IARU Region 1 VHF Contest 2020

Compte rendu du contest IARU R1 VHF des 5 et 6 septembre 2020. Je n’ai été actif que très partiellement, à savoir durant seulement 3 heures 30 sur les 24 que compte le contest. Je me suis attaché exclusivement à chercher les DX’s (mode “S&P”). La propagation était très “standard”, voire bonne vers le sud-ouest.
Station utilisée : 2×9 él. DK7ZB et 1,2kW

Subregional VHF Contest July/Juillet 2020

Compte rendu du contest subregional VHF des 4 et 5 juillet 2020. Je n’ai été actif que partiellement, à savoir durant 11 heures sur les 24 que compte le contest. Je me suis attaché exclusivement à chercher les DX’s (mode “S&P”). La propagation était très moyenne et les signaux relativement faibles. Assez peu de stations F actives.

Marconi Memorial VHF CW Contest 2019

Compte rendu du contest MMC VHF des 2 et 3 novembre 2019 ; il s’agit du seul contest VHF dédié uniquement à la télégraphie (CW), et un de mes préférés. Je n’ai été actif que partiellement, à savoir durant 11 heures sur les 24 que compte le contest. En raison du vent, j’avais descendu mon pylône en position “basse”, d’autant que je ne m’attendais pas à une très bonne propagation (mauvaise météo). Toutefois, à ma grande surprise, plusieurs stations italiennes et OM3KII ont été contactés (assez facilement) dans ces conditions, sachant en plus que vers l’est les antennes sont obstruées en position basse. Durant la nuit, le vent  a faibli, si bien que dimanche matin j’ai pu remonter le pylône et contacter plusieurs stations OK de plus, dont JO80 et JN89. A part vers l’est, peu d’actvité dans les autres directions, comme de plus en plus souvent malheureusement. J’ai beaucoup apprécié ce contest, c’est toujours un grand plaisir de pratiquer la télégraphie. Comme quoi, on peut aimer les modes numériques (entre autres le FT8) tout en restant un fervant amateur de télégraphie, les deux ne sont pas incompatibles, tout est une question de tolérance…

Activity report of the MMC VHF contest of November 2nd and 3rd, 2019 ; it is the only VHF contest exclusively dedicated to telegraphy (CW), and one of my preferred ones. I have been partly active, during 11 hours amongst the 24 the contests lasts. Due to the wind, I had lowered my tower in “low” position, even more I didn’t expect a very good propagation (bad weather). However, to my surprise, several Italian stations and OM3KII have been worked (fairly easily) in these conditions, all the more that towards the East the antennas are obstructed in low position. During the night, the windspeed has decreased, so that I could raise the tower again on Sunday morning and work a few more OK’s, including JO80 and JN89. Apart from the East, low activity all around, as more and more often unfortunately. I very much liked this contest, it’s always a great pleasure to practice CW. One can like the digital modes (FT8 amongst others) while remaining a fervent amateur of telegraphy, both aren’t incompatible, it’s all a matter of tolerance…

IARU Region 1 VHF Contest 2019

Compte rendu du contest IARU VHF des 7 et 8 septembre 2019. J’ai été actif durant environ 14 heures sur les 24 que compte le contest. Je me suis attaché uniquement à chercher les DX’s, je n’ai quasiment jamais appelé CQ. Propagation pas terrible, les signaux étaient relativement faibles. J’ai eu le sentiment qu’il y avait moins de stations DL que d’habitude et vers la France, à nouveau une faible activité était à déplorer. Pourtant, même à presque 800 km, TM2D (JN03) arrivait souvent très fort. Sur KST, il semble que plusieurs stations demandent des skeds “en masse”, sans visiblement tourner leur antennes ou avoir un groupement dans la direction concernée… Quand je compare ce contest IARU 2019 avec celui de 2018, les conditions étaient nettement moins bonnes cette année.

