Subregional VHF Contest March/Mars 2019

Compte rendu du contest subregional VHF des 2 et 3 mars 2019. Je n’ai été actif que très partiellement, à savoir durant seulement 7 heures sur les 24 que compte le contest. Je me suis attaché principalement à chercher les DX’s (mode “S&P”) avec un certain succès, malgré une propagation vraiment pas terrible (tout comme le WX du moment, pluvieux et venteux), surtout le dimanche. Les signaux étaient relativement faibles, entachés d’un QSB lent et profond. Plusieurs QSO’s DX ont ainsi probablement été complétés à l’aide d’airplane-scatter. Dimanche en fin de matinée, je me suis fait plaisir avec une session d’appels (mode “Run”). 40 QSO’s furent logués en 30 minutes ; ça répondait sans cesse, parfois plusieurs stations en même temps, quel plaisir… Moins de stations OK que d’habitude, pas d’OM cette fois et rien en direction du sud de la France ou EA. OK1KTW (JN89IW) ne m’a jamais entendu et je n’ai contacté personne en JO70 ni JO80. Par contre, 5 stations italiennes contactées, dont IQ2CJ qui était un “réel” 59.
Station utilisée : 2×9 él. DK7ZB et 1,2kW

Activity report of the subregional VHF contest of March 2nd and 3rd, 2019. I have been very partly active, during only 7 hours amongst the 24 the contests lasts. I mainly focused on hunting DX’s (mode “S&P”) with some success, despite a poor propagation (like the windy and rainy WX), mainly on Sunday. Signals were relatively weak, tainted with slow and deep QSB. Several DX QSO’s have then probably been completed thanks to airplane-scatter. Sunday in the late morning, I had fun with a calling session (“Run” mode). 40 QSO’s were logged within 30 minutes. My CQ’s were answered constantly, sometimes several stations at the same time, what a pleasure… Less OK stations than usual, no OM this time and nothing in direction of the South of France nor EA. OK1KTW (JN89IW) never heard me and I didn’t contact anyone from JO70 nor JO80. On the other hand, 5 Italian stations were contacted, including IQ2CJ who was a “real” 59.

Subregional VHF March 2019


144 MHz tropo opening of end of 2018 and beginning of 2019

Below the map of the QSO’s I have been lucky to work on 144 MHz during the period December 25th, 2018 to January 6th, 2019. The conditions lasted for days, thanks to a steady high pressure system over Western Europe. Stations on the North coast of Spain were hearing the OY beacon but unfortunately there was no activity from the Faroes Islands. In JO10XO, I was out of the North-South duct but I could benefit however from excellent conditions from South-West to North-West. UT1FG/MM was worked while in IN66, JO12, JO25 and JO36 (3 new #). I missed IN67 as I was out for the New Years eve. The map depicts SSB, CW and FT8 QSO’s.

UT1FG/MM – Yuri

2019_01_06_21_02_48_https_s3.amazonaws.com_files.qrz.com_g_ut1fg_IMG_1476453682005_V.jpg_InterneYuri, UT1FG is often active as UT1FG/MM on 144 MHz. He operates from the ship “Goldeneye”, a bulk carrier sailing under Cyprus flag. On the page of Yuri, one can see the ship.

The Goldeneye has left San Lorenzo in Argentina on 8/12/2018 with Riga (Latvia) as destination. Yuri has been active during the travel from several “wet” squares on 144 MHz. I have been lucky enough to work him when he was in IN66, JO12, JO25 and JO36. Three of them were new #. The mode Yuri used was FT8. On likes FT8 or not is another discussion ! I wanted to know the full (6 digits) loactors where Yuri was when I worked him. Provided the latitude / longitude position of the ship can be received by costal stations receiving AIS (Automatic Identification System) frames emitted by the boats (161.975 and 162.025 MHz), it is quite easy to derive the QRA locator. I describe here the way I proceeded.

I go the either or One has sometimes a more recent position that the other or vice-versa. The AIS frames contain the latitude and longitude of the ship ; these are broadcasted on the above mentioned frequencies. Once received by a costal AIS station that reports the received postions of the ships to vesselfinder or marinetraffic over the internet, one can retrieve the latitude and longitude of the ship. Below is an example with marinetraffic. Look for “Goldeneye” on the top right when accessing the website and you will get this if you select the Goldeneye from Cypris, i.e. [CY] (click on picture to enlarge) :


From there, you can see the latest postion of the ship, its past track and even its forecasted route.


On the top right of the picture above, one can see the latitude and longitude of the ship, expressed both in DD and DMS. Feeding an online QRA locator calculator2019_01_03_09_39_15_QTH_locator_calculator (e.g. with these data and one get the QRA locator of the ship. In the present case, it was in JO24KH. Again, this is possible provided the ship is under the coverage of a costal AIS receiving station. Otherwise, satellite positioning of the ships is also possible but this is a paid service.

