We'll probably need that technique in the toolbox for ULF. > f = 6470.00000 Hz > Start time: 11.11.2016 08:00:00 UTC (Daily repetition) > Symbol length: 60 s > Characters: 4 > CRC 16 > Coding 8K19A That's a good plan. Hopefully strong enough to decode each day individually. I tried some stacking of days and nights during your epic 828.25 hour carrier at 2970 from June/July. Soon I hope to do continue work on that long recording. I have a new scratch disk to install in my PC which will speed up processing of the 459.85 Gbyte data set (35 days 3 channel flac compressed). Now it is winter I look forward to spending more time on that. -- Paul Nicholson --
