Hi Mike,
Try this…in mainwindow.cpp replace stopTx2() with the following. It
defers the frequency change for 2 seconds which is probably too long
but succeeds in moving ptt=0 in front of the frequency change.
If you follow the code from MainWindow::WSPR_scheduling() through
MainWindow::on_bandComboBox_activated() -> MainWindow::band_changed()
you will see the line:
Q_EMIT m_config.transceiver_frequency (f);
this just like the line:
Q_EMIT m_config.transceiver_ptt (false); //Lower PTT
is queuing a Qt signal which eventually crosses the thread boundary to
the transceiver control thread. These signals are processed strictly in
the order they are queued. So your assumption that the above lines are
processed in the wrong order is incorrect.
