T/R Relay noise with Antenna Tuner - 6600

Normally CW is silent, no relay noise at all. However, I noticed that when the internal Antenna tuner is active on the 6600 there is a T/R relay clicking when sending CW. It is a very noticeable difference with the tuner on and off. Is this normal, or is there a setting somewhere I have overlooked?

Thanks!

    QSK with ATU engaged is not supported unless using a separate receive antenna. This is documented in the 3.0.19 user manual. Where you using QSK?

    The QSK enunciator is displayed with the tuner activated on a single antenna, so I assumed it was supported. Apparently this is not the case. I would much prefer that the tuner stay inline for receive to allow for CW QSK, but it is what it is.

    Thanks.

    Flex sites potential performance issues when using QSK with single antenna with ATU engaged. I agree this is undesirable but I’m afraid this is how iQSK works with Flex. I did find a workaround but not sure it will work in V3. Try to change to another band then back . That forces QSK to work with ATU on my 6600M running 2.49.
