Little Rock FD issues
I would check first to make sure you have all the current control channels for the LR system. They are as follows:
854.5625, 854.6375, 855.8375, 856.4375, 859.2625
Note: 859.2625 is the Control Channel today, 1/5.
These may not all be in use (I have read posts on this forum indicating that the system uses only 4 control channels in rotation). My experience has been that at one time or another, since rebanding, all of the above frequencies have been control channels.
Second, make sure you have the new rebanded frequencies loaded in the scanner.
854.5625, 854.6375, and 855.8375
Hope this helps.
