At NARC we cater for a wide variety of interests within the hobby of Amateur Radio and our membership ranges from complete beginners to those experienced in operating and building electronic equipment.
Beginners have the opportunity to participate in courses run by NARC for all three licence levels. The Social aspect of the club is thriving with family events such as Radio by the Seaside and Radio Active weekend, NARC also operates in various contests and in the last two years we have won the RSGB Club Championships on 80m.
We have a comprehensive club programme running throughout the year, the complete list can be seen on the diary page. We also try to cater for youngsters with our "Bright Sparks" evenings when we dedicate an evening to assist the younger members in construction and operating techniques. We offer club trips and also run the annual Barford Radio Rally which falls on July 3rd 2016
We have a shack at NARC which has HF, 6M , 2M and 70cm along with laptop for data modes and CW on HF along with D-STAR on 70cm the shack is open on informal evenings. We also have a comprehensive loan system available to members including TX/RX, Test Equipment and a library. We run nets on GB3NB on a Monday evening and HF nets with our Twinned Club in Koblenz.
So take look around and we look forward to seeing you at the club one evening.
This week was dominated by extensive geomagnetic disturbances thanks to ongoing coronal hole activity on the sun. Coronal holes are areas with open magnetic field lines that allow plasma to escape as a high-speed stream.
This plasma impacted the Earth causing aurora and unsettled HF conditions, especially on paths over the poles.
The K index was pushed up to five and even six throughout the latter half of the week, bringing a mixed bag of HF propagation.
At times the maximum usable frequency was suppressed with noisy HF bands and very poor propagation. But there were highlights, with enhanced HF propagation at times, up to and including 21MHz. DX heard in the UK included D66D Comoros and S9BT Sao Tome.
Next week NOAA predicts very unsettled geomagnetic conditions for Sunday and the first half of the week and unsettled conditions for the remainder.
The solar flux index will be in the range 80-85, with a chance for C-class solar flare activity.
Because of the way HF conditions can change quickly, we suggest keeping a close eye on the twenty to fifteen metre bands as short-lived openings may occur at any time during daylight hours.
As we head into late September, DX is being worked and conditions will continue to improve.
VHF and up
The end of last week saw the finish to very unsettled weather. This week, high pressure is due to build to the east of Britain over Scandinavia and eventually link up with another area of high pressure over Biscay.
This should provide some modest Tropo prospects at times for many areas, although Ireland and western Scotland may remain too breezy for any significant inversions to develop.
The limiting factor of the Tropo may well prove to be fairly dry low-level air under the inversion, so the better conditions will be seen when there is evidence of moisture near the surface, like fog and mist.
Wednesday sees the Draconids meteor shower. Don’t get too excited though as it only has a low zenith hourly rate.
It’s a bit of an odd one in that the radiant is highest as darkness falls, giving higher meteor rates in the evening.
Moon declination reaches minimum on Friday so EME moon windows are short. Add this to high losses and this is a week for EME system maintenance and improvement.
The Sun’s declination is falling giving a maximum sun elevation of 35 degrees this week, so now is the time for sun/cold sky measurements before it’s too low to clear ground noise.

September 3rd and 4th: SSB Field Day - CANCELLED
We regret that this event has been cancelled through lack of interest and support (just 2 members volunteered to help set up and operate the station).
Last Wednesday we held an impromptu Raspberry Pi workshop and display - special thanks to William, Nev, James, Phil, Bruce and Tammy for bringing their projects in to display and discuss with members.
As promised I have put together a buying guide of some of the most common Pi components and as well as the handouts I printed I have shown the main contents below.
On wednesday our thinking was that we will have an infiormal Pi and Chips evening to bring projects together each month on an informal... let me know you think?
Raspberry Pi & chips group - NARC group buying
The following is a list of popular Pi products and software from a selection of suppliers which I am offering to buy as a convenience and service for members for a limited time. Everything is offered at cost price given a few pence either way, but some prices fluctuate daily so I reserve the right to increase or decrease if that happens when I place an order. Many of them i will order through my trade suppliers like Farnell and RS and of course you are welcome to look at their range and prices, but note most web prices for them are exclusive of VAT which I have added to the prices below. I only want the money for them when I give them to you but please pay in cash by exact amount as a business has to pay fees on cheques (£1.50) and credit cards (typ 3%) and as I said these items are being charged at cost. I also dont mind ordering a few different bits and pieces at the same time as long as you give me details of part number and price and they are all together.
Of course if you are happy buying on the web then I would encourage you to order online and get them delivered direct to your door - I am purely doing this to help those who can’t and also to take advantage of some quantity buying prices we can do as a group.
