If you care about SQ at all, using an FM transmitter is not the way to go. You're stuck with a 200KHz signal deviation so the bandwidth *****, most cheap FM transmitters have an 18KHz rolloff anyway and the signal level probably isn't too great with a Part-15 accepted transmitter anyway.
What's your definition of "others nearby"? //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif You could always spend a couple of hundred bucks and import an overpowered transmitter that sounds a lot better (not as good as a hard-wired connection, mind you) but remember, something like that would be illegal to use on the FM band and may lead to fines if they ever catch you with it //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
