Alternate PTT Logic: activate slightly different program logic for controlling your T/R 
switching via the COM port. (A few combinations of hardware and operating system 
drivers seem to work better with this option checked.) 
Tx Mute: mute the transmitter. Use with Auto ON to monitor one side of a QSO. 
Enter new “To radio” callsign: clear the To radio and Grid boxes in preparation for 
new entries. 
Tx Stop forces Auto OFF: if this item is checked, clicking TX Stop during a 
transmission will toggle Auto to OFF. 
Mode 
Select desired operating mode from this menu. 
Save 
Save Decoded: save any files producing decoded text in subdirectory RxWav under 
your WSJT home directory. 
Save All: save all recorded files in subdirectory RxWav of your WSJT home directory. 
Band 
Select your operating band from displayed list. The selected frequency is used for 
computing EME Doppler shifts and sky background temperatures. 
Help
