TRX-1 or DMR issue?

[TDHG4U61]

I programmed my TRX-1 to receive American Airlines at DIA where I work. I tried DMR conventional, trunked system,NFM but the signal sounds distorted, like listening to a single sideband conversation. There is a strong signal but can not make out what they are saying. I programmed the frequencies from the RR database. Any suggestions? Maybe they are using connect-plus or Turbo Net.

Are they using Privacy Plus or similar?

I you go to the database, you'll see that the TG's are 'TE'. So, yes, they are encrypted.
