Steve Franke 6dbaa28a01 Fix DT search range so that it includes DT= +/-1.0. 2019-05-24 20:11:20 -05:00
Steve Franke 883c914d29 Make DT=0 mean that the first full symbol starts at t=0.5s. Formerly DT=0 corresponded to the beginning of the ramp-up symbol. Fix a bug that caused signals with large DT to wrap around instead of truncating them. 2019-05-24 20:09:00 -05:00
Joe Taylor 2ab4b59d88 Fix ft4sim_mult for 7.5 s T/R sequences. 2019-05-23 14:06:00 -04:00
Steve Franke 932e100a2c Update jt9.f90 to account for changes to FT4. 2019-05-23 09:55:50 -05:00
Steve Franke a9623703b3 FT4: Change Fortran code to NSPS=576 and make necessary accompanying 
changes on the C++ side. Basically works except that Tx audio has
incorrect DT and audio is truncated at the end. Also, command line
decoding using JT9 is not as sensitive as decoding from within WSJT-X.
