Version 4 CW: Return to Receive Issue

I think I may have discovered the cause of the extended TX>RX delay, which is still apparent on 4.1.3.

In the radio set up there is a TX delay parameter. My understanding (and I think they way it used to work) is that this is a delay to the start of RF output on the RX>TX transition. Separately, in the P/CW panel there is the Delay slider, which should be the TX>RX transition delay, aka breakin delay.

I set the P/CW Delay slider to zero and noted that there was still a significant delay in the TX>RX transition. I then reduced the TX delay parameter in radio setup and sure enough the TX>RX delay also reduced. By setting the TX delay slider to 0 I got near enough full break-in.

So the TX delay value in setup is being added to the break-in delay. This I think is wrong: the TX delay should only be on the RX>TX transition, to permit relays, etc. to settle before RF is produced.

Perhaps the community could explore this further and check out my observations/reasoning.
