I have a signal link USB and a Kenwood Ts-570-D and Tried to get this working with the laptop (Windows-7) but can't seem to get things going. I admit I know little about this so please excuse what might sound like a dumb question. The Signal Link USB is wired to the 570's 13 pin port and the usb cable from the laptop to the Signal link USB. Am I missing a cable? I tried the several programs on the signal link disc but nothing seems to get the Kenwood 570 to transmit. I have been to 2 dozen or more web sites and nothing is there to tell me what I need or am doing wrong and asking others on the radio leads no where. Does anyone have this set up and know the proper programming or hookup?
