Re: VLF: 8970 in JN06ht

Hello Markus,

You may have solved the puzzle already, thanks! To the naked eye it looks like the pattern is there. I'm recording a wav file of Stefan's experiment, hope to find a way to further process it but I do need help for this.

Propagation seems to go down now, studying the MSKs signal levels for many days now, looks like the best time to receive Stefan is 10-12UTC. Nonetheless, I'm very happy for this and I do congratulate Stefan for his perseverance and for showing us all what can be achieved at this frequencies with amateur radio means only. Hope he's taking well care of himself in the forest cold out there.

Back to watching the grabber now and hopefully, decode the "special" message he's currently transmitting :-))

A very exiting day!

Hi Chris, there is indeed also a hint of the 6.47 kHz transmission. Attached is a clip from your grabber, with an inset from a Heidelberg screenshot at same scale. You can clearly make out your rows of bright pixels above the dash and the "R".

 

Congratulations, this is excellent work!

Hello Gerhard, VLF,

Yes, definitely a signal here and quite sterong also, simply unbelievable!
I think I may have seen also a trace of Stefan's 6470Hz transmission but very, very weak. Further post-processing must be applied to maybe reveal the possible signal.

Very exiting!!!

73s all,

Hello Markus !

Yes, it is Ossi but he now went down for 100mHz.

I just saw Stefans trace also on the 4X grabber !!!!!

Could you tell him?

Possibly another transmission from OE5ODL? There's a fat trace on
Ossi's grabber

I hope this is not creating confusion.

Best 73 and good luck,
Markus

Stefan has started sending an R. Low tone- high tone - low tone.

After the R he will extend the antenna from 200 to 300 mtrs. 10
minutes later he will transmit on 8970 Hz. We will report the
beginning of that transmission.
