Thread-topic: LF: 472 kHz distance records

​​Hello Stefan,


the idea is to list the best DX for the different modes (CW, QRSS/DFCW, digi), worldwide and for each continent. Similar to what exists for VHF and UHF bands (eg https://pk-ukf.org.pl/dxrec.html​).

Instead of just the best DX I can eventually list a top 3 or top 5.

It's up to what the 472 kHz community wants.


About WSPR: my first thought was to cinsider these as SWL reports (honoring the RX station), but maybe I should add the best TX station as well (for the continental records).

For FR5DX I already have a WSPR copy of G3KEV at 9915km, that is probably the WSPR RX record for Africa and maybe the TX record for Europe (although it might be possible that EU stations were copied in NA at distances > 10000km).


The KB5NDJ website is a great source of information, but unfortunately I don't have enough tiime to dig for record there.

Hello Rik,

What distances are of interest? > 5000 km for example?

My best results so far are:

Timestamp Call MHz SNR Drift Grid Pwr Reporter RGrid km az
 2016-03-01 05:50   DK7FC   0.475684   -18   -1   JN49ik   1   ZF1EJ   EK99ig   8393   283 

and FR5ZX in 9095 km, see http://njdtechnologies.net/wp-content/uploads/2015/10/DK7FC-FR5ZX-103115d.jpg
Fortunately captured by John on this site: http://njdtechnologies.net/noisy-conditions-in-na-have-impact-wh2xcr-has-another-good-session-dk7fc-fr5zx-lots-of-activity/

Best QRB for me in CW is < 2000 km, i don't know more details in the moment...

Dear all,


On Roger's (VK4YB) suggestion I added a distance record list at the 472kHz.org website, see http://www.472khz.org/pages/on-the-air/distance-records.php.

The list is as wel for world wide records as far continental records.

At this moment the list is only sparsely populated, I am awaiting your claims !!!
