Rangecast provides an innovative way to monitor two-way radio communications.
Conventional methods of bringing scanners onto the internet have been hampered with common limitations. With audio streaming technology, the user is constrained to the particular selection of channels that are included in the audio stream - there is no ability to add or remove particular channels, to dynamically focus on an area or event of interest. In essence, you're listening to a scanner that someone else has programmed, and hoping that the predefined mix works for you.
Rangecast sweeps away all those limitations. With Rangecast, you have total control to select the particular channels that you want to hear - and nothing else. You can change these selections at any time, by turning channels on/off on the player interface. If several people in your office are using Rangecast, each of you can independently choose the content that's right for you.
The player on this introductory page is relatively simple, with 7 channels from Boston police and fire departments. This is sufficient for becoming familiar with the basic controls on the Rangecast player. Other layouts can simultaneously select and monitor over 200 individual channels at a time.
On the Rangecast player, buttons usually correspond to individual broadcast channels (such as the dispatch channel for a particular fire department). You can turn these channels on/off by pressing on the button (on-green, off-red).
To turn all channels on/off at once, use the "All +/-" button. It's sometimes convenient to turn everything off, and then activate only the particular channels of interest to you.
If you hear something of special interest, and want to lock the player to that one channel, click anywhere in the text area showing the source of the current transmission.
The player will enter a "hold mode" (orange text, gray channel selection buttons) and will only play transmissions on that one channel. You can release the lock by pressing a second time in the same display area.
If you want to hear a transmission a second time, press the "Replay" button, and it will be played a second time. This is particularly useful if you need to copy an address, or take other notes based on the content of the transmission.
