Do a search on bit rate and myfi. Yes, bits vary by channel, some might have 25kbps or less! About 6 years ago, i think the max rate was 38kbps, then they started to really crush it.
People have done the math using a Myfi. The Myfi has a small amount of memory, the trick is to clear it, record a station until it is full. do the math to determine the bit rate..
Back then, even though it was a higher rate than now, people called to complain (including me) and the XM people all seem to have the same script :
"What? You don't like the sound? We haven't gotten any complaints. Have you tried adjusting the bass and treble?"
Like playing with the tone con controls will bring back the sound! Back then, they were still claiming "Digital quality sound". WTF is digital quality sound?
But, getting back to the question, the last time I saw numbers for bit rates, the range was somewhere between 26 -28, but much less for some talk channels and I am sure by now, those traffic report channels probably sound like someone is underwater.
If you were to record something at 28kbps on your pc, it would sound like sat radio. Try the internet streaming version of xm and you'll find it sounds much better. It does because it uses a 128kbps rate, at least 4x better than sat. Of course, dynamically, the sound is still crushed.
