Hi,
For anyone interested into digging into this, here are some recordings
of the mic RF signal during talks at GRCon 15

(Hehe, I bet you didn't expect that when you clicked on that email title :p)
Microphone system is from Shure, their ULXD line of products (
http://www.shure.com/americas/products/wireless-systems/ulxd-systems )
FCC filing for the microphone that was used: https://fcc.io/DD4ULXD1G50
Modulation is 8-PSK and symbol rate is 156250 sym/s
Cheers,
Sylvain
