Uniden DMA Radio Memory Limitations

Even though Uniden's DMA radios use Dynamic Memory Architecture, the amount of memory available in the radios for the various DMA elements is limited and varies by radio.  The table below was constructed from the information found in the radio owner's manuals.

As an example, if you were programming say a BC246T by hand using the menu system and tried to add a new system # 201 you would get an error saying there is not enough memory to accommodate it.  Even though the total memory used in the radio may only be at 50%.  The same holds true if you are using ScanControl on your PC to program the radio.  When ScanControl tries to create system # 201, or Group # 21, the radio sends back an error message saying there is not enough memory to complete the action.  ScanControl, in turn, puts up an error message to the user saying there is insufficient memory and suggests trying to delete systems, channels or groups to "make room" for the additional data.  This can be confusing because the user can see that less than 100% of the total radio memory is used but ScanControl says there is "insufficient memory".

Use the table below as a reference when building and editing your DMA radio systems in ScanControl in order to avoid "hitting the wall" imposed by these memory limits.
