Modem either works with HT, or with Brand Meister, but not both.

Hello,
Setting up a personal hotspot may not be the ideal way to learn and understand DMR, but that's the backward approach I have chosen.
I have one of these (https://www.ebay.com/itm/115719226932?m ... media=COPY) on a Rpi Zero W. I have tried it with "stock" Pi-zero and currently have the WPSD version running. I have two SD cards can can jump between them. My problem is identical on both.
I have set up a call to Parrot 9990 on my HT.
Via SSH I see that I have an MMDVM_HS_DUAL_HAT-v1.5.2 20201108 14.7456 Dual ADF7021 fw by CA6JAU
What I am finding is that if I select the MMDVM_DUAL_HAT (DB9MAT, DF2ET & DO7EN) modem, Brand Meister is happy and says my device is "verified". However if I kerchunk Parrot, the screen does not light up, and the DMR beacon does not light. If however I choose the MMDVM_HS_DUAL_BAND modem, it looses connection with Brand Meister, however a kerchunk lights up the screen and the DMR beacon.
I have tested all of the GPIO options and found that there are several which work each way, but none that will work with the HT and Brand Meister.
Any input is appreciated.
