Terminology
What is Scanning?
Unlike standard AM or FM radio stations, most
Scanning stops on an active frequency and remains on that channel as long as the transmission continues. When the transmission ends, the scanning cycle resumes until another transmission is received.
What is Searching?
The UBC 245XLT can search each of its 10 bands to find active frequencies. This is different from scanning because you are searching for frequencies that have not been programmed into your scanner. You can choose between two speeds while searching. Turbo Search, a new feature for Uniden scanners, can search the VHF FM bands at up to 300 channels per second.
What is Trunk Tracking?
Conventional scanning is a simple concept. You enter a radio frequency in your scanner’s memory which is used by someone you want to monitor. So when your scanner stops on a frequency, you usually know who it is, and more importantly, you can stop on a channel and listen to an entire conversation. This type of scanning is easy and fun.
As the demand for public communications has increased, many public radio users don’t have enough frequencies to meet their needs, and this has created a serious problem. Trunking radio systems solve this problem.
