The news headlines:

• The RSGB’s annual Convention is coming up in October
• National Coding Week returns in September
• Exercise Blue Ham is taking place this week

This year, the RSGB’s annual Convention will take place from the 11th to the 13th of October. What would you like to see at the Convention? This year the Society is offering everyone the opportunity to propose a presentation, a topic, a practical session or a project to share. Are you involved in some new research? Have you discovered something new in amateur radio that you’re keen to share? Are you part of an interesting project that will take amateur radio to new audiences? Or have you helped to make amateur radio more accessible to people with different abilities? If you’d like to offer, or suggest, a presentation on these, or any other topics, please send your proposal to the Convention Team. As part of its strategy, the RSGB wants to ensure that this prestigious annual event not only meets the needs of its members but also helps every radio amateur to share their love of the hobby with others. The deadline for proposals is Wednesday the 3rd of July so it is important to send in your ideas as soon as possible. Email convention@rsgb.org.uk and make sure you put ‘Convention proposal’ and the topic in the email title.

National Coding Week runs in September. Coding – or programming as it used to be called – is used in a range of amateur radio activities. This year the Society would like to develop its activities further by appointing a volunteer National Coding Week Coordinator. Could you encourage people, help them with their ideas and work with HQ teams to publicise and support activities? If you love computer programming and think you could help others enjoy it through amateur radio, why not think about offering an activity or volunteering to be the RSGB’s National Coding Week Coordinator? Get in touch by emailing strategy@rsgb.org.uk

RAF Air Cadets are running the ever-popular Blue Ham Radio Communications Exercise, on the 60m band, between the 17th and 21st of June. Subject to your licence conditions, the Blue Ham team hopes that you can put some time aside to join in with the cadets and staff who will be ready to take your calls. The Blue Ham Team will issue you with a participation certificate if, during the period of the exercise, you contact 20 or more special military cadet callsigns with an MRE prefix. For more information visit alphacharlie.org.uk  Please note that only Full licensees may operate on the 60m band.

The May 2024 edition of the IARU Region 1 Monitoring System Newsletter is now available. The newsletter contains details of intrusions into amateur bands, and you can access it via tinyurl.com/IARUMAY24

This year, the popular British Inland Waterways on the Air event will take place between the 24th and 26th of August. The event is open to amateurs who use canals, towpaths, rivers, lakes or reservoirs for work or recreation. Registration for the event is now open. To sign up, visit Nunsfield House Amateur Radio Group’s website at nharg.org.uk  and follow the BIWOTA 2024 link.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 13th of June 2024

No sooner do we say that conditions will remain good than the Sun emits an X-class solar flare! Such is the challenge of writing propagation predictions.

Nevertheless, after the X1.5-class flare on the 10th of June, things settled again and, at the moment, there are no incoming coronal mass ejections, or CMEs for short, to report. With a Kp index of less than 1 on Thursday the 13th, and a solar flux index of 165, it looks like HF conditions could be quite good.

However, the Sun’s proton flux has increased and is close to the 10 million electron volts warning threshold. This means that paths through the polar regions might be disrupted. Protons can herald the arrival of a CME two or three days later, although NOAA is not predicting any disruption.

On the 13th of June, the critical frequency was between 7 and 8MHz, meaning a maximum useable frequency over a 3,000km path of around 21 to 24MHz. The 10m band will be open, mainly to Sporadic-E. However, F2-layer propagation on the 10m band will be sparse.

NOAA predicts the solar flux index will fall to around 155 today, the 16th, before climbing again to around 195 in a week. Geomagnetic conditions are predicted to be quiet all week, but that may be because solar flares and CMEs are hard to predict at this point in the solar cycle.

As always, make hay on the HF bands while the Sun shines! And make the most of the Sporadic-E propagation on the higher HF bands as June is probably a peak month for this.

Finally, the latest sunspot data show that the average sunspot number for May was 171.7, the highest in 22 years. However, the ARRL reports that shortwave conditions were above average on only six days out of the entire month of May, and mostly poor on half of the days due to geomagnetic disturbances and solar flares.

And now the VHF and up propagation news from G3YLA and G4BAO

The current spell of seemingly endless, poor weather is struggling to provide much Tropo. The general theme is low pressure bringing weather fronts with rain or, if not that, then scattered heavy showers.

This again points to rain scatter for the GHz Bands as the mode worth exploring. There is just one glimmer of Tropo hope in that the latest model predictions are starting to inject the notion of a ridge developing over southern areas, initially around mid-week but perhaps more so at the end of the week. Although, it's fair to say that other models hang on to the low-pressure theme. That said, it's worth checking from the middle of next week onwards.

There are no significant meteor showers this week so continue to check for random meteors around dawn.

The solar conditions have continued to trickle charge the auroral oval with an occasionally enhanced Kp index indicating possible aurora. This is unlikely to be visible at this time of the year although, if you are outside with a clear view to the north, you might be rewarded with a seasonal look at noctilucent clouds to make up for it.

High-summer Sporadic-E propagation is providing daily contacts so it’s worth checking the bands each day. The daily blogs always have something to show on the 10m band and many days there are reports of contacts on the 6m band. Remember these openings are not always reachable from all parts of the UK. One of the characteristics of Sporadic-E is that at each end of the path the ‘signal footprint’ is very small. Even in a busy opening, signals may still pass you by but you should continue to monitor in case a Sporadic-E path opens up that does include your station at one end!

Moon declination is negative again from this weekend, ending today the 16th. EME path loss was at its highest at apogee on Friday the 14th. 144MHz sky noise starts the week low but rises steadily, reaching over 3,000 Kelvin on Friday the 21st.

And that’s all from the propagation team this week.
