Hi Everyone!
Have a question for specialist, i run an sdr with some program to monitor p25 phase 1 signals and i know that LRRP or something other is communicating location data. Because on the control frequency i see that control received the location and i was thinking that i was able to see position data only on uplink frequency wich in my case is supposed to be aroud 800mhz to 820mhz because downlink frequency is aroud 770mhz but i'm receiving nothing and i think it's because the frequency is high and the ouput power is low but i remember when i was a kid there was a exposion of police and firefighter car and i entered in a police car and the police showed to me the computer and he showed a map with all other unit on the territory. So how do they transmit their positon and receiving it? Thank you in advance!
