Steve Franke	ed92d5a86c	SNR estimator is broken for isync=2 messages, due to different signal normalization. For now, go back to SJF's old signal/(noise+interference) estimator.	2018-07-04 16:58:24 -05:00
Steve Franke	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

Steve Franke	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
Steve Franke	91388f8ba2	Create a separate simulation program, ft8sim2, for New Style 77 bit messages. Hashes are not handled yet. Needs more testing.	2018-07-04 09:52:39 -05:00
Steve Franke	24f4792b23	Fix incorrect reference to extract77 - should have been unpack77	2018-07-03 15:59:24 -05:00
Steve Franke	c4e6a310aa	Turn off ap symbol generation for type 2 messages. This needs to be completely reworked once basic functionality is established.	2018-07-03 15:49:39 -05:00

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	cf64cad091	Send m_i3, m_n3, m_isync from mainwindow to genft8.f90 and use these to determine the type of generated message, according to the scheme described in lib/77bit/NewCode.txt.	2018-07-03 14:37:50 -05:00

Steve Franke	3f897225fe	genft8 now looks at sign of n3 and i3. If either sign is negative, generate a type 1 (classic) message. Otherwise generate type 2. Type 1 seems to work. Type 2 does not yet work.	2018-07-03 11:10:47 -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
