Ray McMartin headed an interesting company. His company had a history of "re-starts" and production of a lot of low cost equipment, including SCA generators and receivers. Starting in the late 1960's McMartin began selling consoles and transmitters, many of them designed by Charlie Goodrich, some with help from Juan Gregorio (x-Sparta).

Parts and service currently are available from Charlie Goodrich, former factory production manager at 
Goodrich Enterprises, Omaha, NE. (402-493-1886)
