Hi, I have just received my RT91 Ham RF Radio and connected it all up as per your instructions plus the video seen on ebay. When I pressed the PTT Button it will not transmit, the transmit light will not com on. Is this got to do with the connections insertes on the front of the unit and on my handheld not connecting properly or locking in.
Regards
Lui.
