Now I dont have to listen to the awful TBS announcers anymore!

Works perfectly.

Im using Soundflower as an intermediary to delay the Gameday Audio from the MLB site -- no FM radio necessary.

Install Soundflower and restart. Then in the Sound panel in your System Preferences, set the Output to Soundflower (2ch). Then open BatCrack Radio Delay, pick Soundflower (2ch) as Input, Built-in Output as Output, turn up the volume and set the delay.

The volume control is a bit fiddly to use -- otherwise its perfect!
