Here are my recordings of the SAQ xmas transmission:
Raw data where recorded with the DR-40 recorder and then demodulated by using the SAQ receiver preset of Spectrum Lab.
I tried to do some frequency measurements with the sample rate calibrated with other VLF stations.
As a result I got 17.188 KHz
Thanks for the great work you are doing to keep this unique system going.
Happy Christmas and a good 2016!
