I do know that they completely changed to a different kind of radio about a year ago. I have used them but don't know enough about Radios to tell the difference. A few years back there was a webpage that published the radio transmissions from Disney and Universal but from what I understand that is not possible anymore. I don't know why you would want to listen. The transmissions are boring--things like which bathroom needs cleaning or code words for lightning in the area. Nothing is super secret since guests can often hear the radio when a nearby team member is carrying one. The super secret stuff is said over the phone not the radio. If it is something a guest shouldn't hear they just say "Can you 56 me at 4-1234?" Which means call me at this phone number to discuss an issue. The reason that the phone number only has 5 digits is because they are in-house numbers that all start with the same 2 digits.
