 Sometime in 1948, Don Henry R. Canoy, together with Robin Cui and Vicente Rivera, set up two home-built tube radio receivers bought from Fideng Palacio of Puntod and placed them in an abandoned chicken poultry house situated at the corner of Velez and del Pilar streets in Cagayan de Oro for the purpose of listening to radio broadcasts from Manila.Canoy and friends ended up listening to radio broadcasts at night when reception was better.Eventually, the friends were all convinced to build a radio transmitter of their own.
