Both gooseneck DYN mics gave 90% AM modulation with my previous BECKER

With the KRT2, the modulation lays well beyond an acceptable level. On
MIC-setup, when AUTO MIC-detection is selected, the 'MIC: dyn/std'
display answer seems quite unstable.

I can't help there. My mic (a Monacor DMG-400) is showing consistently as
'std' on the AUTO setting. I haven't had any complaints about the
transmission quality so far.

As far as I know, your Monacor mic is dynamic, not standard.
Which would confirm that the AUTO detection (display at least) is not
reliable, even if it interfaces correctly with the XCVR.
I wonder on what basis they detect it? Resistance, impedance?
All this is a bit confusing. Over the years, I got used to
generations of DITTEL radios with proverbial clear manuals.
That was before the microcontrollers and the sometimes 'fuzzy logic'
of firmware ;-) .
