Studio Mic experiment

[Buffalo]

DX being what it is lately (anemic), so I was bored. The plan was a little more complex in the original plan than it turned out. I removed the Behringer equalizer from the mix because window AC unit cycling in the shack prompted me to make gain adjustment quite often. I figured the microphones response should be sufficient. Think it’s doing OK sometimes simple is best!!!

Radio AT6666 pro
Mic EV RE320
Preamp Studio man inline (required 48v phantom power)
XVive phantom power.

Nice, but now radio limits you.
I inject audio directly to series pass regulator.

Thanks Mike , I believe you on the radio limits. As far as a series pass regulator, I’ve never heard of such a thing.

Replace C152 with 4.7uF/16 and apply audio to that capacitor, but break connection between C152 and R276. Lift one capacitor leg is fine.
Works in AM only. For SSB or FM is different injection point.
