This is a followup to my earlier email regarding a possible
compatibility issue between WSJT-X and Mac OS 10.14.1 while using
v1.9.1 software. The issue I reported earlier was that decode does not
occur during the receive portion of the T/R sequence when ENABLE TX is
active.
I have since installed v2.0.0-rc4a891ad and have observed the same
failed decode behavior that was reported in my earlier email for v1.9.1.

DESCRIPTION OF A FAILED QSO
- On 11/17/2017 at 15:31:00 - 15:33:00 UTC a QSO was attempted with
AA7A on 14074.00 MHz offset 2823 Hz.

-- Rig: None
Hi Robert,
above I have picked out the salient points from your issue report. You
are operating with a Tx audio offset of 2823Hz without rig control, this
is a non-starter as your Tx SSB IF filter will effectively cut off your
Tx signal. If you do not have CAT control and therefore cannot enable
the "Settings->Radio->Split Operating" option that would allow this
scenario to work, then you must adjust your VFO dial frequency to
accommodate this type of QSO. For example if you set your rig's VFO dial
frequency to 14075 kHz then set a Tx audio offset in WSJT-X of 1823Hz
then to your QSO partners you will be in exactly the same place but with
no attenuation of your transmitted signal which at 1823Hz is well within
the passband of your SSB IF filter.
