Advance Course Notes

I try to be careful and never use the club for any personal gain, but I hope you do not mind me sharing the fact that we have just upgraded my DCP works to all LED lighting and because of this we have over 50 x square fluorescent lighting fittings with matching 18W tubes and diffusers which I have to get rid of quickly as they are everywhere!

Of course I realise fluorescent lighting is not the latest tech, but I feel there must be clubs, workshops, village halls etc which could use them to upgrade what they have. They are free to a good home or £75 ono if sold to a business (which will go to charity). 

So please if you know anyone who could benefit from these please forward the following link as I must clear them soon or next week will be forced to take them to the local scrapyard which seems wrong for good working lighting.

The following is the gumtree advert - also advertised on Facebook marketplace and ebay.

Thank you, David G7URP

 

 
My name is Tom Foxe, retired lab technician/TV repairman. I have been repairing small domestic appliances for decades & would like to meet others interested in starting an occasional "pop-up" repair cafe in Norwich. Currently about a dozen people have declared an interest and I'll soon arrange a meeting so we can decide how to proceed. If any of your members are interested, check out Restart Project online, there are lots of sites around the world where people bring computers, mobile phones, domestic appliances and more to be mended, or even to learn how to mend them. We currently have a couple of electrical people and a no. interested in doing textile repairs. I plan to go to the nearest Repair Cafe in Soham Cambs. on Sunday 15th March to see how they do it, meantime I'll be getting advice from rfolk Voluntary and Men's Craft, who operate the Pittstop above the Men's Shed in Pitt St Norwich. We won't be doing electrical repairs until we have an agreed safety policy, insurance and more.... 
I'd love to hear from anyone who's interested in giving it a go.

As you may have seen the results of the CW AFS have been published where NARC Team A came a creditable 4th in the Local Club section.

Our team B also came in at 10th and team C 30th (only 3 members) out of a total of 55 entries in that section. A good result and well done to all that took part.

Of note was that Peter M0RYB/P kept up his usual QRP performance coming second in that category. Also Phil G4LPP, still in the ‘learning’ process of Morse, made it into team A with an excellent score.

As we are rapidly approaching the start of the Club Championships with SSB on 3rd Feb I will shortly publish the final listings of the two teams taking into account any new calls to be added to the list after further discussion at the club tonight.

Future HF events:
.
This weekend on Saturday 18th January 2020 at 0900utc it is the SSB HF AFS, last of the HF AFS events .
.
Ensure that you are familiar with the rules at the link below:

Have lots of fun with your chosen contests in the coming 12 months,

 

February isn't far away and on Monday 3rd February the 80m Club Championship begins again for another 18 contests.

.
Also the RSGB 1st 1.8MHz contest is 8th February 1900 to 2300utc, so you'll need to get those 160m dipoles up in time.

8th and 9th it is the CQ WPX RTTY contest, 48hours starting 0000utc on 8th February - good for DXCC hunting early in the year.
.
For future events keep looking at:

RSGB VHF Contest Calendar:
https://www.rsgbcc.org/cgi-bin/readcal.pl?year=2020
.
Some rule changes have also been implemented so always study the current rules for this year's contests and don't assume that you know the rules because you last read them in 2015 !
.
Another useful source of non-RSGB and WW events can be found here in Bruce's (WA7BNM) weekly listings:

Again, always download and study the rules for other countries' contests as they often have different terms and conditions than those we are used to.
.
Two more to keep you contesting:
.
24th January at 2200utc to 26th January at 2200utc it is the CQ WW 160m CW contest.

25th January at 1200utc to 26th January at 11:59utc it is the first of BARTG's HF RTTY Contests.
.
.
VHF events:

The Final event in the 2019/20 AFS Super League takes place on Sunday 2nd February from 0900utc to 1300utc
UK Activity Contests.
.
February 144MHz UKAC on Tuesday 4th February at 2000utc. NARC had 3 logs submitted in January in a total of 264 logs.

Tuesday 11th February is 432MHz UKAC.

Thursday 13th February is the 6m (50MHz) UKAC

Good Luck and always mention Norfolk Amateur Radio Club when submitting your contest scores.

This week we have DarrIn KE9NS via Skype giving us a talk on Power SDR, PowerSDR is the Microsoft Windows based client software created by Flexradio to operate their software defined radios.

As usual, we meet from 7pm and DarrIn's talk starts straight after notices at 7.45pm.

Thanks to all those who have recently renewed their NARC Membership full details can be found here to renew your membership at NARC.

HF News

We had another pretty uneventful week with zero sunspots, but no major geomagnetic disturbances.

The K index rose to three on Thursday morning due to the effects of the solar wind, but the ionosphere was otherwise calm geomagnetically.

I said last week that there had been some winter Sporadic E, which had livened up 10 metres. I also said there had been no SSB activity of note on the band and was promptly corrected by Tony M0IQD who sent a copy of his log.

This showed that he made more than 15 SSB contacts on January the 8th, including Norway, Sweden, Poland, Germany and even VO1FOG in Newfoundland. Keep an eye open around 28.450-28.495MHz for SSB openings.

He also suggested that the Facebook group “10 Metre UK Net” was a useful tool for 10m operators. I’m only too happy to pass that information on.

Next week NOAA predicts the solar flux index will be in the range 70-72, reflecting the current state of the solar cycle. It also predicts quiet geomagnetic conditions all week, so the ionosphere should be settled and showing seasonal norms in terms of propagation.

According to Propquest, daytime critical frequencies as measured by the Chilton digisonde, are generally in the range 4.1-5.3 MHz, which suggests that 80m remains best for inter-G contacts, with 40m being restricted to longer paths such as G to GM. Nighttime critical frequencies are generally around 3.1-3.6 MHz, so 80m propagation may be marginal over shorter distances, but better over 500km or more.

Daytime F2 layer openings are generally up to 18MHz with the 20 metre band being more reliable.

Weather charts show that the jet stream will remain strong over the UK and Europe next week, which may be an indicator for Winter Sporadic E, although the season may be ending – more of this in the VHF section.

VHF and up

High pressure has started to reassert itself over southern Britain and improved Tropo conditions will probably kick in from today into early next week. Paths into the continent and south past Portugal towards the Canaries might be worth a look, in view of recent performances.

This positive Tropo pattern could hold into midweek, but thereafter the models show a collapse of the high back towards the Azores, allowing room for a colder north-westerly to bring stronger winds and a risk of some wintry weather across eastern areas.

But other models confine the cold outbreak to the northern half of the UK only.

There is always scope for some winter sporadic E and the jet stream pattern may favour paths into western Europe and the western Mediterranean, particularly for digital modes like FT8, but it could also be worth checking for CW and SSB on 10m too.

The cold northwesterly with its wintry showers may excite the GHz fraternity towards the latter part of next week as heavy showers move down the North Sea and Irish sea bringing some rain scatter propagation. The good thing about winter rain scatter is that the showers are not diurnal like in summer and usually maintain activity throughout the day and night.

Moon declination is negative and reaching a minimum on Thursday. Path losses continue to rise all week, and the very high 144 MHz sky noise midweek means it's a poor week for EME.

There are no major meteor showers this week so continue to look for random QSOs in the early morning around dawn.
