Here are a few audio clips of Range Security transmissions, recorded in the Rachel area. We used a scanner similar to the Uniden Bearcat 3000, linked to a laptop with voice activated recording software.
Note: To reduce download time all clips are compressed with GSM 6.10. Not all players support this new standard. If you are unable to play the clips download them to disk first and then play them with Windows Sound Recorder. If you are using a Mac, you can download a free player and converter here.
Click on the speaker to listen to the clips. Enjoy...
