Joe Taylor 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.

Joe Taylor 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.

Joe Taylor 0224e76c44 Change the definition of "d" so that width of generated tones is equal
to the requested Doppler spread.  Previously they were wider by the 
factor 2*sqrt(log(2)).

Bill Somerville 4de778c4e7 Reverting r6531 and replacing with correct fix
The WSPR  message is unpacked  into a symbol  per byte array  which is
processed  by  encoding a  whole  number  of  bytes of  message,  this
requires the output  array to be bigger than the  number of symbols to
accommodate  extra values  that are  not part  of the  message due  to
rounding up to whole bytes. I.e.  176 (11*8*2) elements to contain the
162 symbols.

Bill Somerville 9e55d08eb6 Reset eliding of duplicate UDP messages if a Replay message is received
UDP message servers will not receive  a Status until some status field
changes if  they join a network  with existing clients. To  avoid this
receipt  of a  Replay message,  which should  be the  first message  a
server sends  after negotiating the  schema, now cuases  the duplicate
message check  to be  disabled for  the next  message. This  should be
sufficient for servers to get into sync.
