Hospital "Ham." -- In his room at the Wahroonga Sanitorium, surgical patient Phil Edwards, amateur radios crank, holds strange little parties. Guests who live as far away as 400 miles from Sydney include a blind ex- digger of World War 1, a polio victim, a completely paralysed boy and a dairy farmer from the Clarence River district. Phil twiddles the dial of his radio transmitter and is able to tune-in and hold conversations with his "ham" friends. June 16, 1950.
