It depends on the quality of the receivers. Most receivers in use today will not have sufficient selectivity to be able to receive the desired signal if two 100KW stations are spaced as closely as you describe. 87.5 and 87.7 are right next to each other so many receivers will hear them both at the same time. The frequencies need to be spread apart more. A small town or village should 1) use lower power transmitters - 100 KW is way too much power, and 2) spread the frequencies out more. In a small town, there should be plenty of available frequency space to spread the transmit frequencies out.

Hello all

 

Can anybody on the list assist or point out links to find out more on FM radio (87.5 – 108MHz) band plan and regulations regarding the FM radio stations and it transmitters. 

 

My question is In practical what is the minimum distance (FM zone) between FM stations and the transmitter power output can be used without causing any interference between the 2 stations, say station A operating on 87.5MHz and station B operating on 87.7MHz within the same small town/village.  What is the minimum spacing (KHz) can be used if the 2 stations operate in the same town each operating on 100KW

 

Thank you in advance
