Buying Scanners

Emergency services in the Louisville area operate on an 800MHz Motorola P25 digital trunked radio system. In order to monitor this system you must have a scanner or radio capable of 9600 baud P25 trunking. Click here for information on trunking. A presentation on the basics of trunked radios systems was done at Defcon 15 in 2007 and a video of that presentation is available here.

Here's a list of current and past models that are compatible with MetroSafe.

I receive many questions asking "Why is my reception of MetroSafe garbled/dropping out?" The most likely reasons are either simulcast distortion or weak signals. If you're inside Jefferson County, weak reception is unlikely due to the system's excellent coverage so simulcast distortion is the probable culprit. This page explains simulcast distortion in detail. There are a few things than can be done to improve simulcast reception such as loose/open squelch, Attenuation of the signals sometimes helps, Keep your firmware updated in your scanner, Use a directional Yagi antenna and point it at the nearest transmitter site.

If all of the above fail, your only option may be to ditch the scanner and get a used digital radio such as an XTS3000 or Astro Spectra.

WARNING:

Programming a digital trunking radio in a receive only manor is very difficult and requires a lot of technical skill. Improper programming can result in illegal and disruptive transmissions being sent over the system.

Here's a list of digital radios that are compatible with MetroSafe and can monitor a trunked system without affiliating.
