Befuddled. I noticed that the TX start on FT8 using v2.4.0 seemed late
soon after I upgraded months ago. I always felt like I had taken a step
back in performance with v2.4.0 and decided to look at into it today.

I measured the TX start delay today and it was like 4 to 5 seconds. When
I run v2.3.0 on the same computer using the same configuration I get no
detectable delay. When I use v2.5.2rc1 on the same computer with the
same configuration I get the same 4 to 5 second delay. When I use JTDX
which is based on v 2.4.0, I get the same 4 to 5 second delay. I see a
slight delay in one of the other stations in the shack on v 2.4.0 but
not as much as my main station. The main station is an i5 that with 8 G
available RAM. I have not tried other modes, but I am running v2.3.0
until I get an inspiration about what to try to address this. I get the
same delay whether I use the VOX, CAT or DTR/RTS PTT interface. The
audio starts in the TX sequence at the same time I get the command to
PTT...always 4 to 5 seconds late.

Thoughts?
