After some communication with Laurie on JTAlert we have started down the path of integrating WSJT-X a bit more.
The idea is that WSJT-X should have a UDPServer that can receive commands to
do things so, for example, one could double-click on a JTAlert entry and it
could command WSJT-X to do its thing.
To this end I started coding one but am having QT class problems that are
befuddling me and was hoping someone (Bill?) could assist.
So far this implementation is intended to just take a "CQ" decoded message
and put it in the "Rx Frequency" window. Then I was going to add the
double-click action once the first was working and stable.
I got this somewhat working but debugging complained about sending signals
when I just threaded a function inside then mainwindow.cpp plus gui stuff
isn't thread safe.
So I made the udp server a separate class and started trying slots/signals.
But now connecting the slot/signal burps on compiling and I can't quite
figure out the magic incantation to make it happy.
This is the line it complains about on MainWindow::doCall
connect(m_UDPServer,&UDPServer::on_doCall,this,&MainWindow::doCall);
doCall is declared as a public slot in mainwindow.h and defined in
mainwindow.cpp

Here's a UDP client to work with it that just cycles through a few CQ
messages. All being done on port 5001 right now.
