VOX senders record audio from audio sources other than Uniden scanners
[FAQ-1020] What is a VOX sender?
A "VOX sender" is the Rangecast feed site software operating in a special mode used for bringing audio content into Rangecast from any audio source other than a Uniden radio scanner that supports data communications with a PC. Examples include audio streams obtained from the internet, microphones, radio scanners that lack the ability to communicate with a PC, or non-Uniden radio scanners (the software only knows how to communicate with Uniden scanners). In addition, VOX is sometimes used temporarily for technical analysis of audio from a radio scanner normally used in non-VOX mode.
1 -- PREPARATION
To add a VOX source or channel into Rangecast, you must know this information:
a) What feed site number will be used by the sender providing the content.
This feed site number (two digits, range 01 to 98, leading zero if below 10) must be dedicated to a single VOX source. Do not combine multiple VOX senders under one feed site number, or also operate normal scanners under the same feed site number.
b) What Rangecast channel ID will be used to report transmissions on this channel.
This is a code that begins with the characters CX followed by five digits (e.g. "CX12345"). The code must be unique within Rangecast. To select a number, you can request from Rangecast an allocated block of custom channel IDs for use in your hub.
c) What name you want to have shown on the Rangecast player, for transmissions on this channel.
d) On the PC, which audio input is used for this VOX source.
Usually this is the PCs default or built-in audio input, and the setup process is simplest in that case. However, on occasion an external or additional sound card may be used. In this case, it is necessary to determine which audio input is used.
With this information:
2 -- PROGRAMMER (FOR THE HUB ORIGINATING THE AUDIO)
a) In the Rangecast HTML5 programmer, go to Save Options and choose Hub Overrides in the drop-down menu. This opens a text box where you may enter (or edit) custom channels
b) Enter a line describing the channel, as illustrated below.
CX10330:f=vox,r=59,u=J1,n=FORT WORTH POLICE-FIRE DISPATCH,g=TX0301,s=FW DISP
The format of the line is described here:
"CX10330:" This is the Rangecast channel ID chosen for this channel (followed by a colon, indicating the rest of the line contains information about this channel). The following fields are comma separated, as shown in the image.
"f=vox" This specific text is needed to configure as a VOX sender
"r=59" This is the receive feed site where the channel is recorded.
"u=J1" This is the agency type of the content, according to the standard codes
