiosport Games didn't occurred in 2003, but in its place were held in 2004, for the third time in Khabarovsk, Russia. The invitations to participate were further sent to amateur radio clubs in cities of Buchon, Korea and Harbin, China.

The Friendship Radiosport Games have historically featured events from all activities collectively referred to as radiosport. This includes Amateur Radio Direction Finding, High Speed Telegraphy and HF contesting. Some participants take part in just one or two of these activities, at the same time as others compete in multiple events.
