Harper together with Ceylonese and English radio enthusiasts founded the Ceylon Wireless Club. They experimented with radio broadcasts in 1923 the first experiments took place from a tiny room in the Central Telegraph Office - gramophone music was broadcast with the aid of a small transmitter captured from a German submarine.
