Jed, The receivers are probable AstroTac receivers. Same as the Quantar, just packaged a little different.
The receiver is just what you think. A receiver on the same RX frequency. The unit has a 2 wire and 4 wire output, but only uses the 2 wire for most applications. The unit puts out a tone when in non receive mode, this is called the guard tone. This guard tone goes away when a valid receive signal is received. The received signals audio is then sent out this 2 wire circuit. This circuit takes the received audio from the receiver to the voter and can be many different types, but normally is a phone circuit. The signals come in the voter thru the SQM modules, one for each receiver. This SQM module detects the guard tone and mutes the output to the voter command module. When the guard tone is absent the SQM module measures the signal to noise ratio of the received signal. If more than one signal is being received by the voter the command module picks the best signal and routes it to the output circuit of the voter. The command module is the brains to the unit. The simple explanation. I hope this helps. If you have any more question don't wait to ask. There are many on this list that can help.

It's a damn good machine, a quantar. The one thing i'm not the best at is voting receivers. They only have 2 of them. Here are a few questions, how are they usually connected, i take it there isn't a lot to it, but just trying to learn more about voting receivers.
