Re: [Repeater-Builder] Re: Icom OPC-617 Cable
I soldered the f and D bead and sill wont work... I assume you meant you tried soldering D and F, but not both at the same time. Both at once is invalid, and maybe could cause the no tx audio. Maybe there is mic bias voltage on pin 4, and you are loading it down, causing the loss of tx audio. Try putting a capacitor in line. No Rx audio either? Tx and Rx reversed? Does the intercom require a COR input? What model intercom do you have?

Re: [Repeater-Builder] Re: Icom OPC-617 Cable
The solder jumpers D Data and F Flat only affect the freq response of the transmitted audio. A wrong setting wouldn't interfere with PTT. I think there was a drawing in the manual linked below, illustrating the locations. Are you grounding the PTT line and have reprogrammed the radio to allow external PTT? Regarding the speaker, are you getting the audio you need from the connector, but you want to disable the internal speaker? Maybe inserting a 3.5mm plug in the speaker connector on the back will mute the internal speaker. You could put a resistor inside the plug to provide a load.

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?? THANKS FOR YOUR HELP!!!
