I just purchased a Baofeng GMRS 9R HT for amazon with ABBREE listed as the selling party. This unit also is not transmitting on CH15. When visiting the Amazon site page for the GMRS 9R the are sidebar photos and one indicates on a text note that if the radio does not TX on CH15 it needs to be updated with software. But no mention of where to obtain the software. The sidebar also has a video showing the process for updating the radio using a USB cable for the waterproof radios and using a software file "M8F3_BF_downloaded". It is a Chinese Win 10 computer shown in the video so it is a little less than ideal for the US market. This does suggest there may be a fix. But how to get the software? Any help would be appreciated.
I have contacted ABBREE (www.abbree.cn) for help but so far no joy.
