Special Rebanding Programming

  • This system formerly used a shuffled bandplan which is different from the standard rebanding bandplan. As of late November 2013, it was reported they have turned off the shuffled band plan and this system can be monitored when programmed as a rebanded 800 mhz system. The legacy shuffled information is listed below in case the shuffled band plan is reinstated.

Base Lower Base Upper Step Offset
851.0125 854.000 25 kHz -319

851.0250 1 868.9875 25 kHz -759
Notes
  • 1: Other shuffled systems might use 851.0125 or 851.0000, instead. The above is correct for Grundy. RRDB indicates shuffled band plan entries by using negative numbers for the offsets.

The above GRE band plan is specific to Grundy. It would not apply to any other "shuffled" system.
