On Febuary 14, 2012 one of the PPSTN dispatch radios went from encrypted to open P25. For 10 days I was able to hear all the dispatches made from that radio. That radio did 95% of the dispatching. No one knew about it. Why ?The encryption note was also interesting to learn that they use the same talk groups for ENC and Clear. I guess that explains why on some groups you hear both in use at the same time. Does anyone know if ENC units get a beep everytime they transmit to warn that they are in the clear?
