Radar was portrayed by Gary Burghoff in both the film and on television - one of only three actors from the film to reprise their roles on television. The other two were G. Wood and Sal Viscuso.
On M*A*S*H, Radar's uncle died and his mother needed his help since she was otherwise alone tending to the family farm. He was able to leave the army on compassionate grounds. In real life, Gary Burghoff made the choice to leave because he wished to spend more time with his family.
When Gary Burghoff left "MAS*H" after its seventh season, he transitioned to other projects, including directing and acting in theater. He also appeared in a few television shows and films, though none reached the same level of fame as his role as Radar O'Reilly. Burghoff later focused on his passion for painting and wildlife conservation. His departure was largely due to a desire for more privacy and a less demanding schedule.
Besides Radar (Gary Burghoff) and Klinger (Jamie Farr), the voices on the PA are Sal Viscuso or Todd Susman. Sal Viscuso was on camera in several episodes as different characters (Dear Sigmund, Post Op, and Tea and Empathy), and Todd Susman was in Operation Noselift.
