Ham radio enthusiast since 1986. I knew short waves before the iron curtain came down. The shortest distance between two points depends on the propagation.

@f5len C’est ce que j’ai fait hier soir mais ce matin pour le log de F4WFI/P mais le RBN me voit toujours à Paris. Tu sais si cela prend un certain temps ?

Des experts de RBN dans la salle ?
J’ai une question pour vous : je n’arrive pas à changer mon QTH dans le RBN en changeant l’info sur ma page QRZ.
Est-ce que l’un de vous a déjà fait ?

@f5len @fnrasec @fr_emcom @Prefet57 @SecCivileFrance @Prefet67 Le Cinq-Sept est bien connu pour ses feux de forêt.
Après c'est très bien de faire des exercices de temps en temps. Il y en a probablement pas assez.
En ce qui concerne les BBQ ( et la radio ), tu es le bienvenu et tu conais l'adresse .

👊Forty Meters, Pencil Lead, and the Sound of Europe
These two W6SL logbook pages capture a tight operating slice from the 1999 ARRL CW DX Test, and the numbers tell a clean story: roughly 52 contacts, nearly 90 percent on 40 meters, and essentially 100 percent CW.
▶️This was not casual dial-spinning. Once the contest rhythm appears around 0559 UTC on February 20, the page becomes a steady stream of European callsigns: OK, DL, YU, S5, LZ, PA, DF, OM, LY, OH, LA, SP, and EA. The exchange pattern is unmistakable - 599 reports, power entries, and tight spacing between QSOs. W6SL was not just logging contacts. He was working a 40-meter DX pipeline.
▶️The strongest measured segment shows about 38 QSOs in 77 minutes, roughly 30 contacts per hour, with a sharper burst approaching 36 per hour. By modern computer-logged contest standards, that may not look explosive. But this was hand-copy CW, written in pencil, under real RF conditions. No software safety net. No automated rhythm section. Just ears, timing, judgment, and operating discipline.
▶️The page has a quiet kind of authority. It shows an operator who knew when the band was open, stayed with the path, and kept extracting value from it contact by contact. The checkmarks in the QSL columns add another layer: this was not only contest scoring. It was confirmation culture. Proof culture. The paper trail mattered.
🛑For The W6SL Memorial Logbook, this is exactly the kind of artifact that deserves preservation. The numbers reveal the performance. The handwriting reveals the human being. And somewhere between those 7 MHz entries, you can still hear forty meters doing what forty meters does best - carrying CW across the dark.

A cosmic memory! 🙌
The 66 ALMA antennas were assembled in Chile.
In the photo, two engineers are working on the dish of a European antenna for ALMA, installing the metal panels that make up the reflective surface.
The dish is 12 meters in diameter!📡

Ça faisait un bail ! #entendusur80m
" - les VNA je ne m'y connais pas trop.
- ah moi sans me vanter je suis un spécialiste. Ca n'a aucun secret pour moi. Les logs, le diagramme de Schmitt ..."
