2345 no signal here (also no signal on a bunch of Kiwi SDRs)

edit : the station probably closed down before 2345

late edit : tentative Mystery 21 (reported on 4870 earlier)

Strange, I logged this station between 2315 and 2335 UTC with the Airspy HF+ Discovery on the HFDY loop and  with the Sony ICF-2001 D on the Grahn, so an artifact is unlikely. My equipment is not to sophisticated, so the Kiwis nearby should have no problems. I will check back this evening.
