Hello, everyone.

Have you managed to make contact with Franz Josef Land?

I hear there are some die-hard operators out there who have already bagged every single slot—FT8 on the 12–20m bands and CW on the 40–10m bands.

Our family is giving it our best shot, too, but we still haven't made contact on the 40m or 10m bands; it seems the timing just isn't working out for us.


Last night, I was aiming for a "New Band" contact with RI1FJL, but it didn't work out.

But then...

For some reason, there was an incredibly strong signal on 17m FT8.

Even with my modest setup (a humble long-wire antenna), 

I was seeing a +26 signal report!

It was the kind of signal strength you rarely even see from domestic JA stations.

It turned out to be P29YY (Papua New Guinea)!!

.....
Yes yes We had got him.

Driven by his one-of-a-kind solo spirit and dealing with severe baggage limits, he overcame every challenge. Through his clever and original station design (his specific antenna choice and setup), he is finally on the air from a lonely island in the South Sea! The secret to his powerful signal is entirely revealed in this blog. 

His sheer execution—setting up in record time right after arrival and achieving these results—deserves the highest respectice.

Be sure to read his blog and catch him on the air. 

You’ll definitely want to support him as he fights the good fight on that remote Pacific island.


彼にしかできない唯一無二(オンリーワン)の運用、そして厳しく制限された持ち込み荷物。そんな制約だらけの状況の中、彼は独自の運用手法(アンテナ形式の選択や設置方法の工夫)を駆使し、ついに南海の孤島から送信を開始しました。彼の発射する電波の強さ、その秘密はこのブログの中にすべて書かれています。特に、現地到着からわずかな時間で設営を完了し、これほどの成果を上げる彼の実行力は、まさに尊敬に値するものです。ぜひこのブログを読み、彼と交信してください。きっとあなたも、太平洋の孤島で奮闘する彼を応援したくなるはずです。

20260828 RI1FJL( FRANTZ JOSEF LAND ) on 12M CW


20260828 RI1FJL( FRANTZ JOSEF  LAND ) on 12M CW 




20280828 1154UTC 24892.7kHz CW RI1FJL

IC-7100M original wav file ( add fade in-out ) .*. not enough Gain



                                                                                                                                        DL Button

📡 Operating Setup
  • Transceiver: ICOM IC-7100M (Internal SD card recording, raw unprocessed audio)
  • Antenna: Long-wire (Approx. 20 meters long / 13 meters high at the apex)
  • Decoding Software: DeepCW (Introduction & Guide via Zenn) / Source Code & Documentation via GitHub
    Note: DeepCW is a next-generation, high-precision Morse code decoder powered by deep learning. It runs entirely in browsers or mobile devices for free.
🎧 Human Ears vs. AI "DeepCW"
The receiving audio at the time was highly challenging. For CW beginners, the noise was so overwhelming that it was nearly impossible to copy. Even for intermediate operators, while faint signals could be distinguished, listening to such a low S/N channel for an extended period would be quite exhausting.
Yet, look at the text output generated by DeepCW directly from the raw WAV file. The full picture of a fierce DX pileup is vividly brought to light from beneath the heavy noise floor.
📝 The Drama Captured in the Text
The decoded log clearly reveals the callsign of RI1FJL (Franz Josef Land), a highly rare DX station in the Arctic region, surrounded by a swarm of stations calling them, along with the "UP" code indicating split operation. Although there are minor character corruptions due to fading and noise, the AI perfectly adapted to the context, preserving the raw, authentic atmosphere of the airwaves.
🏆 A Successful Husband-and-Wife DX QSO: A Beginner's Brave Challenge!
Amidst this intense pileup, both myself (JJ5IZX) and my wife (JJ5IZY) successfully made contact with RI1FJL using our 20-meter long-wire antenna and the IC-7100M.
Actually, my wife (JJ5IZY) is a complete beginner when it comes to CW. Under the pressure of this extreme noise and the fierce global pileup, she was incredibly nervous and repeatedly made keying errors during her transmission. However, she refused to give up, keeping her hands on the paddle until her signal finally broke through to the polar station. It was an unforgettable, dramatic moment for both of us. The decoded text, which captures our callsigns stamped multiple times alongside some imperfect code fragments, stands as proud proof of her great fighting spirit.
Without relying on any high-end external audio interfaces or heavy PC-side filtering, the rig's raw recording alone provided sufficient dynamic range for both successful decoding and operation. This experiment has been deeply satisfying, brilliantly proving the excellent baseline performance of the IC-7100M, the incredible noise tolerance of DeepCW, and the hidden potential of a simple long-wire antenna.
🌟 Special Thanks to the DX Pedition Team
Finally, we would like to express our deepest gratitude and respect to the RI1FJL DX Pedition Team. Operating from the extremely harsh and freezing environment of the Arctic, their exceptional operating skills and endless patience allowed them to pluck our weak signals from far-away Japan—and even patiently copy the hesitant, flawed keying of a CW beginner—to complete the contacts. 
Thank you so much for the unforgettable QSOs! 73!



