Icom IC-F6011 Repeater Programming

[KD5FMU]

To hopefully answer your question, When Pin 3 on the J6 connector of the Receive Radio detects Carrier Operated Squelch (COS) it sends a signal to the Repeater Controller which in turn sends a signal via the PTT line to PIN 11 on the J6 connector of the Transmit Radio to trigger PTT.

Audio out of the Receive Radio PIN 7 of the J6 connector will go to the Repeater Controller will go to the Receive Audio Input to the Repeater Controller. I know it's a little confusing but here is how I remember it. Audio comes out of the RX radio and into (input) the Repeater controller. Maybe this diagram will help.

So you are indeed using a controller. That was my very first question. Your diagram makes total sense now, thank you.

My only doubt left is the COS output out of IC-F6011. Pin 3 is the Ext I/O 11. You told me to turn on OPTION > Ext OUT (EXO) Horn > RX EXO. So the horn is the COS??

Thanks again for all your help.

Ironically YES. Horn is the COS active low.

Weird Icom logic

Does it have something to do with relaying a real horn? I remember to have seen something on a marine radio.

Yes! Some volunteer firemen would program the radio to honk their truck horns when they received a 2 tone signal to wake them up at night when they received fire calls.

Looking at your nice drawing (thank you for that), could we connect discriminator audio output from the RX radio directly into the IN input of the TX radio? Or must it go through the repeater controller? If so, what is the controller doing with the audio? Thanks.

Well in all reality the controller is just relaying and routing the audio to the transmitter radio. Some more advanced controller's offer audio filtering for audio clarity and they offer a precise timing from the receiver to the transmitter. As well as some controllers offer DTMF control and CW and Voice Repeater Identification. It gives you options if you want them.
Here are a few more diagrams. One is how to directly wire the Transmitter and Receiver for a simple repeater and the squelch tail timing will have to be set in the radio software. The second one is how to directly wire the Transmitter and Receiver together for a Bi-Directional (usually cross-band) repeater.

Amazing thank you!

Fred, will you know by any chance what is the connector type or name that comes with the OPC-1939? See photo below. I am trying to find it at Mouser. Thank you.
