Will a Euro-spec radio work in the US?!?
Any radio experts out there?!?
If I install a Euro-spec radio, will it pick up US AM/FM radio stations? I recall that the spacing between the FM stations are different in the US vs Europe, and that one spec will work in the other country but not vice versa...
TIA

EDIT: FM radio broadcasting have differences between USA and Europe. North American FM broadcast channels are on the odd 200KHz frequencies: 99.5MHz, 100.1MHz, etc. In Europe, channels can be on any multiple of 100KHz, even or odd.
This means that some digital tuner from the USA will not tune European stations properly. But a european tuner will work in the US.
FM stations in Europe use a different pre-emphasis than those in North America, 75 and 50 microseconds respectively. Using wrong pre-emphasis has effect on the frequency response in reception. A european tuner in the US will need a slight treble boost, a US tuner in Europe will need a slight treble attenuation.
I have no idea about AM but I think the tuning interval is even more of an issue there.

that's true. Most tuners use standard spacing which is different between the 2 continents. It will still work as a radio, but you will miss a lot of stations. Some designs should still work with both.
What are the FM intervals in the US? In Europe they are 0.1 MHz
I think that the spacing issue applies more to AM than FM.
There is also a difference in the FM pre-emphasis added. I think one continent is 50 microseconds and the other is 75. Forget which is which. That just means that you will get slightly more or less treble depending on which equipment you use where.
