In options TX DIGU set offset to 0

follow page 45 in the updated manual

UMA has been updated to version 6.12 www.dropbox.com/s/lhvwwuyuxpoq7gs/Expert%20Electronics%20Addendum.pdf?dl=0

otherwise as i suggested in the email request you sent : use V2.2.156 32A of JTDX, and you can avoid most of if not all of the issues you are having

experimental branch of JTDX with 32-bit audio stream support.

This experimental version of JTDX is dedicated for trial in setups with very low noise environment on overcrowded bands and receiver path IM3 dynamic range greater than 90dB.
In SDR software WDM KS or better driver shall be used, virtual audio cable shall be configured to support 32-bit audio stream.

32-bit audio device shall be used if analog linear AF output of receiver is connected to sound card.
