In his letter to I&B Minister Manish Tewari, Jaiswal has requested for installation of a 10 kilowatt (kW) transmitter for the station to enable better quality of service, a statement issued by the minister said.
Jaiswal, who is also Member of Parliament from Kanpur, pointed out that the 1kW transmitter which the station relies upon at present is proving to be inadequate, with listeners complaining of poor audio quality.
A statement issued by the Jaiswal says that the three private FM stations in the city were using 10kW transmitters to reach out over the airwaves while Rainbow FM, with its 1kW transmitter, was barely audible on radio.