Ucreate starter kit: Pi3, 16GB card, keyboard, mouse, case, PSU, HDMI & network cables CPC £62
Raspberry Pi 3 Model B 1GB RAM R/F £34 each or £31 if 5 or more ordered
Raspberry Pi camera V2 R/F (state IR or NoIR) £22.80
Raspberry Pi 3 + V2 camera bundle F £48.00
Official Raspberry Pi 2A power supply R £4.80
Official Raspberry Pi 3 case - Raspberry & White £6.60
Raspberry Pi 3 case black with clear top for HAT etc £5.70
HDMI monitor lead - cheapest place I have ever found bar none is Poundland (yes £1!)
Mike Richards G4WNC gave a talk on using the Pi with radio at the club and the following are his SD/MicroSD cards preloaded with the application and Pi operating system where appropriate. Instructions will also be supplied. You can order direct from Mike at £8 each or club bulk orders of 10 or more mixed cards he will supply to one person at £6 each. They are all supplied as 8GB MicroSD cards inside an SD card adapter they will work with various Pi’s and as the price of blank cards alone are £4 or so represent great value even if eventually you decide to wipe part or all of the card and use it for something else!
FLDIGI – Digital modes software (latest version). I have two versions. One is configured to work with the lower powered Pi 1or Pi Zero and so only supports PSK operation. The second version supports all the FLDIGI digital modes and works on the Pi-2 and Pi-3.
RTL Dongle Server – This is a single SD card that works across all the Pi models and allows you to remotely locate a Pi and a DVB/T SDR dongle and relay the IQ data back to SDR# via an Ethernet connection. It can work with a Wi-Fi link but I don’t recommend that as you have to slow the IQ rate down to the minimum.
PiAware – A variation on the RTL Dongle server but in this case it runs ADS-B software to receive position reports from aircraft and report the results to the FlightAware site. You can also access the Pi locally to see activity. This needs an Internet connection to operate.
MotioneyeOS – This software allows the Pi- & Pi camera to operate as a remote security/wildlife movement triggered camera over network. 3 different cards for Pi1/Zero, Pi2 or Pi3

Hopefully most club members will be aware that Norwich and Koblenz are twinned cities and to help perpetuate the good relations that we enjoy, there is a regular amateur radio sked each month. This occurs on 7.135MHz, plus or minus QRM, on the second Saturday of the month. The time is 1000hrs local time with check-in or talk-back, if necessary, on 145.250MHz. You will, no doubt, have seen pictures on the Club web site in the Gallery, showing the gathering we had with visitors from the Koblenz amateurs. If you haven't, take a look on the web site and you will see them there.
The latest sked was last Saturday and unfortunately, G3LDI was the only attendee from the Norwich side. We had a very good QSO however, and it would be nice if a few more of the NARC members ( committee members too? ) took part. There were four on from Koblenz. During the contact Ralf DM5RS told me that they were considering another visit to Norwich in 2017. He said that they would like to visit the Club and may also be able to provide a talk for us. Dates have not been suggested as yet but they will inform us as soon as they know.
Ralf has sent some pictures from their Field Day contest and they will be in a folder on the NARC web site soon. The next sked is on Saturday October 8th at 1000 as usual on 7135KHz. Please try to join in.
The National Hamfest is on this Friday 30th September and Saturday 1st October and being held at the Newark Showground. (www.nationalhamfest.co.uk)
We are running a spacious coach which will be leaving at the times and places below.
Representing our club...
As I said last week NARC has been shortlisted with 2 other clubs for the National Large Club of the Year and the winner will be announced and presented at 2pm on Friday at Hamfest, so with fingers crossed if you are going to be at Hamfest please wear your club short or badge as there will be a photo call for the winners. Whether we win or not, congratulations to everyone who helps to make our club what it is.
Forgotten anything? If you have booked but forgotten where you asked to be picked up from or where the pickups are this is the complete manifest of all those who have booked below. If you want to change anything please let me know immediately as we will be checking everyone in at the stops shown to make sure we do not miss anyone. The coach will be leaving promptly at these times - if you are unwell and unable to go or you are going to be late PLEASE CALL ME on the number below from 0600 Friday out of consideration of everyone else on the trip.
The coach will be leaving Newark at 4pm, so allowing for Friday traffic and a comfort stop on the way home everyone shouid be back at their pickup points by 7.30pm.
FINAL Hamfest Manifest - Friday 30th September 2016
73, David G7URP
As you know NARC won Large Club for region 12 in May and I have just received the exciting news from RSGB general manager Steve Thomas that we are one of 3 clubs shortlisted for the National Club of the Year award! It is a wonderful achievement for the club to come in the top 3 clubs of the country and I am very proud and thankful to everyone, members and committee alike, who help make the club what it is.
The result will be announced at the National Hamfest next Friday 30th September at 2pm and if we are fortunate enough to win we will thankfully have at least 40 people there to receive the award because of our coach trip that day.
Fingers Crossed, but whether we win or not it is wonderful recognition.
