I connected the OPC-617 as you said but i didnt solder the D or F bead and is probly why it didnt work. when i recieve audio it comes out the little speaker inside the radio and the PTT wont work to let me transmit. Im not using any data so i guess i need to solder the "D" bead, is this Correct?? is the D bead the jumper on the left side of the radio when the display is pointing at you??
