No signals were received before 1930 utc, but around that time I saw a strong carrier on 137.5kHz on the spectrogram, followed by a broad noise-like trace with the appearance of a BPSK signal, with an SNR of a few dB in 0.12Hz bandwidth. Running Wolf on the resulting recording immedeately resulted in the "TSTIK5ZPV" mesage being decoded. Indicated frequency drifted from 0.2 - 0.3Hz below nominal over 25 minutes In fact, if the signal had been any stronger, it would have been neccessary to attenuate it to avoid overloading the Wolf software, so Valerio could probably reduce power by 10-20dB and still be copied easily here under similar conditions.
