A series of solar flares can cause a transmission blackout on KV
The sun continues to be active. Sunspot AR3664 it threw up four very powerful eruptions in a short time. They will reach Earth on May 11 2024. We examined and summarized four antenna performance parameters in relation to peak angle variations., that the first three can combine. Even if not, each of them can cause geomagnetic storm class G3. In case of connection up to G4. This should also produce an aurora in the mid-latitudes of Europe and the US.
Such geomagnetic storms are capable of creating a temporary or complete loss of radio signals on KV. In case, that you too have noticed dropouts or even a complete loss of signal, know, that it could have been caused by the increased activity of the Sun.
TIP: WSPR Propagation HB9VQQ https://wspr.hb9vqq.ch
This website allows you to access and visualize more than 5 billion records in the WSPR database, which extend up to a year 2008! WSPR is the perfect tool for long-term propagation analysis, but also for a quick check of your distribution conditions.
At every moment, day and night, are active worldwide more than 800 WSPR transmitters and receivers. From the data and comparisons, it is possible to find out how well and at what time the shortwave bands are open.
This web portal will provide you with answers to your questions, for example
- What is the best band and time to connect X to Y?
- What is the trend of the spread over the time period T?
- How local is the spread?
- What is the effect of large solar events on propagation conditions?
- Comparison of antennas and QTH
- It also indirectly enables the comparison of real propagation between two stations. Example: if both stations broadcast WSPR at the same power in an identical time period, a comparison can be made from the received reports, which antenna and location (QTH) it is better for broadcasting.
