Just received a brand FT-991 and the transmitted AM audio is horrible. I noted a couple of other posts with the same issue, but did not note if anyone has found a fix.

SSB mode seems to be fine.

Is there a fix or is it what it is?

Thanks,

I have same problem with my 991,I use it on 6M AM.I left an inquiry on the yaesu website but have had no reply.
I have noticed that when transmitting the alc level is full scale no matter what the carrier level is or mic gain is set at.
Hopefully when enough users report this problem maybe Yaesu will look in to it.
On HF the alc works properly the way it should but i have have found no one to check my audio.10 is fairly dead more so on 29.0
