cb8eeba835 Add submode to argument list of JT9 subroutine decode().
Add test program fersum; several tweaks to fer65.
Code cleanup in lorentzian, and return chisqr in a(5).

ea84eaf514 Change the definition of Doppler Spread (option "-d x" used in jt65sim
so that specified spreads correspond to the full limb-to-limb spread 
for EME.  Line widths at -3 dB will be 1/3 of the specified value.

e798285479 1. Further cleanup of fer65.f90.
2. Abort if DS is requested and CALL3 is short or missing.
3. Minor adjustment of spinner size on Wide Graph.

c54831df14 1. Clean up the behavior of Avg and DS decoding.
2. Specify Navg (max # of transmissions to average) for fer65.
3. Specify DS (0 = no deep search, 1 = deep search) for fer65.

e84ce2bad1 First attempt at a smoothing loop inside avg65. Needs testing!

in simulation tests.

846ddf9039 1. Clean up GUI features releted to message averaging and deep search.
2. Make averaging and DS separately selecteble.
3. Clear nftt and avemsg on Clear Avg.
4. Allow fer65 to handle message averaging.

767a9452e6 1. Use Lorentzian profile for smoothing (but not yet for message averaging).
2. Add ability to set ndepth and do message averaging ti fer65.
3. Correct SNR values for measured Doppler width.
4. Comment out the "write(62..." diagnostics.

533bb81220 Various changes to JT65 decoding, all potentially temporary.
1. Measure Doppler width by fitting a (modified) Lorentzian.
2. Don't call "slope" in sync65().
3. New definition of "sync1".
4. Get snr from sync1.

9f388b63dc Many changes in aid of decoding signals with significant Doppler spread
in submodes JT65B, C.  More changes still to come!
