Hi all,
WSJT-X v1.8.0-rc1 includes an optional feature that is a significant
departure from all previous WSJT-related software.
When you call CQ in FT8 mode with both "Auto Seq" and "Call 1st"
checked, the program automatically selects the first decoded response to
your CQ and starts a QSO with the selected station. The effect is the
same as if you had double-clicked on the caller's message. Subsequent
transmissions will then continue automatically through the standard QSO
sequence.
When the contact is complete the CQ message (Tx6 on Tab 1) is selected
but "Tx Enable" is turned OFF. This choice is intentional. We want
WSJT-X to be a tool for assisting contacts between human operators, not
an "Automatic QSO Machine".
For a mode with 15-second T/R sequences and very little time for
selecting reply messages, there are obvious merits of the approach we
have tentatively adopted. However, there are also some obvious
consequences that might not be considered desirable. Do we want a
computer algorithm to take part in choosing our QSO partners?
It seems like a good idea to have some public discussion on whether
"Call 1st" already goes too far in the direction of QSO automation.
Some of you noticed that a "Weak" box appeared briefly beside "Call 1st"
(but was not yet implemented). The idea was that when two or more
replies were received to one's CQ, this option would select the one with
lower S/N -- potentially encouraging people to keep their power turned
down, as appropriate for conditions.
We are interested in feedback from users on the question of partial QSO
automation. Should "Call 1st" be changed or removed?
One more point: FT8 signals occupy the frequency/time plane more
"densely" than JT65. For this reason, even when we have implemented
signal subtraction and multi-pass decoding, overlapping signals will be
less likely to decode than is the case with JT65. You may soon discover
that it often pays to respond to a CQ "off frequency" by 60 Hz or more.
We might consider offering a tool to make this easier to do.
