For decoding FT8 and some other modes the JT9 binary from the WSJT-X
package can be used. It can process WAV recordings.
Is there a possibility to do that for the MSK144 mode as well?
Background: The very nice openwebrx fork from dd5fjk can already monitor
FT8 in the background and monitoring 144.360 in MSK144 would be a very
useful thing.
The current structure of WSJT-X invokes a separate process jt9[.exe] to
decode any of the "slow" modes. Such decoding takes place at the end of
a receive sequence. In contrast MSK144, a "fast" mode, is decoded
within the main wsjtx[.exe] process itself.
In principle there is no reason why a command-line program could not be
written to decode MSK144 signals. The necessary processing starts in
Fortran subroutine mskrtd.f90. This routine and all others required are
available in the source-code tarball.
