Now since XM merged with Sirius, what channel on xm can i find howard stern on?

If you have sirius channel 100 if you have XM it will probably be at the very least the beginning of the next year and it will probably require you to upgrade your equipment. A good idea would be calling XM and ask when they expect to carry Howard 100 and Howard 101 they probably would be better prepared to answer this than any of us since they have all of the inside info and deal with Mel Karmazon (the head of sirius) on a daily basis.
