Weak, SIO 222 or so, with music, still going at 2341.
I checked the SDR recording, it was on until 0042, and yes on 6934.9 kHz. Starting around 0030 there were some tones at 1 kHz, but there did not seem to be any information in them. At least not anything I could find, didn't seem to be CW or PSK31 anyway.