【実験・運用レポート】IC-7100Mの素の録音から、AIデコーダー「DeepCW」で北極圏の極地DXパイルアップを炙り出す!
今回は、ICOM IC-7100Mの本体録音機能(SDカード記録)をあえてそのまま使用し、フェードイン・アウト以外の音声加工を一切行わずにAI/ディープラーニングを活用したCW解読ソフト「DeepCW」に読み込ませる実験・運用を行いました。
検証時間は1200UTC(21:00 JST)。この時間帯の12mバンド(24MHz帯)は電離層のコンディションが急激に低下するため、S/N比が非常に悪く、15mバンドに比べると格段に厳しい悪条件となります。
📡 運用環境・システム
🎧 人間の「耳」とAI「DeepCW」の対比
この時の受信音は、CW交信の熟練者ならともかく、初心者の方にはノイズが勝ってしまい聞き取りがかなり難しいレベルでした。中級者であっても「なんとか判別はできるが、長時間聴き続けるのは苦痛を伴う」というほどの過酷なLow S/N環境です。
しかし、実際のWAVファイルからDeepCWが弾き出したテキスト(TXT)をご覧ください。激しいノイズの底から、リアルなパイルアップの全貌が克明に浮かび上がっています。
📝 解読テキストが証明するドラマ
テキスト内には、北極圏の超珍局であるRI1FJL(フランツ・ヨーゼフ諸島)のコールサインと、それに群がる世界中の局、世界的なスプリット運用を指示する "UP" の符号が鮮明に記録されています。ノイズによる一部の文字化けはあるものの、無線界のリアルな空気感を残しつつ、文脈を完璧に補正してデコードしています。
🏆 初心者の妻も大奮闘!夫婦で北極圏とのCW交信に成功
そしてこの過酷なパイルアップの中、私(JJ5IZX)と妻(JJ5IZY)の2局とも、この20mロングワイヤーアンテナとIC-7100Mの組み合わせで見事にRI1FJLとの交信(QSO)に成功いたしました!
実は、妻(JJ5IZY)はCWを始めたばかりの初心者です。この極限のノイズと激しいパイルアップのプレッシャーの中、緊張のあまり途中で何度も何度もミスキーイングを繰り返してしまいました。 それでも諦めずにパドルを叩き続け、ついにそのコールサインが極地のオペレーターへ届いた瞬間は、我が家にとって忘れられない感動のドラマとなりました。テキスト内に不完全な符号の揺らぎを含みながらも、私たちのコールサインが何度も刻まれているのがその大健闘の証拠です。
外部の高級オーディオインターフェースやPC側でのフィルターに一切頼らず、リグの素の録音データだけでこれだけの解読・運用ができる。IC-7100Mの基本性能の高さと、DeepCWの驚異的なノイズ耐性、そしてシンプルなロングワイヤーのポテンシャルを証明できた、大満足の検証結果となりました。
🌟 DX Pedition チームへの謝辞
最後に、極寒の北極圏という過酷な環境から、私たちのような遠く離れた日本の小出力・シンプルアンテナの信号、そして初心者のたどたどしいキーイングをも辛抱強く拾い上げ、見事に交信を成立させてくれた RI1FJL DX Pedition チームの素晴らしいオペレーティング技術と情熱に、心からの深い感謝と敬意を表します。 最高のQSOをありがとうございました!73!
