Some DXers report slightly reduced audio gain on weak AM signals in the newer USB-C models compared to the original. Common "Bugs" and Hidden Fixes xhdata d-808 firmware update

Preparation

• Your radio works fine (if it isn't broken, don't fix it).

• You are impatient. This is a 15-minute process with a steep learning curve.
