SIMULTANEOUS AUDIO IS PLAYED IN SEQUENCE - NO TALKOVER
With a scanner, whenever there are simultaneous transmissions on two channels you want to monitor, you will surely miss something. The scanner can only receieve one signal at a time, and when a broadcast signal is gone, it's gone forever.
Rangecast solves this problem, by recording every transmission.
If you are monitoring multiple channels, and two transmissions on channels of interest to you are simultaneously recorded, the Rangecast player will play one while buffering the other. The second transmission isn't be lost, and will be played in its entirety as soon as the first transmission has been played for you.
For this reason, Rangecast provides the user with more complete reception of multiple broadcast channels than would be possible with any scanner.
