Im pretty sure the KG-935H i recived yesterday is Defective it can only listen i Unlocked it to do testing for a video and I programmed a few Gmrs repeaters in it for testing and it can hear every Frequency i have tested it on but when you try to tranmisit it gives you the screw you tone on amateur frequencies i have tried simplex for ham and gmrs and they wont work either i have gone over and over with btwr software as well as used chirp to read everything and all frequencies and pl tones are correctly set in radio for ham repeaters as well as gmrs repeater the radio refuses to TX on anything will not kick back the repeater nothing i belive there is a PL Tone encode and decode issue were its not transmitting the correct PL tone even though they are Set Correctly which sucks because i have had the radio for less then 17 hours and i cant even use it for anything other then Listening.
