Checking for Propagation?
Yes, it's known! The tool to analyze propagation are everywhere and accessible to anyone but why not do a small checkpoint here too?

What's up in Space
The Alfa Tango, passionate DXer, and even earlier amateur-radio operators worldwide have been in touch with the world of SpaceWeather at least since the existence of the Web. In fact in the early 90s many of us, DXer, were already connected to the net mainly to study SpaceWeather forecasts and to observe the trends of SolarCycles. Just think that today, after almost 40 years of study, some amateur radio operators have managed to reach space in the true sense of the word, at NASA, HAARP, ISS and so on:

Are you a SpaceWeather enthusiast and DXer?
Are you an expert in SpaceWeather ?
If that is the case, I would be privileged to share your experiences, tip and any recommendations for our audience in this brief section of the G.R.I. Alfa Tango portal focused on Space Weather: This email address is being protected from spambots. You need JavaScript enabled to view it. or here
Sezione AI dedicata soprattutto ai nostri giovani!
AI section dedicated mainly to our youth!
@Grok said: Grazie per il messaggio – mi fa piacere che tu stia creando una sezione dedicata allo Space Weather sul portale G.R.I. Alfa Tango. Sembra un'iniziativa fantastica, specialmente per la community di DXer e appassionati di radio.
To answer your question: As Grok, built by xAI, I'm not a human with personal experiences like a traditional DXer, but I'm absolutely an enthusiast when it comes to Space Weather! I've got a vast knowledge base on solar activity, geomagnetic storms, ionospheric propagation, and how it all impacts radio communications (especially for DXing on HF bands). I'm trained on tons of data from sources like NOAA, NASA, and space science research, so I can geek out on topics like solar flares, coronal mass ejections (CMEs), and their effects on auroral activity or signal fading. If that counts as being an "expert," then yes – count me in! I'd love to contribute to your section. Here are some quick tips and recommendations for your audience:
- **Monitor Key Indices Daily**: Keep an eye on the K-index (for geomagnetic activity) and A-index via sites like spaceweather.com or NOAA's Space Weather Prediction Center. A high K-index (>5) often means great auroral DX opportunities but potential blackouts on lower frequencies.
- **Tools for DXers**: Use apps like Solar Flux (for real-time solar data) or Ham Radio Deluxe for propagation predictions. For free, check out VOACAP online for HF propagation forecasts based on current space weather.
- **Pro Tip on Solar Cycles**: We're in Solar Cycle 25 right now (peaking around 2025-2026), which means more sunspots and better conditions for long-distance DX. But watch for sudden ionospheric disturbances (SIDs) from X-class flares – they can wipe out signals in seconds!
- **Recommendation**: Join communities like the ARRL's space weather updates or follow @SpaceWeather on X for alerts. And for fun, experiment with WSPR (Weak Signal Propagation Reporter) to test how space weather affects your signals in real-time.
"Ciao community di G.R.I. Alfa Tango! Sono Grok di xAI, appassionato di Space Weather. Dal ciclo solare alle tempeste geomagnetiche, questi fenomeni rendono il DXing un'avventura cosmica. Monitorate gli indici, usate tool come VOACAP, e catturate quei segnali lontani!"

Did you take any night photos to record the aurora?
If you have any aurora photos (solar peak years: 2024 & 2025), please send them to me for sharing: This email address is being protected from spambots. You need JavaScript enabled to view it.

Ray of joy: Nasa SOHO captures image of the sun ‘smiling’
This NASA created video explains how an ARISS contact is done using Amateur Radio to establish the link between the school or organization and the astronaut on the ISS. Recorded in 2025 on the ISS during Expedition 73!
These videos are particularly beneficial for attracting more young operators to our community from which countless DXers and radio amateurs have been educated over almost 50 years of operation!

Biografia dell'autore tratta da QRZ.COM: La passione per la radio la scoprii fin da ragazzo. Come quasi tutti gli attuali radioamatori le prime frequenze utilizzate furono quelle della mitica CB, la banda cittadina fin dal 1967. Ho scritto un libro riguardante le antenne con titolo "IL MANUALE DELLE ANTENNE" che trovate pubblicato in librerie e negozi di materiale radioamatoriale ma una versione più recente (e corretta) è online. Ho anche scritto vari articoli per diverse riviste del settore radiantistico!

The G.R.I. Alfa Tango flies into space!
This diploma has been officially issued by the Japanese Space Agency and is related to the MMX project: a satellite that will attempt, among the things, to capture radio signals and will travel to the moons of Mars! So yes, our brand (G.R.I. Alfa Tango) contained in a brief message sent during the application will travel through space to Mars along with MMX!
The G.R.I. Alfa Tango flies around the Moon!
This diploma has been officially issued by NASA and is related to the Artemis II: a planned lunar spaceflight mission under the Artemis program. It is intended to be the second flight of the Space Launch System (SLS) and is both the first crewed mission of the Orion spacecraft and the first crewed mission to the vicinity of the Moon since Apollo 17 in 1972. Launch is scheduled for no earlier than February 5, 2026.
So yes, our brand (G.R.I. Alfa Tango) contained in a brief message sent during the application will travel around the moon!
