Anatomy of a #Solar #Storm - take advantage of enhanced #hamradio #HFPropagation during the positive phase of the Storm #spacewx #spaceweather qrparci.org/resource/FDI...
After more than 5000 lines of code, my AI data-driven HF propagation model is starting to make sense
I created an interactive Grafana dashboard showing the (in)operational Status of worldwide Ionosondes. Updated twice a day grafana.gafner.net/d/bf1mba4zm0... #hamradio #spacewx #hfpropagation
Before a #CME hits Earth's magnetic field, high-speed solar wind streams and energetic particles can already reach Earth. These interact with the ionosphere, particularly the F2 layer. This interaction can temporarily increase ionization in the upper ionosphere #hamradio #spacewx
Effect of Solar radiation on #HFPpropagation #spacewx

1–8 Å = “bad news” for HF (absorption, blackouts)
100–1000 Å = “good news” for HF (increased ionization, higher MUF)

Data on my website grafana.gafner.net/goto/7LIFgS6... #hamradio
As a rule of thumb, when the 10.7 cm solar flux is above 150 and the Kp index remains below 4, you can expect great #DX condx on the higher HF bands like 10 m, 12 m, 15 m, and 17m. Check the current #SpaceWX and key #HFPropagation indicators at my website grafana.gafner.net/d/kAZyp6bMz/...
Last week, 10m DX was picking up 🚀 Expecting to see even better condx in the coming weeks
The forecast for the DX performance of the 10 m band is far behind that of September 2024
Combined chart showing the average annual Kp and Ap indices from 2020 to 2025 #sc25
A high Solar Flux Index generally improves HF propagation by raising the MUF and opening up the higher bands. SFI is currently at 226, and DX on 10m is picking up is.gd/WoY6pk

SSB radio enables long-distance communication without satellites or infrastructure, using HF bands to bounce signals off the ionosphere. A lifeline for sailors beyond VHF & cellular range

Know-how: The Single Sideband Radio - SAIL Magazine
Is single sideband radio still relevant in today’s Starlink world?

WSPR is a great tool to:
- Optimize your RX/TX
- Assess your HF Propagation
- Compare performance with other stations
- Compare performance of Antennas
- Compare RX performance of Radios/SDRs

Some of the tools I use on a daily basis

The DX peak for the high ham radio bands was likely in 2024. Autumn MUF will show #sc25 #hamradio #spacewx
Look at the progress of their projects.
They are moving to slow. Too much overhead
Yes we will start with one transmitter and one rx
I was reaching out to ARDC to check if this project would qualify for a Grant. Unfortunately, individuals don't get grants without fiscal sponsors. Furthermore, ARDC wants to have evidence of demand from potential future users. Too many roadblocks...
This is bloody brilliant. I've spent months optimizing my RX and it's finally a top-notch receiving station. Over 1000 WSPR reporters in the last 24 hours, which I rank 12th for unique spots and 33rd for distance. Not bad at all considering my suburban QTH, far from an RFI quiet location
Thanks to WSPR, we know the rf power and thanks to the intl. WSPR Beacon Project, we also know the Antenna gain. We can derive a model from that. Step by step
The prediction quality is expected to be as ~good as that of terrestrial weather... Far from an exact science.
FT8 is not a good fit, no pwr information. WSPR contains locators and has a central DB with an API currently holding more than 9 billion historic spots. Thank you
The WSPR DB holds more than 9 billion spots, worldwide coverage, that‘s a good data source to start with
I am taking a break from social media. I need a digital detox. I will continue to experiment and chase DX. 73 #hamradio
