How far off from its allotted frequency does a device have to be in order to interfere? We are all aware of tuning an old radio where a station (e.g. broadcasting an FM signal) will come in slightly at 102.3 but much clearer at its real value at 102.4 so there is some range for each station.
Does the range change as frequencies increase (i.e. does the margin of error get smaller as you go up the spectrum)?
- sidewndr46 4y agoWhat you're describing isn't anything related to what the original post describes. The "real value" an FM broadcast is not 102.3 but 102.3 +/- 75 kHz. It's expected to be able to observe the signal even with the dial 100 kHz off because the signal width is 150 kHz.
- exitb 4y agoYou should visit a WebSDR site like this one http://websdr.ewi.utwente.nl:8901 http://websdr.ewi.utwente.nl:8901 as it nicely visualizes the bandwidth actually taken by a single broadcast, as well as how tightly neighboring signals can be packed. To answer your question, a broadcast of a certain kind will take the same amount of bandwidth regardless of the frequencies, but it's typical for the higher bands to simply offer more bandwidth and as such offer more broadcasting spots.
