Sur les bandes CW/digimode, tranquille, en AM comme grand papa, à comparer des appareils du commerce. 6 kHz étalant à 9 ? WTF ! c'est Milano, bébé !

My last two #hamradio QSOs yesterday were in FT8, so here’s a small picture of my digimode setup. The DIY digimode adapter sends the TX audio to the Xiegu G90’s ACC port, but it receives the RX audio from the G90’s headphone jack instead (from ACC does not work). #Amateurfunk

En découvrant le cluster de F1LED je viens de prendre connaissance qu4il existe maintenant un nouveau mode , le FT 2 ... Le FT2 est un nouveau mode numérique expérimental pour radioamateurs (apparu début 2026) (source Gemini) #ft2 #digimode #hamradio

🚨 ChronoGPS が海外ソフトウェアに統合されました！ イタリアのアマチュア無線家 IU8LMC (Martino) 氏が開発する FT2専用デジタルモードソフト「Decodium v3.0 FT2 Raptor」の 最新ビルドに、ChronoGPS v2.4.6 が統合されました。 しかも作者名 "by Yoshiharu Tsukuura, JP1LRT" と GitHubリンクまで About ダイアログに掲載していただいています。 📸 スクリーンショットを見ると… ・Decodium の Time Synchronization パネルに 　ChronoGPS v2.4.6 がそのまま組み込まれ ・NTP Status: Synced / Offset: 0ms という状態で ・FT2運用中のリアルタイム時刻同期を担っています Decodium はただのWSJT-X派生ではありません。 ・FT2モード専用に特化 ・デコード感度を 10〜25%向上させる独自パラメータ ・25以上のNTPサーバー対応 ・サウンドカードドリフトのPPMリアルタイム補正 ・DTフィードバックループ という本格派ツールです。 その時刻同期コアとして ChronoGPS が選ばれました。 事前に連絡はありませんでした。 オープンソース（GPL v3）の世界で こういう形で認められるのは、開発者として とても嬉しい驚きです。 IU8LMC氏、ありがとうございます！ 向こうから連絡が来るのを楽しみに待っています 😄 🔗 Decodium v3.0 FT2 Raptor: github.com/iu8lmc/Decodium-3… 🔗 ChronoGPS v2.4.6: github.com/jp1lrt/ChronoGPS/… #ChronoGPS #FT2 #FT8 #HamRadio #アマチュア無線 #DigiMode #OpenSource #WSJT #Decodium #JP1LRT

Introducing "ChronoGPS" - RFC 5905 Compliant Time Sync Tool Optimized for FT8/FT4/FT2 and Other Synchronized Digital Modes In digital mode operation such as FT8, FT4, and FT2, the accuracy of your PC clock directly impacts decode rates - it's absolutely critical. ChronoGPS goes beyond a simple time correction tool by strictly implementing RFC 5905 (NTPv4) internally, achieving a level of precision that sets it apart from existing sync tools. ■ Why does "RFC 5905" matter? Many lightweight time sync tools use "SNTP (Simple NTP)", which simply overwrites the PC clock with the time received from a server. However, internet communication always involves "path jitter" and "round-trip delay", which can introduce errors ranging from a few milliseconds to several hundred milliseconds. ChronoGPS, compliant with RFC 5905, performs the following advanced processing in the background: - Statistical Error Elimination: Measures the round-trip time of communication packets in milliseconds. Statistical filtering removes network-induced noise to derive true standard time. - System Clock Protection: Maintains consistency with the OS system clock while applying optimal corrections based on the RFC algorithm. ■ A "Head Start" for Future GNSS Operation Even if you currently operate primarily in an internet-connected environment, ChronoGPS truly shines if you ever consider portable or offline operation for FT8/FT4/FT2. When you add a commercially available GNSS (GPS/QZSS/etc.) receiver, ChronoGPS operates with it as a Stratum 1 time source at maximum precision. - Simply connect and configure your receiver to achieve high-precision timekeeping equivalent to - or better than - internet sync, even in mountainous areas or remote islands without network access. - Multi-GNSS Support: Not just GPS - fully utilizes multiple satellite constellations including Japan's "Michibiki (QZSS)", GLONASS, Galileo, and BeiDou for stable time acquisition. Start by experiencing its stability with everyday internet sync. Then, when you pick up a GNSS receiver, this software seamlessly evolves into a full-featured time sync tool ready for serious FT8/FT4/FT2 field operation. ▼ Project Details & Download (GitHub) github.com/jp1lrt/ChronoGPS/… #JTDX #ChronoGPS #FT8 #FT4 #HamRadio #AmateurRadio #DigiMode #WSJT #TimSync #NTP #RFC5905 #GNSS #GPS #QZSS #Michibiki #OpenSource #WindowsSoftware #DigitalModes #WeakSignal #WSJTX #HamRadioSoftware

We kunnen er niet omheen: er is weer een nieuwe veelbelovende digitale mode beschikbaar. En dat is FT2. Men schrijft over FT2: “waarschijnlijk de snelste digimode ooit ontwikkeld“. Lees er meer over op veron.nl/nieuws/ft2-de-nieuw… #RadioIsMagie #BeleefHetMetDeVERON #FT2

IO-86 next week schedule. I hope VR Digimode can be used for SSDV experiment again :) Also there's LABRE 92nd Aniversary on VR FM on 2nd February! @PU4ELT

SSDV is getting popular in 2026 🎉 SilverSat: Experimenting using IL2P and tweet from space @SilverSatorg IO-86: Started SSDV Digimode experiment using the FM repeater, first tested about two weeks ago Upcoming HADES-SA also do have on board SSDV transmitter

The likelihood is that those who operate FT8 (or whatever digimode) do also operate voice as well, so the only reason I think many older amateurs take the hump at FT8 is because they don't like innovation, but amateur radio is about innovation as well as speaking to others on air

Today's IO-86 Digimode Experiment on 02-08-2025 is agreed to be FT4 (over the FM transponder). Please don't transmit voice, FT4 only. Thank you!

Thanks for all the digimode contacts. Because of the FT8 character limitation please double check grid info here: qo100dx.club/news/634 All logs will be uploaded to QO-100 DX Club and LOTW within a few days of my return, as usual. 73 72 SM/F5VMJ #qo100 #hamradio #AmateurRadio

My first QSO via FT4 on IO-86 Digimode Experiment schedule 🥳. Somewhat tricky as you have to alternate with someone else as it's on FM. (Yes this is actually my first QSO via FT4/8, I never had success on HF before 😅)

Finally I can deploy the SatNogs rotator at my QTH (on a temporary location under the roof). First test was FT4 digimode experiment on IO-86. I can get through but can't decode it until the very last moment where I switch the receiver from RTL-SDR to an HT. Until next time!

So I tried something fun this weekend at the restaurant where I work. Throughout my whole shift, I wrote Digimon in Digimode/Digicode in the in an empty space of the brown paper bags we put the food in, hoping to see if any customer would notice the "unique" message.

blog.ok2awo.com/posts/freeda… Some thoughts around a relatively new HAM radio digimode. Also yeah, I finally made a blog.. wow me

Spontaneous activation of #POTA on the night shift. It was cold and wet, so I was in the car, this time only in digital mode. #hamradio #digimode
