Upman, just for your info or programmers info, i noticed that some conventional nxdn users are still using wide 25khz. I brought this to your attention cuz i dont know how this effects the way the 436hp & 536hp decodes nxdn. When scanning some of these or holding on them, seems there is some decoding trouble. Does wide affect the way the fw works or fw affect the way wide is used by nxdn systems?
