I have XM and I really like it. I have two recievers and have never had a problem with either one. I mostly got XM because they have MLB and 700WLW. WLW allows me to stay in touch with news at home no matter I am. When I first got XM they had Nascar also, but I'm not a big enough Nascar fan to switch to Sirius. I have heard from folks that have both that Sirius has better music channels, but I don't know that to be the case for certain. I listen to more talk than anything myself. Which system is better will always be a matter of individual preference.
I think Coast to Coast is on 165 from 1 AM to 5 AM, but I'm not sure. I think Rollye James is on before CTC now, of course, she's about just as bad, IMO. I know she comes on at 10 PM after Mike McConnell and occasionally I'll switch over to 165 to see if they've changed overnight programming, but I find CTC and move on.
Bubba was on WEBN here in Cincy back in the 90's for a short stint before he was fired. I think satellite radio was made for people like he and Stern. Personally, I don't have much use for either one of them, but to each their own.
XM also has Kevin Rutherford on for an hour each weeknight and four hours each on Saturday & Sunday. I really like listening to him and am surprised that more people obviously don't agree with his thinking. If most O/O's out here would listen to him and practice what he preaches, they could pay for a 5 year XM subscription in about a week.
