I have an Anytone 878 that probably needs to be replaced because the BER jumps all over the place. But when it's low and should transmit and receive, I can't get my duplex hat to work. I've set the frequencies with a 5.0 Mhz offset and reversed the TX and RX frequencies in the CPS. I've also selected "dual slot" for "DMR Mode" and set my channels (all Brandmeister for now) to TS2. When I key up, my transmission appears on the dashboard, but I receive no audio and apparently aren't sending any either. I've been trying to get this to work for weeks and have tried different duplex hats with different Pis. And yes, my BM security password is entered. Any help appreciated. This has been keeping me up nights trying to figure out what's wrong. Screenshots attached. THANK YOU!

Also of concern...

Your may want to try "Repeater" for DMR MODE

AT-D878UV manual:

another radio with opposite TX/RX frequncies.
Repeater: Enable talk with other radio by repeat frequency throught
repeaters.

communicate by the slot set in simplex mode.
Note: If DMR mode not choosed Doulbe Slot, the radio will work on Slot in
repeat mode. if choose Double Slot, it is necessary to Double choose a slot
by time slot setting.
(23) Slot Suit
Turn on Slot suit, the radio will receive calling from both slot, and will be
able to call back in corresponding slot.
