All the engineering activities are managed through 17 transmitting stations,14 broadcasting houses, maintenance unit, planning cell, research unit etc.

1. Maintenance 

Maintenance section is the heart of the Engineering wing. It is divided mainly into two sections, namely, operation and procurement. The operation section collect data regarding present condition of broadcasting equipment, transmitter, measuring equipment, sub-station/electrical equipment, building, budget, civil works etc. and give direction to stations. The procurement section collect indent, requisition from the stations and purchase equipment, spare parts from the national and international market. They also take some steps to repair and replace  existing equipment. This unit maintains the central store and supply spare and raw-materials as per requirement of the stations.
