Can I ask what type of scanner you are picking this up on? I was told by the county that the new TDMA system could not be picked up by scanners. I have a Pro197 is it possible to receive the signal? Any help would be great. Obviously I'm a newbie.
Hey, welcome to the neighborhood! You can pick it up it on any scanner but it is just a loud buzzing type sound. With experience, the different sounds become familiar.
As far as getting anything audible out of it, it has been reported in various posts here that Mototrbo can be decoded using a pc and a program that so far as I know only runs in Linux. I don't have any personal experience with that. No one makes a scanner to decode it, yet.
I don't think it is a TDMA type modulation either as this would preclude it as a less expensive (than P25 digital) alternative for smaller users. Don't let that confuse you. Get into browsing the wiki pages here and start learning about what you're hearing.
