FM Radio Transmitter

Model: JDFM1000C

Because Radio-television network development program, after that ACECR branch K. N. T. researchers made the transmitters of VHF band, they began to design and making a 1 kw FM transmitter, in accordance with industries standards(Broadcast) from 1382.Now this device is produced and used after that the laboratory type and pilot of it passed numerous field test and confirm Islamic Republic Iran Broadcasting .We are the only designer and manufacturer of this product within the Iran.
