Frequency tolerance level - Electronic Circuits Projects Diagrams Free

I think I got my FM radio working 100%

But I have a question. Suppose the frequency of a radio station is 102.9Mhz.
How far away can I go before the station fades away? In other words, what is the tolerance level?

Hmm depends on the bandwith it needs to transmit....i.e if it requires 25khz bandwith to cover its spectrum and the centre frequency is say 88.9MHz (Radio 2 ? lol) then 12.5khz either side its going to be gone......

I Think thats right.....
