Builds using cmake will put the programs fmtave[.exe], fcal[.exe] and fmeasure[.exe] in the .../install/bin directory along with wsjtx[.exe] and the other executables.
To use this capability you should enter known frequencies of your calibration stations under FreqCal mode. I use these frequencies: 0.660 0.880 1.210 2.500 3.330 5.000 7.850 10.000 14.670 15.000 20.000 MHz. (The first three are clear-channel AM broadcast stations within 100 km of my location, and the others are WWV and CHU.) In other parts of the world you will use other calibration stations.
With *Measure* active, select *Frequency calibtation* from the *Tools* menu. The program will cycle through your FreqCal frequencies, measuring the effective Dial Error approximately every 3 seconds for a total of 30 s and writing the results to file fmt.ave in the WSJT-X log directory.
As things stand now (r7467), to complete the calibration procedure you need to copy fmt.all to a convenient location and then edit and process it as described here:
