FTFY...
Don't get me wrong, I DX'ed as a kid, but I don't see the point in fighting with all of the interference from power lines and electronics to listen to much of anything on an AM radio anymore, especially when you can just stream it and send it to the car stereo via Bluetooth. I don't have the patience to deal with all of the noise from AM radio even driving in town.
I find the MLB app worth paying for to stream games, and while it blacks out the TV stream for the Astros you can listen to either home or away feed of the radio nets.
