Thanks all guys specially Dave for guiding me, i was busy experimenting with the TA2003 for 38.9Mhz Tv reception and later for FM band radio but no luck, actually the web site i mentioned earlier in post has the circuit where Pin15 of the TA2003 is unconnected whereas in rest of the web sites the Pin15 is connected to Tank circuit(Pin15 is FM RF out), ithink it should work even if it is not connected to tank circuit. i am really confused, can any one help me out the issue is regarding Pin15 only.
