I noticed the 6950 station was back again, noted starting at 0604z on the SDR recording, with alternating mark/space frequencies. Weak signal. 6834 came back on at 0615z with a much stronger signal, just a carrier. 6950 went into traffic at 0629z, and went off the air at 0731z. 6834 went off the air at 0851z.
There seems to be yet another related station around 6990. It faded in with RTTY around 0553z Went off at 0823z.
