ATF ????

[Tracker44]

Hello, it appears that the ATF frequencies in my area are in the 160.000 MHz and 170/ 000 MHz range and at first I thought were scannable with a Ham Radio . I have never herd any thing on the frequencies that I got here on RR . I have since noticed that they are a P25 system so I guess that rules them out as far as being able to scann them and hear something ????

All encrypted

At least here, suspect same is more so for larger cities just based on activity

Well do you have a p25 capable radio?

As for Scanning and hearing. If you have a P25 Scanner, Yup.
As for ENC, YMMV, can't listen unless you try

Hello and TNX for the information . In this case I had programed them in a duel band mobil ham radio.
(2Meter and 440MHz). I dont believe that will pick them up.
Its just a FM analog rig. I believe its just taking up some space in the rig , but I wanted to be sure before I remove them.
I have never herd any thing on these frequencies , and they are the ones listed here. I thought I would try any way.
TNX again

ATF is nearly all P25, and largely encrypted. You won't hear anything ATF on an analog-only radio. Sorry mate.

 

[Tracker44]

TNX, thats what I thought, but we tried any way, will be removing them from rig.

Not everywhere.

ive been doing some research on SDR and it seems there are quite a few programs that can decode P25 systems. now when i say decode i do not mean un-encrypt. just decode the digital packets to convert to images or voice transmissions. pretty neat stuff and it can be done with a very small investment.

 

[Tracker44]

TNX necromonster., I had entered several frequencies in an anolog radio and a Digital scanner I have .
just removed them from the radio . They had been in there for over a year and I never herd any thing on the frequencies. As far as the Scanner goes the jury is still out on it.
TNX and have a great evening.

Put the list from this site in a P25 scanner and let it run. Eventually you will hear something. If you are out of range of a repeater on Net 1 165.2875 they will show up on one of the simplex channels. Usually it's TAC-1 or TAC-2.

TNX mancow, I will work with that some.to see what may happen.
