Something to keep in mind about the HMN1090 mic, guys:
- As you know, it was designed for the XTL. It's optimized for the IMBE codec's frequency response/codebook. This goes back to the Spectra days, when the HMN1052A was determined to sound like ass on P25, so
Moto reworked the frequency response and released the HMN1080A.
DMR uses the AMBE+2 codec. I would imagine there are many things in common between IMBE/AMBE+2, but there may be differences/enhancements between the DMR GCAI mic and the HMN1090 XTL mic.
Then again, if someone can confirm the HMN1090 is used/sold/marketed with the APX mobiles, it might give confirmation it would work/sound just fine on DMR as the APX mobile supports P25 Phase II, which also uses the AMBE+2 codec.
Just throwing it out there.
