Hi Sandro,

in the WSJT-X MainWindow class there is a member variable m_bSimplex, 
when set to true it disables the Tx frequency and tone offsetting that 
is used to cover the necessary bandwidth for HF JT9+JT65 operation. It 
looks like it is not being set for the "fast" modes where it should be. 
Setting "Settings->General->Enable VHF/UHF/Microwave features" to 
checked should also turn off the unwanted behaviour.
