Many changes to the procedures for selecting decodable candidate JT9 signals. This code may be the new benchmark? git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@3274 ab8295b8-cf94-4d9e-aec4-7959e3be5d79 2013-05-16 16:02:00 +00:00			`subroutine chkss2(ss2,freq,drift,schk)`
Added routine "chkss2" to test sync vector for sanity before attenpting Fano decode. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@3270 ab8295b8-cf94-4d9e-aec4-7959e3be5d79 2013-05-15 15:17:36 +00:00
