Keying Delay when using Flex 6400M + HRD + WSJT-X
David DeVos KF8QL

As recommended I have WSJT-X connect to HRD, and then HRD connects to the Flex 6400. I did this to use the HRD alert function which shows me what contacts are new to me.
The problem is a over 1 second delay from the time I see WSJT showing Tx to the time the radio goes into transmit. This is bad on FT-8, but I've been making contacts. It's REALLY bad on FT-4 because of the shorter transmit time.
I'm using BktTimesync for my PC clock, and that is working well. But I don't understand why I'm getting so much delay!

OM David,
Open CAT application and create PTT type COM port. Note its number.
Open RADIO setup in WSJT-X and in PTT settings select this port and select RTS.
You can also activate VOX in SSDR and select it WSJT-X RADIO setup, but I found it not very stable and responsive at times.
I very much prefer JTDX improved version rather than WSJT-X.
Tom
