I like the empirical approach Paul! Your results pretty much correspond with my observations.
The softrock and sdr-core combination goes all the way down to 0Hz. I run the softrock LO with a 12kHz offset to get away from DC and the LF limit of the Delta 44 sound card. I will start logging at < 250Hz and see what happens. 73 Nick G3VNC On 08/11/14 07:36, Paul DU2/WA8UGN wrote: > Paul DU2/WA8UGN <keatipa@...> writes: >> >> I have had WSJT-X v1.4.0-rc2 (beta) decode a JT-65 signal at 183Hz on Nov >> 7, 2014: >> >> 1607 -23 -0.5 183 # UK8OAR DG5SAY R-20 >> >> 1609 -22 -0.5 183 # UK8OAR DG5SAY 73 >> >> 73 >> >> Paul DU2/WA8UGN >> >> -------------------------------------------------------------------------- > ---- >> > Follow-up information: > > Date/Time: 11/7/2014 1607-1609 UTC > Frequency: 14.076183MHz > Low-end audio cutoff (-3dB): ~300Hz > Low-end audio cutoff (total: ~120Hz > Equipment: Kenwood TS-570D > SignaLink USB Sound Card > Sony VAIO VPCCB laptop > > Cheers & 73, > > Paul DU2/WA8UGN (formerly G5BNV) ------------------------------------------------------------------------------ _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
