I'm having the same issue with my AR 152. I'm so frustrated as there does not seem to be a way to undo this. Using chirp inverted my power settings and also dropped the highest output down from almost 8 watts to about 6 watts. Has there been any progress on a solution to resolve this? And I understand this is a GMRS forum but I haven't seen this discussed in any other place. I would like to get to the bottom of this issue if anyone has any helpful solutions.
