Cut-off frequency band of the transmitter in FM

Welcome all! My question is why in the NFM and FM transmitter has a cut-off frequency response! From 300 Hz !!! There are completely no low frequencies that are in SSB and AM. FLEX sounds like it’s the cheapest CB radio to transmit to FM. For this reason, it makes no sense to use an expensive microphone with a wide frequency response. Is there any way to fix this? I want my FLEX in FM to work just as beautiful as in SSB and AM. For this, I cut audio in FM I don’t understand.

    With my 6400 running 2.4.9 I can set the transmit low cut frequency anywhere I want in NFM or FM mode. I do not see a fixed low-cut frequency.

    With the release of each new firmware, good functions disappear. For example, the 27 MHz transmitter fails! And on the old firmware, I could work on flex in the CB range. And today at 29 MHz I saw that I have a transmitter in FM trimmed sound.
