6600 goes into transmit when keying another radio from wsjt-x

Hello

I have WSJT-x 2.6.1 running with 2 configurations, one instance only, not at the same time, one of them a FLEX 6600 (3.4.21) running via IP CAT and the other a Kenwood TS-2000 running via Com 8 CAT.

When I key the FLEX via WSJT-x everything with the Kenwood is fine (IE stays in Receive mode), However if I key up the Kenwood via WSJT-x the Kenwood goes into transmit and the Flex also goes into transmit, the Kenwood is transmitting a signal as normal, but the Flex is just in transmit mode and is not sending any signal (luckily).

Is this normal?  Is this a bug or a feature, IE to protect the Flex’s receiver? Do we think this a WSJT-x issue or a Flex issue?

The Flex is on HF and the Kenwood is on VHF 2m both in FT8 mode.

I have also tried this running 2 instances of WSJT-x running at the same time with the same result.

Also, there is no Com 8 in CAT for the Flex

PS also tried this with a Defaulted, IE reseted, instance of WSJT-x with the same result
