The BTech GMRS-50x1 radio Programmer
This radio has a section of its memory that is preset to GMRS frequencies that cannot be changed. Some characteristics for each channel can be changed but channels cannot be changed, deleted or reordered.
There is another part of this radio that holds frequencies for receive only. These can be edited, however, while removing the editing abilities from the first page, the second page lost some features. Those have been restored in the update in July 2020. They do not appear active, but the selections (Insert, Cut, move up/Down do work. 07/17/2020
