QSK in V3

In Flex 6400, QSK works for the same antenna only for version 2.49 (2.5 did not check), and starting from 3.019 only for different ones. When you turn on one antenna for reception and transmission, QSK is immediately turned off. What is the reason?

    I use QSK all the time on 251. Works fine at 25 to 30 same antenna. Curious about feedback on V3.

    For me looks good on my 6700 with 3.0.27 https://m.youtube.com/watch?v=Du5UdmCsC5k

    Problem solved! Tim explained that starting from version 2.5 there is no possibility to work with QSK on one antenna if the ATU is installed and enabled. In my case, Flex 6400 + ATU. That was the problem. When you turn off the ATU, QSK runs on a single antenna. The question is removed!

    This is for Tim Could you share your explanation with the entire forum? I have other radios that support QSK and it doesn’t, matter wither the ATU In enabled or disabled. Does this imply that the ATU is bypassed on normal receive? Is so, why? Thanks, 73, Mark, N8ME
