In the summer of 1986, engineer Bob duTreil completed an engineering study for the broadcast license application, for which the fledgling station agreed to pay $2,500, the first of a number of debts incurred by the organization. An application dated July 4, 1986, was submitted to the FCC. That was rejected August 5, 1987; an additional $1,500 of engineering work was required to comply with FAA requirements, and the proposed tower height was lowered to 98 feet. There were also special requirements because of a non-interference treaty between the US and Mexico, although the tower site was more than 200 miles from the Mexican border.
