Adapting Flex Radiosport headset from Flex-6500 to Flex-6600

I am using a Flex Radiosport headset with my Flex-6500. It came with a cable with a 1/8" TRS plug and an 8-pin Foster connector for the Mic connector. It also came with a 1/8" to 1/4" TRS adapter since the 6500 has a 1/4" jack for the Phones connector.

The Flex-6600 has 1/8" TRS connectors for both the microphone and headphone sockets.

The 1/8" TRS plug on the headset cable can be used as is with the Flex-6600 Phones connector. However an adapter must be built to adapt the 8-pin Foster connector to the 1/8" TRS microphone input socket.

The following adapter will convert the 8-pin Foster connector to the Flex-6600 microphone input socket.


8-pin Foster chassis connector                        1/8" TRS plug
                  pin 5                                                       shank/ground
                  pin 7                                                       ring  mic(-)
                  pin 8                                                       tip    mic(+)

If you use the orange "button" on the headset for PTT, you can add the following:for PTT
                  pin 6                                                       center pin RCA connector
                  pin 5                                                       ground of RCA connector

I would appreciate comments/feedback on this idea.

    I wired this up in a small aluminum box. I hope it works when I get my 6600.

    Sorry, the label "Phones" above should read "Mic"

    Save my day. In a rush to get ready for Field Day. Thought I have the correct adapter/connector. Did not work. Followed your wiring pin out, works great. Thanks for your diligent effort.
