I don't think you guys understand that once an agency uses encryption even if digital or analog it is totaly 100% illegal to monitor them. Therefore, there will NEVER be a legal police scanner that you can buy form RS or Uniden that will monitor encrypted transmissions. If you build your own that is your own choice but I would not advertise it and if the FCC found out you could be fine a lot of money and it makes the rest of us in the scanning community look real bad. Bottom line, once a channel or TG is encrypted, then it's time to find another agency to listen to.
