How many FM radio stations are there in your city? Chances are that you'll know the 'non-stop prattle' entertainment channels. Namma Bengaluru hosts Radio City, Radio One, Radio Mirchi, Radio Indigo, Big FM, Red FM, Fever, of course Vividh Bharati (it doesn't seem to have changed from eons. You can hear the distinct 'coooo' tone when an ad segment begins or ends :-D), AIR FM Rainbow and the lesser known Amritavarshini (AIR classical music). There is one hidden gem, Gyan Vani (or Gyaan Vaani to be phonetically right) which is usually skipped over by the majority or never tuned into. (Disclaimer: depends on how you look at it. It is a gem to me, at least)
Gyan Vani is an educational FM radio station transmitting at 106.4 MHz (the frequencies have changed multiple times in the past few years, but looks like the transmit frequency is being rationalized throughout the country) under the aegis of the IGNOU (Indira Gandhi National Open University) and programmes developed by its Electronic Media Production Centre. Almost all the Indian metros have this station active. The broadcast programs are an eclectic potpourri !!!. Collegiate lessons across different majors, PUC lessons and preps for exams, history, current events, spiritual talks, classical and semi-classical music, scientific talks, health awareness programs, sociology, radio programs from other countries (at times) and vernacular programming.
These days, I am jogging my memory lane on my morning/evening commutes on the war of Indian Independence like Cripps mission, Quit India movement et al and also brushing up on DNA/RNA, nucleotides, Watson-Crick model etc. Some programs are brilliant and some so-so, but the aim is to educate and most of it is definitely worth a hear.
Tune in, if you haven't and have a good time if it interests you. :-D
