I'm a student strapped for cash at this point, wanting to find the least expensive solution to my current frustration. I have streaming radio playing through half the day on my mac. I desire to listen to it in while I shower, shave, cook, or do other things when I'm not by my G5. I purchased an FM transmitter, but the reception is awful, and does not work well. What are my options to send audio to a radio elsewhere in the house? There is Airport, but do I need to scrap my router (hard wire) and get a wireless router were I to go that route? What is this thing, antena that came on the back of my G5? What can I use it for? Can it be part of the solution? Is it called Blutooth, or something else? If someone gets an airport express, can it plug into a router (hard wired) and then send a wireless signal to a radio in the house? I'm confused a bit on just what my options are. I want to just be able to pick up a signal from my mac with a radio in another room that gets a pretty good signal, fairly clear reception. I'd greatly appreciate some good advice on this, some help for someone who is a bit clueless on all of this hardware stuff. I do have "Hijack Pro" which has something that can be purchased as well called "Airfoil" which broadcasts whatever audio the mac is playing using Airport, but I don't know how to set up airport, or what my minimum requirements would need to be.
