[Repeater-Builder] Re: Icom OPC-617 Cable
Your right i did solder the d and f at the same time. The intercom is a Flightcom 403mc. Ive talked to a few people and it seems the inpedance in my intercom and radio might not match and i need to find out how to change it so they match. this is all new learning for me! --- In Repeater-Builder@yahoogroups.com, Duane Hall wrote: > > > > "I soldered the "f" and "D" bead and sill wont work..."

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?

[Repeater-Builder] Re: Icom OPC-617 Cable
I soldered the "f" and "D" bead and sill wont work,got the PTT to work but i still cant get any audio to transmit or recieve through the OPC-617 cable, i even took the mic out if my david clark head set connected it straight to the pin 4 and 8 and it still wont transmit my voice. --- In Repeater-Builder@yahoogroups.com, Duane Hall wrote: > > You would want Rx audio from 2 and 7, Tx audio in on 4 and 8, solder > bead D in the radio. > > I dont recall if there is a VOX option in the radio.

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.

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?

[Repeater-Builder] Re: Icom OPC-617 Cable
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??
