Thanks Paul, good to see.
I tried various time and frequency offsets for the wav file from last night and for the stacked file from the last two nights. No result.
Now i started two SpecLab instances on the RX site, one is using PPS+NTP, the other one DHO38. During the transmision time, DHO38 has a good strength and no terminator is passing, so maybe it will give better results, at least it will be interesting to compare.
Since i want to avoid false decodes, i changed the parameters and will try 2 characters again. Tonite:

f = 8270.1000 Hz
Start time: 09.November.2017  16:00:00 UTC
Symbol period: 60 s
Characters: 2
CRC bits: 15
Coding 16K21A
Duration: 12:32
Antenna current: 620 mA

73, Stefan

Yes, a strong signal here and perfect decode of the 3 chars:

            H-field           E-field             E+H field
 7th/8th  10.5 dB 99.8 deg   9.0 dB 107.3 deg   12.5 dB 103.3 deg
 8th/9th  14.1 dB 88.3 deg  12.5 dB  93.8 deg   17.3 dB  90.9 deg

Signal phase repeated fine both nights.  Given the S/N of your 2 char
success, you would be very lucky to do 3 chars in one night, but two
nights ought to do it.
