a448dc5640 Use 37 character message for de-duping. Comment out some code that needs to be updated to work with new message type. 2018-07-04 16:20:12 -05:00

df652e383b More progress on making ft8sim2 and ft8b_2 encode and decode all message types. For now, decoder.f90 is hardwired to always print 37 characters. 2018-07-04 10:15:01 -05:00

57ebc30369 Call the new extract77 in ft8b_2. Define msg37 and msgsent37 to replace their 22-bit predecessors. 2018-07-03 15:34:39 -05:00

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

03abada09b More progress on sequence demodulator. Can now do nsymb=1,2, and/or 3. 2018-06-26 11:11:58 -05:00

7684bd0e78 Work toward a generalized sequence detector for nsymbols=1, 2, or 3. Works for nsymbol=3, but not yet for nsymbol=1, or 2. 2018-06-25 17:01:34 -05:00

0f5759270e Added 2-symbol sequence detection for proof-of-concept tests. 2018-06-22 11:20:28 -05:00

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

a5837bd5c7 AP decoding now works for type 2 frames. Also cleaned up and simplified AP implementation in ft8b_2. 2018-06-11 15:10:44 -05:00

a0db6a8a08 Disable AP passes for type 2 frames, for now. Write some diagnostics to lun 81. 2018-06-07 11:40:25 -05:00

a23e2b6f8b Fix a bug that caused some second-decoding-attempt log-likelihoods to become NaN. 2018-06-06 11:21:00 -05:00

48b60eab71 Make two sync passes, one for each sync array. Label candidates with their type and decode accordingly. 2018-06-05 16:44:52 -05:00
