Review on 🔥 ApplianPar UHF/VHF MMDVM Hotspot OLED and Antenna with Case: Supports P25 DMR YSF for Raspberry Pi by Damon Atonyo

There were no instructions on what to do about it. Thank goodness for UTUBE. There's a lot of useful stuff in there. I ask a question which modem should I choose in Pi-Star. Not a good answer. I found that STM32-DVM/MMDVM_HS-Raspberry PI HAT (GPIO) is working. I bought it to replace the one I ordered which was fully assembled and broke down after 2 weeks. So I figured it would work with the micro card I had. Not so. So I ordered another microcard, downloaded the latest Pi Star software and set it up just like the old one. First thing I found out is that it doesn't work in the 446 series. When I moved it to the 444 series it worked great. The Amazon site says the offset should be -475. That is not right. Mine works fine at zero offset. Other reviews said the case cutouts weren't aligned, but mine didn't have this problem. I had to cut the pins for the display at the bottom of the hat so they don't touch the pins on the Pi Zero, wh. It worked for me for 24 hours with no issues other than configuration confusion. The seller can only be contacted by email through Revain. Let's say 2 days response until it worked. So you are on your own.
