Improved frequency calibration

Browse Source 
Measure check  box added to FreqCal  mode, check to record  to fmt.all
with  current  calibration correction  disabled,  uncheck  to see  the
impact of the current calibration parameters.

The  fmt.all  file  is  now  optionally  renamed  to  fmt.bak  when  a
calibration solution  is accepted.  This allows  users to  preserve an
fmt.all file that they might have edited for best fit.

A calibration procedure might proceed thus:-

1) select FreqCal mode,

2) step through suggested  calibration test frequencies deleting those
that have no usable signal,

3) enable "Menu->Tools->Execute frequency calibration cycle" and check
that suitable signals are present,

4) select a suitable FTol and T/R period,

5) check  "Measure" and let the  cycle complete a few  times to gather
data,

6) uncheck "Measure" to complete the data capture, optionally tidy the
fmt.all file with your favourite editor,

7) push "Menu->Tools->Solve for  calibration parameters" and accept if
you like what you see,

8) sit back and admire your accurately frequency calibrated station.
