Hi. My transceiver was released in December 2018. He has a problem, if i set the AM or FM modulation and press the PTT button, then the output power increases very slowly, in about 1 second. In SSB modulation, there is no such problem; power increases instantly. I checked 4 transceivers 891 and everyone has this problem. Check yourself, is there a problem? Here is a video showing the same problem.
