I can't get my IC-9700 to transmit when connected to D-Rats. I have tried both comm ports listed for the radio. Works just fine with Winlink using the "A" comm port. I have double checked the menu settings in the radio and all seems OK. All of the charts for radio setup in the videos only list as far as the ID-51. they were all produced before the 9700 was introduced. What am I missing?
