Hi folks,
I'd like to revisit this topic. I do agree that working split does
increase the success rate. However I'm constantly needing to click the
Halt Tx button when the CQing station answers another station. The
reason as I see it is that the Auto-sequence stop only follows the TX
(RED). In my opinion it should follow the RX (GREEN) indicator on the
waterfall.

Hi Rich,
I do run with the "Lock Tx=Rx" box UNCHECKED for the most part as
well. That's why I was surprised by the behavior. The green (receive)
is right on the caller and the red (tx) is let's say 100 above. I
guess I just made the assumption that it would disable based on the
green receive frequency.

Ron,
As long as your signal frequency is within plus or minus 50 Hz of
the station you are calling, the red "Enable Tx" will be disabled
and go grey when you decode the station you called replying to
someone else. However, when your signal is 51 Hz or more either side
of the stations frequency, you will continue transmitting during your
TX sequence. When your transmitting frequency is outside the decoding
window for the nominal 47 Hz wide signal, the QRM problem to the
decoder is greatly reduced.
Operating more than 50 Hz away from a station that you are calling
will increase your chances of being decoded by that station. The
majority of stations calling a DX station are probably operating zero
beat right on the DX station's frequency and as a result the DX will
probably not decode any of them.
Running split with the "Lock Tx=Rx" box UNCHECKED for the most part,
I've been able to work 111 DXCC countries in the 4+ weeks that I've
been running FT8 on the HF bands with low power (50 to 80 Watts).
Just double click on the DX station callsign, find a quiet
frequency, then Shift-click on it and your chances of working the DX
will greatly increase.
