VE.Direct MPPT 75/10 high amount of checksum errors / corrupt checksum packets

MTTP 75/10 latest firmware version FW 161 connected via a 5v FTDI cable getting about 25 bad packets every ~200 good packets. The corruption appears to always be in the checksum field not random like noise. Baud is 19200, tested with custom software & also happens with simple Com Terminal app.

Is there a known issue with how checksums are being calculated in this version of FW?
Anyone else experiencing this? Since it is always on the checksum field I'm pretty doubtful this is a comms issue?
