Does anyone know if the federal frequencies in the Phoenix area use a tone (or a NAC)?
I'm using those in the RR Database - Drug Enforcement Administration - The RadioReference Wiki
I've using a Pro-96/106/197.What Scanner are you using ?
I run NO Tones on my Federal Monitoring and use SEARCH
That's my issue - all I hear is static on several frequencies.the only time I use tone is when I am getting routine interference and want to block it out from being Rcvd [usually images]
These - although, I'm not hearing the static today.
418.62500 DEA-PHX-1 Phoenix Ops FM Law Tac
418.82500 DEA-PHX-5 Tactical Ops FM Law Tac
418.95000 DEA-PHX-6 Ops FM Law Tac
418.17500 DEA-PHX-8 Tac/Alt FM Law Tac
No, what I was hearing was more like the squelch was set to its lowest value.Might I add to help you decide if it's actual static or encryption. The analog encryption will sound like what I call the "screech and rush sound". Kind of like a squeal followed by a real loud white noise type sound. Yes, very annoying especially if you happen to have your radio turned up.
Sorry I couldn't be of any more help. Bill can send you in the right direction though. Hell we dont even have a Fed presence in Nashville anyways for me to hear all the different encryption types, muchless clear comms. Good luck.
The noise you heard may be FSK data being transmitted after a station alarm. Chicago DEA repeaters do this periodically, usually about five seconds in length after a series of beeps.
