Dear Narendra Gor,

It all depends on your local circumstances, so it's difficult for anyone 
who isn't local to say with certainty. in general, you'll need to find a 
frequency without any strong local transmissions, but with a powerful 
distant transmitter. India is such a large country that you'll probably 
be able to locate a suitable station within India itself. But, given 
your location in the north west, you could also use transmitters from 
Pakistan, Afghanistan, or even Oman.

What's the status with respect to digital television in India? If you 
haven't started digital transmission yet, then I'd suggest initially 
trying to observe using frequencies around:

55.25 MHz - using Rx tuned to 55.249 MHz, USB demodulator.
62.25 MHz - using Rx tuned to 62.249 MHz, USB demodulator.

There are (were?) several TV transmissions from India which use these 
frequencies for the video carrier. You are looking for a frequency where 
you DO NOT hear a continuous tone. If you do hear a continuous tone, you 
have a local transmission on that channel and you can't use it.

Do you know Nishant Gor, from the Kutch Amateur Astronomers Club. He(?) 
asked a similar question in 2001 and may have some experience.
