New to me FT-857D low power output on LSB/USB no problems on CW bad mic?

       I've got a new to me FT-857D it has worked great on 2m/70cm and I just got my general ticket. I'm running a 40-10 EFHW through a ATU100 tuner. 

With the power set to 100 I'm only seeing 30 watts at most on USB/LSB on HF. If I send CW using the microphone I see around 85w output. It seems that I'm getting little to no modulation with voice on sideband.

Is the microphone on it's way out or gone? The only variable I have in play i have my digirig hooked up via the din cables.
