Yaesu FT-757GX Repair annoying FM talk back

My project radio, a Yaesu FT-757GX that I got for cheap on eBay due to its total lack of all functions, is back on the bench. This time it is to fix the annoying feedback I get on FM when transmitting. Hearing myself coming out of the speaker is driving me crazy. One reason I am not on the radio is because I don't like hearing myself, but then I do RUclips videos, go figure. This one is really interesting, really, I wouldn't kid you.

That was some awesome troubleshooting ...

I just wonder if this thing has been this way since it was purchased over 20 years ago.

btw, if you need another tripod and an HD camera, let me know.

Argus Reynolds lord yes! I tried within my budget but I just had to split the difference between family camera and video camera. My Fuji works, not the software connect, that stinks, but it just isn't what I need now that people are actually watching my channel. Thanks.
