    JA> Repeaters for CB! WOW!   
      
   Yes, we've had them since the end of the 1970s! :)  In the cities they have   
   tended to be cesspits for every carrier dropper and pissing contents, but away   
   from the major cities, repeaters are community hangouts and resources, commonly   
   called upon during emergencies.   
      
   Repeater specs are:   
      
   Output frequency 476.425 - 476.6125 MHz in 12.5 kHz steps (UHF channels 1-8 and   
   41-48).   
   Input frequency - 477.175 - 477.3625 MHz (UHF channels 31-38 and 71-78, 750 kHz   
   offset).   
      
   The reason for the odd channel numbering is the band plan.  Channels 1 - 40 are   
   from 476.425 MHz to 477.400 MHz in 25 kHz steps.  Channels 41-80 were added   
   when the channel spacing was changed to 12.5 kHz in 2011.  They start at 12.5   
   kHz above channel 1 at 476.4375 and go up in 25 kHz increments (i.e. between   
   the original 40 channels) up to 477.4125 kHz.  So the repeater segment is   
   actually contiguous, despite the spacing in the numbering.   
      
   ... (Oh no, (I'm nesting (parentheses) again...) help!)
