Right there with you Mike on these suggestions to the WSJT-x coders.
I think this fairly rare DX Expedition with VP8PJ is a good practice
test for an advanced more expensive and dangerous DX Expedition that
would want to use F/H like Bouvet. Some hams will always blindly call
the FOX above 1000, and I even saw blind calling for hours on the FOX
slots, messing up the working slots and preventing hams from getting
their RR73. These issues are taking up cycle time for the FOX in
preventing the "Q" moving as fast as possible and Hounds from getting in
and out of the "Q" ASAP. This is the same bad behavior as calling on the
DX station's TX Freq. your ( listening Freq. ) in CW, but with CW you
can at least tell them, " UP UP" , but with FT8 you can not do that.
The Bouvet DX Expedition and other expeditions in the future using F/H
will see this wasted bandwidth and be more costly for everyone unless
the coders prevent some of these operator errors. Also, there are those
bad hams who might want to disrupt the DX operations for both the FOX
and Hounds. I hope the developers are listening and will review these
suggested improvements.

Was working with someone trying the VP8PJ dxpedition and he had a
problem that I think needs fixing.
He was pulled down by Fox to 346 and lost the path so got bumped to
646 and continued to transmit until timed out. He then went 1000 and
continued TX3 which then immediately bumped back down to 646 which he
though meant the Fox saw him.
It's this section of code....
if (m_nSentFoxRrpt==2 and m_ntx==3) {
// move off the original Fox frequency on subsequent tries
of Tx3
int nfreq=m_nFoxFreq + 300;
if(m_nFoxFreq>600) nfreq=m_nFoxFreq - 300; //keep nfreq
below 900 Hz
ui->TxFreqSpinBox->setValue(nfreq);
}
Maybe we need to add a check for TxFreqSpinBox > 999 and either
disallow anything but TX1 or if we want we to let TX3 continue (will
Fox decode that?) then we need to leave the frequency alone.
On a side note...I fully believe that we need to disable anybody
transmitting to Fox unless they've decoded them at least once (and
decoded them recently too...maybe a 5-minute timeout or less). We're
seeing people blind calling and calling incessantly that don't
understand they should not be transmitting until they see the DXpedition.
