Tuned it at 0004, CW message. Sounds a bit like the same brief thing is being sent several times. Into music. Tough copy here.
0005 more CW, then apparently off

 :(  I believe we have a solar flare and a radio fade out. I am hearing almost nothing HF and arctic flutter on super stations. ::)

No solar flares. We haven't even had any sunspots at all for days  ;D

It's just low solar activity leading to low ionization and low foF2 values. Head down to the lower bands for DX.

p.s. I checked the SDR recording for this transmission - nothing heard here.

 :D You are so right. I think that's why engineers really stopped designing serious communication networks on HF right after WW2, except VOA and USSR began to play radio wars on shortwave with 500kw (God Forbid ) transmitters in sixties.
Today VOA a ghost ship except to attempt to blast away a socialism in Cuba. LOL The Radio Martii, what a JOKE.
