Here in SW MO the FBI has a regional repeater 163.8375 In / 167.6875 Out 

A local repeater 163.8375 In / 167.3625 Out 

A south repeater 163.8375 In / 167.2375 Out 

A west repeater 163.8375 In / 167.5125 Out 

There is an NW Arkansas repeater that is 167.6875 In / 163.9875 Out

They are linked with fiber optics and/or regular telephone lines and can be 
linked together or operated one at a time from the console at the office.  
167.2375, 167.3625, 167.5125 and 167.6875 usually key up at the same time.  

Using a voting receiver it only takes one input frequency of 163.8375 to key 
the necessary repeater output transmitters for good communications.  For 
example Voting receiver A hears 163.8375 and knows to key up transmitters 167.3625, 
167.6875.  Voting receiver B hears 163.8375 and knows to key up 167.2375, 
167.3625, and 167.6875.  Voting receiver C hears 163.8375 and knows to key up 
167.2375, 167.3625, 167.5125, and 167.6875 etc.  The voting receivers take the 
best quality signal they hear on 163.8375 per site and keys up the transmitters 
it needs to get the message through.

All of this high price Motorola radio equipment and it is used maybe 2% of 
the year.  165.975 PL 167.9 simplex encrypted when on surveillance's.
