Expect quite geomagnetic condx for CQWWSSB. Looking good for DX on higher bands grafana.gafner.net/goto/hhxK1pg... is.gd/5WLoHJ #hamradio #cqwwssb #hfpropagation #spacewx #spaceweather

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)

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

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

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...
