Mixing a stereo signal to mono does cause a lowering of the high end, but it shouldn't cause a mushy sound. Remember that the stunt format was almost certainly being generated locally. There wasn't a lot between the source and the transmitter. For RD the signal started out in its original form (which is often badly engineered to begin with, but that's another story), then gets loaded onto an automation system, then gets sent up to a satellite, then gets downlinked and fed into another automation system, then get sent over the STL and finally gets to the transmitter. Problems can creep in all along that chain. I wouldn't be at all surprised if Disney was being cheap on the satellite bandwidth. That will cause problems. Then there's also the switching between codecs. It's a known problem that feeding the output of one codec to the input of another can get really messy if those two codecs don't happen to play well together. Plus there's the issue of each codec trying to do additional compression beyond what was already done before. At some point things just start falling apart. Add all of it together and if you're not really careful you can end up with a really crappy sound.

I happened to be dialing around this morning.....something that I rarely do....and stumbled upon 910. Still running Radio Disney satellite feed, however it runs for about 12 seconds, then goes dead for about 12 seconds, then comes back for about 12 seconds, then goes dead for about 12 seconds, then.....well you get the idea. I did notice the "mushy" sound too. It could be crisper. What it sounds like to me....and I can't confirm...is that they are running the IBOC again or at least running the 5khz filter that dumbs it down to 5khz so that the IBOC CAN be run although it may not be on. I remember listening on a wide-band radio years ago when they first installed the IBOC and I happened to be listening around sunset and when they IBOC kicked off, the sound widened right up to the 10khz. What I'm hearing now sounds like 5khz to me.

Listening to Radio Disney on 910 compared with listening to it on Sirius XM is like night and day.
FWIW, Sirius XM is running one of their periodic free listening periods right now, at least for the XM radio in my car. I don't know how long it will last. Listening to the vastly larger playlists Sirius XM has makes me long for a subscription. But not enough that I will pay for one.
