Does the iPod have Internet access when on the road? If so,there's an app called "tune-in radio" that has virtually all radio stations worldwide, and it has podcasts for each show (usually up to 6 weeks worth) saved and ready for you to just hit play.
I can't listen to Dan Patrick live, I listen to the podcast the next day in the car.
In fact, other than 100.3 HD2, BaD and Russ, Tune-in is what I listen to.
The free app has a couple of short commercials every now and then, the pay version (was $1.99 when I got it 12 months ago), cuts all the spots from the programs.
Another cool thing about the app is that if you're listening to a station live, instead of a podcast, you get the local air feed for the market of whatever station you're listening to... Being a Steeler fan in Dallas, I love that I can plug in my headphones and listen to the game for free!
Hope that helps!
