If I remember correctly, the KX3 can show zero bars when
overdriven. I's easy to check. Just bring the level up slowly
from zero and check that the ALC rises slowly.
Remember that there are at least 3 AF level controls. The one in
the program, the OS level control, and the knob on the KX3.
I don't know why any of them would change suddenly though.
An external RF power meter or another receiver can check if you
are transmitting.

I have been operating with FT8 and WSPR lately. Both use an audio-generated
digital signal just like any AFSK mode. I tune up my transmitter to show
4-5 bars on ALC. Everything seems to work at first, but after one or two
transmissions the display shows only one bar on the left and one on the
right -- and if I move the Mic Gain, all bars disappear leaving a blank
display. The transmit light stays on but I can't tell if I'm transmitting
any audio or not. What's going on??
thanks,
