Ofcom has updated the guidance document What you need to know as an amateur radio user and the Ofcom EMF calculator. The guide provides an overview of what you need to do to comply with Ofcom’s EMF licence condition and is much simplified from the earlier version. Links to all of the documents and calculators can be found at

A slow-scan television ARISS event is scheduled between the 21st and 26th of June. Transmissions from the ISS will be on 145.800MHz FM using PD120 SSTV mode. The SSTV images will be transmitted continuously. Transmissions will start at or about 0940UTC on the 21st and will end by 1830UTC on the 26th. Signals should be receivable on a handheld with a quarter-wave whip antenna. Use 25kHz channel spacing if available.

Since reopening just over two weeks ago, the RSGB National Radio Centre at Bletchley Park has welcomed more than 3,800 visitors. With the improved signage and Bletchley Park interactive map, the NRC is typically seeing close to 50% of the Park’s footfall. The RSGB would like to thank Martyn, G0GMB and the NRC volunteers for making this possible. The NRC is open every day, except Wednesdays, to pre-booked visitors to Bletchley Park.

Sad news next, particularly for those in Region 9, as Tom O’Reilly, G0NSY became Silent Key last week. Tom volunteered for the RSGB as Regional Representative 9, covering London and Thames Valley from 2016 and as a District Representative before that. Our thoughts are with his family, friends and colleagues at this difficult time.

The lecture programme for the weekend of the virtual Ham Radio World Weekend has been announced for the 25th to the 27th of June. Go to and click on the advert for the event at the top of the page. There are lectures in English and these can be seen by their English titles.

The Summer Sale in the RSGB Shop has started and will run until the 18th of July. Go to to find out more.

To increase participation in the FMH Portable Operations Challenge in September, parallel regional or local group competitions are being encouraged by Ed, DD5LP. Those who would like to do this for their group or region should send an email to The regional organiser’s callsign and the geographic area or group of people to be covered should be in the email. Full details of the Portable Operations Challenge can be found at

Slovenian Amateur Radio Union will celebrate the country’s 30 years of independence by issuing a special award. Between the 26th of June and the 31st of December, Slovenian amateur radio stations can add the number 30 into the suffix. For example, S50ZZ would become S5030ZZ. Search for Slovenia Contest Club using your favourite search engine and click on the Union Jack flag to read all the qualifying details in English.

Now the radio propagation report, compiled by G0KYA, G3YLA & G4BAO on Friday the 18th of June.

A large coronal hole returned last week and started to become Earth-facing on Monday the 14th. The high-speed solar wind stream from the hole impacted the Earth on Tuesday evening, pushing the Kp index to five. Luckily, conditions returned to normal by late Wednesday and the Kp index was down to two or three thereafter. It now looks like we are free of coronal hole effects for the time being.

Sunspot-wise, region 2833 put in an appearance. Its effects on the ionosphere have been minimal with the solar flux index stuck at 76 on Thursday the 27th and the sunspot number at 11, representing one spot in one group.

HF propagation has been adequate rather than outstanding, with the real talking point remaining Sporadic-E. Conditions on 10 metres have been good with long, solid openings to Europe popping up each day. Do make the most of these, as F2-layer openings on 10m may be harder to find once the Sporadic-E season ends.

Next week NOAA has the SFI at around 80 and quiet geomagnetic conditions with a Kp index of two. We are still not seeing the ramp-up in sunspot activity that we would like, although fingers are crossed that this Autumn might be more positive.

In the meantime, make the most of the Sporadic-E openings, particularly on the higher bands such as 12 and 10 metres. These openings can affect lower HF bands too, although it is sometimes hard to distinguish them from F2-layer openings.

So please don’t ignore 15 metres and lower at this time and look for short-skip contacts on these bands as well.

And now the VHF and up propagation news.

It looks like the majority of next week will see low pressure predominating with further periods of unsettled and potentially thundery weather. The pattern places the main area of low pressure over or just west of the UK, forcing a thundery showery southerly flow across the country. There will be some interludes when brief ridges of high pressure show up, especially in southeastern areas, but overall Tropo will not be high on the list. So, apart from some rain scatter prospects and the occasional extended sea path Tropo across the North Sea or English Channel, it will mostly be a week for chasing Sporadic-E.

The northern part of Europe and Scandinavia have a good jet stream flow and this extends into northern Russia, making it worth checking those DX paths into the Far East and Japan. The other region looking well favoured with jet stream patterns is to the south into Spain and Portugal.

We are in peak season for Sporadic-E, so keeping a regular routine of checking the bands mid-morning and early evening is the best procedure to follow.

The Moon is at perigee on Wednesday so path losses will be at their lowest. Sadly, with minimum Moon declination on Friday, visibility windows and peak Moon elevations will also be at their shortest and lowest of the month.

The June Bootids meteor shower peaks on Sunday 27th. This shower, although normally small, has a reputation for outbursts of activity. Until then, continue to look for the best random meteor scatter propagation around dawn.

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