Siltronix 1011D To Non Amplified Astatic D-104 DuKane 7C40 Wiring

I've got a working un-modified Siltronix 1011D and I'm having a difficulty figuring out the microphone wiring. Evidently someone has put a non-stock cord on this non amplified D-104.

My non amplified DuKane 7C40 Astatic D-104 has a shield, a Black and a White wire. I connected the shield to the common ground terminal on the 1/4" microphone plug . I connected the Black to the tip and the White to the ring. It cuts off the receive audio when I plug it in. It will modulate fine on sideband. I reversed the Black and White wires and it does the same thing. There is continuity between the red and black as well as the shield to either insulated wire (no resistance). Should this microphone cord have 3 insulated wires and a shield? What am I doing wrong?

Any help will be appreciated.

    Maybe. I wasn’t impressed with just clamping the shield wire to the boom with a hose clamp. I built a l bracket with so239 female hubs. I posted a picture on the recent gallery’s.

    Well I cut the matching stubs down 1 inch at a time from about 20” down to 6”. Still no real changes.

    Hello everyone, I have a old courier centurion pll 40 channel SSB, it has the extra channels and it has another switch that just moves the frequency down one channel on the dial, what is the purpose for this?