End of January 2019, on his way from Estonia to Brazil, Yuri has activated again wet squares on 144 MHz. Yuri is transmitting with 20W into a 5 elements antenna. Hereby a screenshot from JO35 :

Many thanks to Yuri for activating all these wet squares !


Marconi Memorial VHF CW Contest 2018

Compte rendu du contest MMC VHF des 3 et 4 novembre 2018 ; il s’agit du seul contest VHF dédié uniquement à la télégraphie (CW). Je n’ai été actif que très partiellement, à savoir durant seulement 8 heures sur les 24 que compte le contest. Propagation relativement normale, qui a néanmoins réservé quelques belles surprises. En effet, 3 stations slovaques, ainsi que 6 stations italiennes ont été contactées, toutes relativement facilement. L’essentiel de l’activité restante en CW sur 144 MHz se trouve à l’est (ça n’est pas nouveau). Au Royaume-Uni et en Belgique, il y avait peu de monde, et encore moins en France et aux Pays-Bas, qui deviennent des “déserts télégraphiques” (hormis quelques stations, toujours les mêmes). J’ai vraiment beaucoup apprécié ce contest, c’est toujours un grand plaisir de pratiquer la télégraphie, même si je la trouve particulièrement archaïque et évidemment sans avenir (rares sont ceux qui en doutent encore…). Comme quoi, on peut aimer les modes numériques (comme le FT8) tout en restant un fervant amateur de télégraphie ; les deux ne sont pas incompatibles.
Station utilisée : 2×9 él. DK7ZB et 1,2kW

Activity report of the MMC VHF contest of November 3rd and 4th, 2018 ; it is the only VHF contest exclusively dedicated to telegraphy (CW). I have been very partly active, during only 8 hours amongst the 24 the contests lasts. Relatively normal propagation, with some nice surprises though. Indeed, 3 Slovak, as well as 6 Italian stations have been worked, all fairly easily. Most of the remaining CW activity on 144 MHz takes place to the East (this is not new). In the UK and Belgium, very few people, and even less in France and The Netherlands, these become “telegraphic deserts” (except few stations, always the same). I very much liked this contest, it’s always a great pleasure to practice CW, even if I find it particularly archaic and obviously future less (who still doubts it…). One can like the digital modes (like FT8) while remaining a fervent amateur of telegraphy ; both aren’t incompatible.

IARU Region 1 VHF Contest 2018

Compte rendu du contest IARU VHF des 1er et 2 septembre 2018. J’ai été actif durant seulement 7h30 sur les 24 que compte le contest. Bonne propagation dans toutes les directions, sauf peut-être vers le nord. Toutefois pas de signaux super QRO, mais la possibilité de faire des QSO plus facilement que d’habitude, notamment OM3KII contacté en SSB alors que les fois précédentes c’était en CW. Etant donné mon temps d’activité limité, je me suis attaché à chercher les DX plutôt qu’appeler CQ ; je n’ai fait que quelques rares sessions d’appel, ce qui explique le nombre limité de QSO’s et la moyenne km/QSO elevée. Un très bon contest donc que celui de cette année, avec 20 QSO’s à plus de 800 km. L’activité était également assez soutenue. 7 stations EA contactées, 6 stations I, 3 stations GM, 2 stations SP,…

Activity report of the IARU VHF contest of September 1st and 2nd, 2018. I have been active during only 7h30 amongst the 24 the contest lasts. Good propagation all around, except perhaps to the North. No super QRO signals though, but the possibility to make QSO’s easier than usual, in particular OM3KII worked in SSB whereas it has always been in CW so far. Given my limited activity time, I have been focussing on searching for DX’s instead of calling CQ ; I have just made some rare calling sessions, which explains the limited amount of QSO’s and the high km/QSO average. So, a very good contest the one of this year, with 20 QSO’s beyond 800 km. The activity was fairly strong too. 7 EA stations worked, 6 I stations, 3 GM stations, 2 SP stations,…

VHF IARU Region 1 September 2018

Ecoutez EA3LA (JN12IK) dans la petite vidéo Youtube ci-dessous (désolé, le son est un peu faible). Le FT-857 indique “28.210” mais il est suivi d’un transverter 28>144 MHz, la fréquence réelle est donc “144.210”.

Listen to EA3LA (JN12IK) in the short Youtube video below (sorry, the sound is a bit weak). The FT-857 indicates “28.210” but it is followed by a 28>144 MHz transverter, the real frequency is then “144.210”.
