Pulled out Lafayette Telsat 1240 and Silver Eagle mic from my dad's basement. The wires from the mic need re-soldered to the 4 pin connector. Looks like a red, white and blue with shield wires were used a one time. Would anyone know which wires go to what pins on the connector?

Hello Crawdad. Thanks for the welcome and the schematic. The microphone still has this schematic on the underside of the base plate. I was looking for what pins are use on the Telsat 1240. Going to try below that I saw this on another forum which was for Astatic Hi-z mic to Telsat 1240. Kinda makes sense since it looks like only 3 of the pins have old solder on them and the shield wire was wrapped around the blue wire.

Pin #1 - white = audio
Pin #2 - shield = ground & blue
Pin #3 - red = transmit

Those schematics under the baseplate don't always survive the years so I posted one just in case.
White is definitely audio out. They musta been grounding the pin with the red wire to switch the radio to TX.
Best of luck and enjoy your SE.
