Welcome to week one hundred and thirty five of NARC’s contest news.
Results:-
On VHF
The results of the 144MHz UKAC of 2/4/2024 were released on Friday 12th April. We had managed 10 entries for this one which is a good turnout. Thanks to those who entered for us. Leading station in our group once again was Stewart G4AFF so congratulations to him but excellent results also from those with only colinears or indoor aerials. Every point helps! We remain in 4th place overall on 2m with 16,194 points. Wirrall and District ARC are in 3rd place with 21,007 points so are within possible target range! Link to results here
Despite no UKAC SHF entries this year from the club we remain in 4th place overall - Link here
On HF
No new HF results this week of which I am aware.
If people are entering other contests of whose results I am obviously unaware please e-mail me to let me know the outcome and I'll mention it here.
Contests:-
On VHF
The 1.3GHz UKAC ran on Tuesday 16th April. NARC managed 4 entries. G4AFF, G4LPP, G3YLA and G4DYC. Things have improved for the Mattishall contingent as rather than just working each other across the garden fence they each managed 4 QSOs so there's progress there! Best DX for both myself and Stewart G4AFF was GM4JTJ at roughly 505Km. Link to claimed scores here
The 70MHz UKAC ran on Thursday evening 18th April. Conditions were well down with a weather front across the country and signals generally were borderline with the addition of deep rapid QSB. To cap it all, there was a lot of noise about especially here to the North West. I expect several UBNs. 5 NARC members are known to be submittinng logs and others were on the air. Link to claimed scores here
On HF
The 80M CC SSB ran on Wednesday evening 17th April. Conditions were good as was activity and despite SSB being few people's favourite of the CCs we managed 15 stations and some good scores, we also had a surprise new entry from Steve, G3EVA, welcome! Overall it is noticeable that scores are going up gradually for all team members. Link to logs received here
A report from John G8VPE concerning the Spanish (URE) RTTY contest of 6/7 April. He comments that local activity was poor with only himself and Bob, 2E0OBO spotted in the logs received. John worked 47 stations.
I've had no reports of anyone working any other HF contests last weekend. Please let me know if you were and I'll put a summary in next week's news.

Contesting can be great fun but I know there's a reluctance to step into unknown waters. It's a great way of improving many aspects of our hobby including one's own performance and the quality of your station. If you have any interest whatsover please call in to the contest net on Friday evening at 9pm on 145.250MHz FM or speak to any of the regular contesters on 450. Or indeed email me!

HF News
Last week saw a welcome return of sunspots, but unfortunately, it also brought unsettled geomagnetic conditions.
By Thursday the 16th the solar flux index was back above 200, hitting 217. Compare that to the previous week’s 131 and you can see that there is a lot more activity. But with 12 active regions visible it looks like we could be in for a bumpy ride over the next seven days.
The Kp index hit five on the evening of Tuesday 16th April after the interplanetary magnetic field or Bz swung southwards, sparking visible aurora in the UK as far south as Dartmoor. This impacted the ionosphere, pushing MUFs over a 3,000km path way down, with recovery not showing itself until 09:30hrs on Wednesday the 17th.
Ten metres is struggling to open at times, although you may find FT8 still passing weak signals. SSB operators might be better advised to look at 12 and 15 metres which may provide richer pickings.
A small coronal hole on the solar equator is also now facing Earth, which might cause an increased Kp index late on Friday the 19th or Saturday the 20th.
Next week NOAA predicts that the SFI may decline to be in the range of 170 at the beginning of the week, falling to 135-140 at the end. The risk of an M-class flare is currently put at 75%, with an X-class event at 20%. Despite this, NOAA predicts the Kp index will be around two all next week, although there is a chance that a flare and associated CME could scupper that completely.
If we do get a CME we can expect the Kp index to rise roughly 48 hours after the event, perhaps hitting five or more and possibly sparking visible aurora from the UK again.
Overall then, it's good news on the sunspot front, but not so good for geomagnetic activity, which could see MUFs fall if any solar flares and CMEs come to fruition.
VHF and up
The weather is likely to remain in a fairly unsettled state, despite a temporary high pressure moving across the country this weekend. This may bring some Tropo, but it’s a cold air high and probably not the best for enhanced VHF conditions, except for localised overnight or early morning temporary lifts.
The rest of the time there will continue to be an unsettled flavour to the weather so this leads to the possibility of rain scatter on the GHz bands, especially if we get heavy “April” showers.
This first weekend coincides with the peak of the Lyrid meteor shower which peaks on Sunday night, the 21st-22nd April, so it’s worth checking the usual meteor scatter frequencies, especially on Sunday and Monday. If you are not familiar with meteor rates and variations from day to day, then visit the excellent Radio Meteor Observing Bulletin at https://www.rmob.org which gives an hourly display from various locations around the world or try this page https://rsgb.org/main/technical/propagation/meteor-scatter/ on the RSGB website for many other useful links to meteor scatter resources.
The Sun has woken up a little since last week, and a few auroral flutter signals on the LF bands suggest we shouldn’t give up yet for this Spring. As usual, keep a watch for Kp index going above Kp=5.
The late April period can provide some fleeting early season Sporadic-E events, especially for 10m and 6m and a couple of weak 5MHz foEs or Es critical frequencies were noted during late afternoon on Wednesday the 17th on the Dourbes plot shown at https://www.propquest.co.uk/graphs.php
For EME operators, Moon declination goes negative again on Sunday, but path losses are falling as we pass apogee the day before, Saturday the 20th. 144 MHz sky noise is low, but rising to moderate by the end of next week.

Unfortunately the great British weather has finally caught up with us, and the site has become unavailable for use this coming Sunday 21st as originally planned due to waterlogged surfaces, so we have taken the decision to postpone the CRG Rally until July.
We are planning for Sunday 14th July (TBC) to hold the rally, still at the Foxton Village Hall, awaiting final confirmation from the venue.
Please do share this information with your friends and fellow radio amateurs who may have
been planning to attend.

As many NARC members will know, every year we host an 2 day event called RadioActive on the first weekend of June held at our place in Gt Ellingham near Attleborough. As well as two active contest stations we host workshops, talks and activities at DCP, not to mention Tammy and my Sunday Roast too! A relaxing informal family welcome event.
But I would really appreciate some help: As our Forum has been delayed until a few days before RadioActive I have lost the opportunity to get your feedback on what you would like to see at RadioActive so I would really appreciate some requests and ideas. The event is particularly ideal for things that do not suit the two hours we have on a Wednesday evening at CNS.
We usually run a construction project (inc etching circuit boards) but unfortunately this year Nick who has done this for several years cannot make it, so could you host a small construction project workshop?
Or do you have a suggestion for something you have made and think others would enjoy - circuit wise or antenna?
We have a small mechanical workshop at our disposal as well as work benches and test equipment.
Or maybe a talk... or film ...
Please get in touch with anything you would like to see at RadioActive 2024!
Thanks. 73
David G7URP & Tammy M0TC

MMANA-GAL is a really clever software tool for analyzing antenna and tonight our own Steve Nichols G0KYA will be taking us through it and demonstrating how useful it can be for radio amateurs.
As Steve is one of our club members and lives relatively locally he will be making his presentation at CNS School with an in person talk which will start just after notices at 19.30.
The school will be open from 1900-2130 - Cold drinks and biscuits will be available to purchase and there is also a hot drink vending machine in the adjacent canteen room.
Members Forum
The Members Forum postponed from last Wednesday will now take place on Wednesday 29th May.
As originally promised this will be both an in person and online streamed event so that every member can get involved with their ideas and suggestions for NARC
