NDB DX'ING BLOG 190-1750 KHz

The band was quiet this morning with some conditions to Canada and Atlantic. Nice to hear again 318-MAD and 250-YMH, not very often heard here:

The 26th October 2007 at 05.51 UTC, I was in my shack, huting the DX. On 280 KHz, I could hear a carrier. 280-QX was familiar Canadian NDB at home. I have decided to listen to the 1020 Hz offset. I could not believe it : 280-IPA Easter Island at 13.615 Kms from my QTH.





The signal was very strong!

Hope to catch it the next DX season !

Last night, I put on 490 Khz the receiver to see the condition on this navtex frequency. I am pleased to catch the new Islandic station Grindavik on his new slot (K):

It isn't the best season to chase the DX on the low band but monitoring the Navtex frequencies gives an good idea about the propagation. Heard all european station and some Canadian stations also:

Since few days, a new italian NDB is active:

418-SVC with an 1020 Hz offset
Location: Aosta, ITA
QTH: JN35UR

Thanks Aldo for the tip,

Après le NAVTEX, il y a aussi les stations DGPS qu'il est possible de recevoir. Elles remplacent toutes les balises maritimes que l'on pouvait entendre auparavant. Depuis maintenant quelques années, nous pouvons entendre du bruit entre 283.5 KHz et 325 KHz tous les 500 KHz.

Là aussi le DX est possible en utilisant les variations de propagation, la directivité des antennes de réception et la saison dans l'année. Par exemple, sur 307.5 KHz, la station dominante est la station anglaise de Ste Catherine'Point à 481 Km de mon QTH et en choisissant une antenne orientée à l'Est, je reçois dans d'excellentes conditions la station turque de Kumkale à 2215 km:

Station ID 547;[Kumkale TUR KM39CX 307,5 khz TX ID #374];msg typ 09;tim 10.20;seq 3;len 0;health 6;[200bps];07-03-13 19:10:19

Mon meilleur DX est la station Isabella située à Puerto Rico dans les Caraïbes, soit une distance de 6807 km.

Régulièrement, je mets le récepteur sur les fréquences NAVTEX 490 KHz / 518 KHz et parfois 4209.5 KHz et je décode les signaux des stations côtières qui émettent des bulletins à destination des bateaux. Sur 518 KHz, tous les messages sont en anglais quelque soit la station alors que sur 490 KHz c'est la langue du pays qui transmet qui sera utilisée.

Voici quelques extraits des stations lointaines reçues dans la Vienne:

Last winter, few of us could hear some NDB from Brazil. I was one of them. The most distant from my place was 260-CZS

at 9352 km in Cruzeiro do Sul (FI32OJ). I was also surprised to catch DX between 210 and 270 KHz. In Europe we have a lot of broadcast and it isn't easy to find weak signal like 215-TRS, 220-TUI and 240-TIR.

On 410 KHz, I have a strong spanish NDB: C. On the MP3 file we will hear also PEL Ponta Pelada / Manaus:



The following NDB were heard also from my QTH:

260-FLZ
275-MSS
280-SLI
350-STM
360-JAC
365-CVL
520-BHZ
and the most easiest from Europe 1700-CRJ with an offset of 780 Hz.

Try it and you will be fascinating by this DX signal like I was !

The band was a little noisy this morning due to the static. The conditions were good enough to hear some DX. All time are UTC and country code comes from NDB list.

Ce blog va retracer principalement mon activité d'écoute des balises aéronautiques entre 190 KHz et 1750 Khz avec quelques débordements sur la réception des stations DGPS (280-325 KHz) et NAVTEX (490/518 KHz).

Certaines notes seront en anglais afin de rendre ce blog plus "ouverts" vers les autres écouteurs et de permettre des échanges internationaux.

Vous retrouverez également des notes sur les logiciels, le matériel et les antennes.

Longue vie à ce blog et à bientôt,
