LF: TF-grabber

[Halldór <halldorgudmunds@simnet.is>]

Hi all,

 

My grabber has been offline for the last 24 hours. The reason was that I wanted to do some HF-work, I am using the same antenna for HF and LF.

I have not been reading my LF-mailbox until this evening.

So after some QSO´s on 10 meters the grabber is back online. I might have done some minor damage to my LF-antenna matching arrangement so the grabber might not be with full sensitivity, let’s see what I grabb this night.

 

By the way, I should have a copy of all the windows on my second PC at work if needed for some comparison work.

Please let me know if someone is interested.

 

Happy new year to you all

Thank you very much Stefan and Martin! When I noticed the traces coming through to Isla de Margarita it was 3h local, and as you can guess I didn't want to go to sleep but kept watching Martin's uploads for another couple of hours.

 

Attached is a comparison of the YV reception to a capture from YO/4X1RF in Bucharest. Radiated power from here was about 0.6 W ERP.

 

This afternoon I had to take the antenna down in a hurry due to sudden gusts of wind. But now it's back up and doing its thing again on 136172.5Hz... LF can be addictive can't it?

 

73 and best of luck to all,

Hi Markus, Martin, Jay, Dex, Joe(VO1NA), LF ;-)

Yes, it is amazing!
I just take a look into the archive and found these images very impressing:
https://www.dropbox.com/sh/1hi4j5gh7fqne2p/Yv4rniVU3K#/

The are signals of

WD2XNS  (35 dB SNR in 22 mHz, i.e. no problem for QRSS-3!)
VE3OT (MP)
WD2XKO and
VO1NA

and in the EU Band

DF6NM
DK7FC

Markus, congratulations to that 7995 km distance! I would confirm that the traces are yours. But maybe someone of the other grabber runners can confirm that the NM appeared during my C-D. Maybe TF3HZ or YO/4X1RF or G4WGT saves the images??
This is the 2nd EU-SA one-way reception and it has to be mentioned that you're below 1 W ERP. So it is not impossible for other stations to make that distance, especially the UK stations could have a certain advantage over JN49/59.

I think we can say we have learned that the path from EU to the north of SA is best in winther (not in spring or fall) :-) Local QRN in Venezuela due to the summer period in the southern hemisphere does not over-compensate the good propagation in the northern hemisphere to that time.

Well, who is the next one? :-)  Again, congratulations to all involved!

Stefan,

 

indeed! Now at 3:20, Martin's grabber has excellent copy from XNS, WD2XKO, NA and DK7FC (with Jay being well visible in the wideband plot). And I think I am also seeing very faint traces of an NM, exactly 0.5 Hz above Stefan's ..C D.. at 1:44 to 1:49.

 

Best 73,

LF!

This is your chance! This night appears to be VERY quiet on the
Venezuela grabber,

DCF-39 is as strong as never seen there in this year, reaching > 30 dB
in 1 Hz!!!!

I will switch to DFCW-90 on 136.172 kHz very soon.

Will someone join in? A pity if not. Where are the active UK stations?
This would be a real chance to leave first traces from UK to SA!
