Unid FSK system heard around 1005z on 8800 KHz (cf +1200Hz) running at 400 Baud and 800 Hz shift (Figure 1). Unfortunately I went late on the signal so I missed the initial part of the transmission which could have provided more details useful for identification (at least the encryption, if any).
Running the cross-correlation function, KarapuZ noted spikes at ~4007 msecs (Figure 2) that could mean a period of about 1600-1608 bits length. Hope to catch a complete transfer, but it will not esay.
