Thanks Joe.  That's what I suspected, but its better coming from someone who
actually knows.

Happy to hear that you like the new capabilities for Frequency Calibration.

As for removing "bad data" from the file fmt.all: with a bit of accumulated
experience, your own judgment will continue to be the best guideline.

Data in the file look something like this (I have added the headings and
separator line):

   UTC  Freq CAL Offset  fMeas   DFLevel   S/N
   (kHz)  ?  (Hz) (Hz)  (Hz)(dB)   (dB)
--
14:35:09660  1  1500  1500.890 0.890  -11.6   19.2  *
14:35:11660  1  1500  1500.861 0.861  -16.4   39.7
14:35:13660  1  1500  1500.859 0.859  -18.7   42.2

For each calibration-station frequency "Freq" (here 660 kHz), the measured
audio frequencies "fMeas" and frequency offsets "DF" will typically agree to
within 1 Hz or better -- usually *much* better. 
Delete any outliers.  Measurements with estimated S/N less than 20 dB will
be flagged with an asterisk.  These are worth examining individually,
because they might be bad.  The one flagged above is OK.

Hi Mike

Yes, thanks that worked fine and was able to then revert back to 5.5 with
no problems.

Thanks for your help.

Does anyone have still have means of building an installer using Qt5.2?

I switched to 5.5 some time ago and don't want to risk going back to 5.2.

Hi Dan,

I also have a question.  The FMT analysis program initially had an error 
and referred to bad data.  The online manual does say to edit the 
fmt.all file and remove bad data.  I did that and the analysis ran 
without error.  I made a judgement call as to what constitutes “bad 
data”, in this case anything more than 1.9 deviation was bad.  Is there 
a better rule of thumb for “bad data”?

Hi All

Does anyone have still have means of building an installer using Qt5.2?

I switched to 5.5 some time ago and don't want to risk going back to 5.2.
