I have my great grandfathers TRAM XL radio. I bought a cheap after market mic, until a family friend ships me a better mic. After looking at the schematics, I’m still confused as to whether or not the 4 pin mic I bought is compatible with my radio. Any help is appreciated. I should add I’m pretty new to all of this so I’m still learning. I’ll attach some pictures and the schematic for reference.
