Finding Free Radio Station Frequencies for my iPod
Well, my wife's iPod actully. I've still got it on my To-Do list to get my wife's Honda Civic Hybrid hooked up with proper iPod integration, but until then she'll have to use an FM Transmitter to listen to her tunes. It's always such a hassle to find a decent free frequence to transmit on.
Travis pointed out this incredibly useful Radio-Locator that finds the best radio frequencies in your area for this very reason. There's also amore limited Canadian Radio Frequency Search and International Search.
