I was wondering is anyone knows rather or not the new XM wireless transmitters coming out this year can have multiple transmitters? The reason why I ask is I need to cover more space than the 75-100 foot range the transmitter is said to allow. So, if I buy multiple-transmitters with the satellite antenna and position in the various areas of the house I need for coverage, would that be a solution? I didn't know if you could use multiple transmitters or if they would interfer if you used more than just the one. If anyone can check into this it would be great. Thanks.
