Last Updated: 31 July 2021

Every week since March 2020 we have been showing you the shack of a NARC member and ask you to guess whose shack it is.

But this weeks shack below is the LAST SHACK - unless you have not sent your shack in yet? If so you please send it to us now otherwise this competition will finish and we will start a new one. Thank you so much to everyone who has entered into the spirit of this for and kept everyone guessing and entertained for so long!

So have a close look at the photo below  - do you know which member this weeks shack belonged to?

It was taken when they were based in Wymondham back in the 1980's...

If you think you know whose shack it is (or just have a guess!) please email David & Tammy with your guess to  This email address is being protected from spambots. You need JavaScript enabled to view it.  by 3pm on Wednesday and be sure to watch NARC Live on Wednesday evening at 7.30pm to find out who's it is!

STOP PRESS : THIS IS THE LAST SHACK - UNLESS YOU HAVE YOURS YOU WANT TO SHARE -  IF SO SEND IT NOW !

After a different shack on every show since March 2020 we have now run out but will keep showing them until you send no more, so if you would like us to feature your shack on this fun quiz please send it to us NOW as we will be changing to a different competition once we have used the last shacks....

We really are on LAST shack now unless there is anyones shack we have not featured before. If you have already had your main shack featured but want to send us a funny, old or alternative shack please do so as we are going to do a special 'Shack Wrap' at the end of the series!

Last weeks shack belonged to Stephen M6KYF - Congratulations to Chris G4CCX who was the only person to get it right!

Propagation News, Friday 30th July 2021

HF News

Last week the Sun was bursting with sunspots with a solar flux index in the high 80s. But by Thursday we were looking at a different picture with zero sunspots and a solar flux index of 79.

We also had a geomagnetic disturbance thanks to the arrival of a high-speed stream from a coronal hole late on Wednesday. This pushed the Kp index to four with the solar wind speed remaining elevated until at least late Thursday.

The disruption triggered a short-lived ionospheric enhancement with maximum usable frequencies over a 3,000km path reaching 25MHz at 20:40 UTC on Wednesday, according to Propquest and the Chilton Ionosonde data.

But by Thursday morning they were struggling to reach 14MHz.

Propagation earlier in the week had been quite good with extensive openings to the Far East on 17 metres. Rodney G0CBO reports working a host of stations, including Japan and Kazakhstan, using just 40W FT8 to a vertical. Meanwhile, Steve G0KYA worked 8N8OLP, the Tokyo special event station for the Olympics, using 50W FT8 to a quarter-wave vertical on 20 metres.

Next week NOAAś Space Weather Prediction Centre predicts the solar flux index will remain in the mid-70s. It also has the Kp index at a maximum of two or three, reflecting the lack of solar coronal holes.

There is the possibility of a geomagnetic disturbance this weekend caused by material arriving from a small coronal hole on the Sunś equator, but its effects may be minimal and short-lived.

VHF and up

Last week provided some excellent rain scatter QSOs for GHz Bands operators. The heavy showers across the South and East of the country coincided with not one, but two GHz contests.

During the all-day Sunday, UK Microwave group event, many stations reported working into the North of England from the South and East Anglia via backscatter from a line of heavy showers extending from Ipswich down to Southampton.

The coming week looks very similar to the last one with an unsettled weather pattern offering further heavy showers or thunderstorms and longer periods of rain. This will favour rain scatter while there is little prospect of any high-pressure systems returning to produce Tropo.

Regarding Sporadic-E, the unsettled weather suggests there will be jet stream activity to help along any late-season interest. Remember the season can extend into early September, so plenty of time to fill in any missing squares this year.

With positive Moon declination, this week we’ll have long Moon visibility windows, but with apogee on Monday, path losses will be at their highest.

Random or sporadic meteor rates are still high, but there’s a big shower on the way. Get ready for the largest shower of the year, the Perseids. This peaks on August 12th/13th with a zenithal hourly rate of 100. Find out more about this shower next week

We urgently need your feedback on whether you would you like to see the more serious Trophy Foxhunt 'televised' in August?

Although everyone who competes enjoys taking part, it is hard for us to tell whether you at home would like to see another full hunt next month or just highlights, so although the Trophy event will happen we will only cover it live on NARC Live if you, our viewer, tells us you would like to see the next one.

Please drop Tammy and me a quick note by clicking on this and saying whether you would like to see next months trophy foxhunt live or not:  This email address is being protected from spambots. You need JavaScript enabled to view it.

And do not forget Roger and we desperately need contacts for more radio talks for the autumn as we have been using 2-3 times more formal talks and evenings than we normally would.

Many thanks
