XM with FM modulation
well with XM do you really need FM??? unplug the antenna after the modulator
"Clumpy Wheel" wrote in message news I want to get an XM radio for my truck and I see that all of the non-specialist stores (Best Buy, Circuit City, etc.) are all pushing these "works with your existing radio" units, which I understand work via FM modulation. But how exactly does that work? I used to have an adapter for my Discman years ago where I had to tune the radio to an unused frequency to listen to it, but it didn't work very well because no matter what frequency I turned to, I'd get some interference. Do these XM systems work the same way? I live in Los Angeles now and I'm not sure it would be possible to find an FM frequency with nothing on it. |
