    Sorry, but I don't think it's XM at least not the satellite.  I pointed
right at XM-2 and when listening to 60.75 (I still have a 123 MHz IF for 2401),
I got a very strong signal just like you received.  Only problem is that it does
not change much when moving the antenna all over the place.  I did however find
that it went away when I powered off the downconverter.  If it is XM, I'm more
inclined to believe it's the gound repeaters.  I'm going to have to dig out the
XM frequencies (I have them around here somewhere).
