Steve Franke	b993935494	Reconfigure foxgen.f90 for 77bit messages. Fox now transmits only 77bit messages.	2018-10-04 17:47:36 -05:00
Joe Taylor	6cecef42aa	Restore a missing call to unpack77().	2018-10-04 16:09:02 -04:00
Steve Franke	d9cf9bed3c	Better handling of decodes with unhashed callsigns. ... (cherry picked from commit 3b783a083e)	2018-09-28 17:07:28 -05:00
Joe Taylor	653e53b125	Apply the fix for i3, n3 before calling pack77() in genft8_174_91.f90.	2018-09-19 11:48:30 -04:00
Steve Franke	642540ff8f	unpack77 now returns logical variable unpk77_success, which will be .false. if there is something obviously wrong with the message. Still to do: set the flag if the unpacked message contains CQ in an implausible place.	2018-09-12 15:06:26 -05:00
Joe Taylor	ca2c1a2b8b	Don't use "appendage" ~ or ! on decoded lines. Protect against bad read in genft8_174_91.	2018-09-02 18:55:13 -04:00
Joe Taylor	2c5dd053f3	Don't send "mygrid" where it's no longer needed.	2018-07-11 16:32:08 -04:00
Joe Taylor	d95d2df5b6	Old-style "NA VHF Contest" mode removed from all Fortran routines.	2018-07-10 15:09:42 -04:00
Steve Franke	42f75bf404	Fix graymap.	2018-07-07 08:18:31 -05:00
Steve Franke	5948b671eb	Still working on getting c++/fortran interface right.	2018-07-06 18:14:56 -05:00
Joe Taylor	e5e81e01fb	Make packjt77 into a module; move all its routines into file packjt77.f90.	2018-07-05 14:07:17 -04:00
Steve Franke	bb12c7424d	Module packjt77.f90 includes the 77bit utility programs called by pak77 and unpack77. Modify genft8_174_91.f90 to generate type 2 messages.	2018-07-03 15:08:38 -05:00
Steve Franke	c39dd63f79	Send (i3,n3) from mainwindow to genft8. First steps at interpreting (i3,n3) to send itype=1 for classic messages and itype=2 otherwise. Very buggy at this stage.	2018-07-03 09:28:16 -05:00
Steve Franke	3f8c218ebe	Make changes to ft8b_2.f90 to accommodate the new 77-bit in/out encoding/decoding routines. With these changes, WSJT-X decodes (174,91) frames.	2018-06-17 12:11:32 -05:00
Steve Franke	6fe9e8f860	Remove the need to re-order the parity-check matrix columns for compatibility with the generator matrix. Redefine the codeword to have the form [91 message bits|83 parity bits].	2018-06-09 13:05:11 -05:00
Steve Franke	68beed88a7	Change to Gray bit to symbol mapping for (174,91) messages.	2018-06-08 16:21:21 -05:00
Steve Franke	772b1bd5fa	ft8sim can now generate old (174,87) or new (174,91) frames. Frame type is selected using the itype command line parameter.	2018-06-05 08:40:00 -05:00
