Doc Searls sez that the iRock should let you select any channel on the FM band. I have one of those. It cost about $20 at Best Buy, and is called the SoundFeeder.
As always, though there’s a trade off between features and ease of use. This thing has a four position switch, to let you select between four ranges of FM frequencies, and a dial to let you tune precisely within that range. Or sort of precisely—it’s not really precision engineered or anything, and sometimes the signal drifts a little.
Driving on a long trip can be an exercise in patience. As you drive in and out of range of different stations, the frequency you chose on the SoundFeeder will inevitably get interference. Then you have to find an empty spot on your tuner and fiddle with the SoundFeeder again until the signal comes in—using the two controls without taking your eyes off the road is pretty tricky.
