This discussion started out as a question as to if the auto sequencer could
respond to a specific non standard message and I digressed it. My
apologies.
Back to that original question... I pseudo coded the WSJT auto sequencer
in
order to document it in the manual. One of my projects is looking through
the
JT9 auto sequencer to see if there are any improvements to be made either
to either the ISCAT one or the JT9 one. This is the pseudo code as it
exists now...
if TX Auto is checked and Auto is On
if Current TX Sequence equals TX1
if Received Message equals valid TX1
Set Signal Report
Advance to TX2
else if Received Message equals valid TX2
Set Signal Report
Advance to TX3
else if Current TX Sequence equals TX2
if Received Message equals valid TX2
Set Signal Report
Advance to TX3
else if Received Message equals valid TX3
Advance to TX4
else if Current TX Sequence equals TX3
if Received Message equals valid TX3
Advance to TX4
else if Received Message equals TX4
Set TXStopCount to Auto73Count
Advance to TX5
Set Log QSO to blink
else if Current TX Sequence equals TX4
if Received Message equals valid TX4
Set TXStopCount to Auto73Count
Advance to TX5
Set Log QSO to blink
else if Received Message equals valid TX5
Set TXStopCount to Auto73Count
Advance to TX5
Set Log QSO to blink
else if Current TX Sequence equals TX5
if Received Message equals valid TX5
Set TXStopCount to 0
Set Auto is ON to Auto is OFF
else if Received Message equals valid TX4
Set TXStopCount to Auto73Count
else
Decrement TXStopCount
if TXStopCount equals 0
Set Auto is ON to Auto is OFF
As you can see the auto sequencer is highly situational and the end game,
when to
quit transmitting gets a little complicated. There is an inherent catch 22
that needs
to be dealt with and is to some degree in the pseudo code. The reports I
had during
the ISCAT craze this summer was that it was working OK.
The RR73 question really boils down to can the statement
if Received Message equals TX4
be modified to also recognize RR73 as a combined RRR and 73. The answer is
obviously yes
however in the context of the auto sequencer that really does not change
much. The
end game still needs to be played out so the station that sent RR73 is at
some point
going to need to send a 73 anyway for things to gracefully stop under
automatic
control.
Assuming we were to recognize RR73 as a valid RRR what else do we recognize?
I have
seen variations of this such as R73, 73RR, etc. This gets a little
complicated and
someone will be left out.
Also a practice I have seen repeatedly is that of skipping the TX4 message
completely and going straight to TX5. Should the auto sequencer recognize
that as
valid?
My point, and my opinion for what it is worth, is that the auto sequencer
should not
be in the business of attempting to recognize an infinite variation of
possible
non standard messages. That would be a programming nightmare. Once
WSJT(x)
is set up with proper from and to calls (and possibly grid) the messages
recognized by
the auto sequencer should be "by the book". If the book changes, then and
only then
should the auto sequencer change.
Does this mean non standard messages are not allowed? No, it simply means
they need
to be dealt with manually. That leaves it up to the operator to decide if
a non standard
message meets the QSO criteria for their station.
73 de Bill ND0B
by the auto sequencer should be fixed based on those standard messages.
