I am not able to get my KT-8900R to communicate with the PC ( Chirp ). I just got a new MIRKIT FTDI universal cable, which instantly works with Windows 10. I tried the cable with my BTECH HT, worked first time. All I get with the KT-8900R is ' radio failed to enter the clone mode '. There were no instructions with the radio about PC communication. Does the radio have to be put in some sort of ' clone mode ' first?
