Hi Terry,

wishing all the best for 2017 to you as well!

Joe's example files are available on his website: http://www.ucs.mun.ca/~jcraig/ebnaut/

Yes these are the same files which are used for opds. To keep them, you only have to remove or circumvent the auto-delete command in cleanup.bat. However the \data directory shouldn't grow very large because opds periodically scans it for new entries. My cleanup.bat has an extra line to copy the files to a separate "\saved" subdirectory before deletion:

@copy headline.txt + detected.txt + detecold.txt c:\dropbox\public\opds32.txt >nul
@copy c:\spectrum\data\*.txt c:\spectrum\data\saved\*.txt 1>nul 2>nul
@del c:\spectrum\data\*.txt 1>nul 2>nul
@copy dirw.txt dirdone.txt >nul

It is helpful but not absolutely necessary to use GPS lock for the audio. The audio frequency is low enough (typically 1.5 kHz) that sub-ppm samplerate deviations have relatively little effect. Alternatively, you could also use an injected audio carrier (e.g. 5.000 kHz) for SpecLab's samplerate corrector. For the purpose of file timestamping, controlling the PC clock with NTP is sufficient.

I believe that your questions may also be relevant to others, so if it's ok with you I'd suggest posting this to the LF group.

All the best,
Markus (DF6NM)