Activity report of the IARU VHF contest of September 7th and 8th, 2019. I have been active during around 14 hours amongst the 24 the contests lasts. I only focused on hunting DX’s, I have almost never called CQ. Poor propagation, signals were relatively weak. I have had the feeling that there were less DL stations than usual and towards France, again a low activity was to deplore. However, even at almost 800 km distance, TM2D (JN03) was often coming through quite strong. On KST it seems several stations are requesting “mass” skeds, without apparently turning their antennas or having an antenna group in the concerned direction… When I compare this IARU 2019 contest with the one of 2018, conditions were clearly less good this year.

CU8 <> ON Tropo path on 144 MHz

On Tuesday September 3rd, 2019, I have been lucky enough to work CT8/W6PQL on 144 MHz in FT8 (QRB 2875 km) in Tropo. James is active in August/September 2019 from his holiday house on Pico Island (HM58RN) in the Azores archipelago.

backyard2From HM58, James was so far active mostly in EME with 2x10el Xpol and 1kW. I worked James already last year and one week ago in EME. I wasn’t aware James was also active in Tropo. So, when I saw the spot of F8DBF (IN78) highlighting a QSO with CT8/W6PQL, I turned my antennas towards Azores, tuned my transceiver on 144.174 MHz and started calling “CQ DX ON4KHG JO10” in FT8, without too much hope…

After a few sequences, and despite some non-DX stations were calling me (a real problem in FT8 sometimes…), I couldn’t believe my eyes, CT8/W6PQL was calling me ! Actually, “W6PQL” was calling. Indeed, James is used to EME JT65 operation and in JT65, a callsign like “CT8/W6PQL” isn’t supported (I think). In FT8, “CT8/W6PQL” is well supported but then the QRA locator isn’t sent (exchanging the QRA locator isn’t mandatory for a valid QSO according to the IARU however). Since the callsign was truncated, a few ones (against digital modes) will probably claim the QSO wasn’t valid (or just not valid at all because being in FT8 ;o). Well, it is just a matter of software “misuse” (if the callsign of James would have been CT8XYZ, there wouldn’t be any discussion) and most important, the propagation path was open, allowing distant stations to exchange a minimum set of information for a valid QSO. So, from my own perspective there is no question the QSO is complete or not,… it is ! After our QSO, I saw James calling again, as can be seen on the screenshot below seen from my station :

W6PQL

James sent me the screenshot of our QSO from his station :

W6PQL - 2

The strongest James received me was -12dB (in a 2500 Hz BW) and me -15dB from him. This shouldn’t have been strong enough to sustain a CW QSO. This is the second time I work Azores on 144 MHz in Tropo.

The first time was on May 17th, 2011, when I worked Fred, CU8AO (HM49KL) in SSB over a 2991 km path. The CU8DUB beacon was then audible here quite strong for hours :

Frank, PA4EME, heard CU8DUB too over 3150 km. One year before, on September 14th, 2010, the same beacon was heard 529 in Belgium by Michel, ON4POO, and CU8AO made several QSO’s with UK and French stations on the Atlantic coast, but none with Belgium.

For my 2 QSO’s with Azores, the path wasn’t totally over the sea. To the QTF of Azores, I’m living 180 km inland. For the QSO with CT8/W6PQL, the path was even more further interrupted by lands at two occasions, the French “presqu’île du Cotentin” (Normandy) and at James’ side the Sao Jorge Island.

Right after the QSO with James, CT8/W6PQL, I listened to the French beacon F5ZSF in Brittany (IN88) on 144.409. It wasn’t stronger that usual, just about normal (539 or so).

The F5LEN tropo forecast indicated a strong tropo enhancement between Azores and Brittany, but not extending any further. This forecast turned out to be quite reliable however !

So, beside the now famous UK/EI <> EA8/D4 path, the CU8 <> F/UK/ON path deserves attention though the CU8DUB beacon isn’t active anymore unfortunately.
