Advance Course Notes

Wednesday 21st October - NARC Live!

Sadly Phil Holliday ZL3PAH has emailed to say he is unwell and cannot give his talk on his homebrew transceiver tomorrow..... get well soon Phil and we look forward to your talk at a later date

So we have arranged a last minute treat, and not only do we present the video on the adventurous DXpedition to T32C Christmas Island, but to introduce it we have one of the original Team members Chris G3SVL who will also answer YOUR questions about it live afterwards! Special thanks to Chris for agreeing to do this at such short notice and also arranging clearance for us to show it because it is normally only sold on DVD.

Plus we have regulars 'Who works from a shack like this', Tammys 'Little people' and we always enjoy sharing your news and view so please send them to us...

Autumn Series 80m Contests:
.
NARC are still just in the overall lead after the first four published results with a points difference of 998 points having had their previous lead of more than 4200 points reduced considerably by their nearest rival, the Three As CG.
.
Second CW contest:
Monday 5th October was the 4th event out of 9 in the series.
Conditions were good with plenty of inter-G stations operational and also a few regulars from DL, PA, SM, LY and YL.
This time 3As CG have made a very strong challenge submitting 15 high scoring logs.
NARC made a fairly good effort entering 19 logs.
.
The Three As CG have decisively won this CW event with a combination of skill and tactics in QRP and QRS operation.
They took the first positions in 3 of the 6 categories:
100W QRS G3TXF, 10W QRS G5Q (G3SVL), 10W QRP G4PIQ.
.
CW Results:
Three As CG 12727 points.
Norfolk ARC 9441 points. (down by 3286 points)
De Montfort ARS 5987 points.
.
Wednesday 14th October was a DATA contest once again.
Conditions at times were a bit of a struggle with many locals reporting better success on RTTY than on PSK63.
The foF2 critical frequency remained more or less on 3.5MHz for the whole event giving rise to some far from perfect operating conditions on 80m.
My antenna wasn't performing well at all with nearby contacts, it took at least 5 or 6 attempts to be heard by Malcolm G3PDH less than 10miles away and Jim G3YLA and Alan G8OO just could not obviously hear me at all in spite of numerous attempts at calling them. It was much the same for many other aborted G contacts, yet propagation seemed to be quite fair over longer distances to GI, GW, GM and PA.
We didn't have the benefit of Roger's usual high score this time since G3LDI had his Flex software setup scrambled due to an untimely Windows 10 update.
Entries have not closed yet so it is too early to predict any raw scores or positions, we just have to hope that we did our best.
Looking at the numbers of QSOs for each of the teams is it just possible that we may reclaim some of our lost points in the previous CW contest.
.
Thursday 29th October is the next event and will be SSB and we shall really need as many logs as possible.
If we are to stand any chance of winning this series we must have as many contacts as possible for this event.
It really is "All hands to the pumps, chaps or we're going down in flames."
Please submit a log on behalf of NARC even for just a few contacts, every point counts towards the end result.
.
The previously good 80m evening conditions with a high foF2 critical frequency have begun to show a downward trend as we move further into Autumn.
We could experience a sudden drop in inter-G propagation, even in mid contest, as October and November can be rather unpredictable on 80m. So, make a prompt start at 20:00 local time as propagation may worsen before the 21:30 finish.
You may check the foF2 critical frequency by visiting the Propquest website:

.
.
What's next?
The rest of the 80m Autumn Series dates:
Thursday 29th October SSB.
Monday 2nd November DATA.
Wednesday 11th November SSB.
Thursday 26th November CW.
Rules:

.
For those who really enjoy RTTY then this weekend is the JARTS WW RTTY contest.
Begins on Saturday 17th October at 00:00 utc and ends at 24:00utc on Sunday 18th.
Single operator on contest bands 80m through 10m, exchange RST and operators age (YLs may send 00 and club stations may send 99).
Rules below:
http://jarts.jp/rules2020.html
.
For VHF enthusiasts this Sunday (18/10/20) 0900 to 1300utc it will be the RSGB 50MHz AFS contest which is part of the cumulative AFS Super League Series for 2020/2021 for affiliated club teams of 4 operators.
Take care to read the Special Rules for this contest:
https://www.rsgbcc.org/cgi-bin/contest_rules.pl?year=2020&contest=2nd50MHz
.

Also on Sunday 18th October it will be the 80m RSGB ROLO CW Contest from 1900 to 2030utc.
ROLO is ROtating LOcator contest using 100W maximum on 3520kHz to 3560kHz.
Send RST, then for the first contact entrants send your own six character QRA Locator, eg. JO02UN.
For each subsequent contact send RST plus the Locator exactly as received from the previous contact, even if received as IO02UN, which is in the Atlantic ocean.
Accuracy is the essence of this contest and points will be lost for not accurately logging and re-sending the previously received locator.
Stay alert and please do not send your own locator for every contact.
Points from this contest will contribute to individual scores for the Annual HF Championship for 2020.
Rules at:
https://www.rsgbcc.org/hf/rules/2020/rolo.shtml
.
Other contests worldwide may be found on the website for the Contest Calendar by Bruce WA7BNM.

.
.
The Friday evening Contest Net at 20:00 local time will continue at the usual time but will change frequency to 145.275MHz to make way for a new GB2CW Beginner's class which will be held on the usual 145.250MHz frequency at 20:00.
.
Please help your club by operating in the Autumn Series contests on 80m.

HF News

We had a little flurry of solar activity last week, but it didn’t amount to much. Region 2775 decayed to a spotless plage and didn’t contribute at all after Tuesday the 13th.

A new region began forming while on the far side of the Sun and has turned into view off the east limb. The new region has been assigned active region 2776 and while a few spots are currently visible, so far only minor B-class solar flares have been detected.

Geomagnetic conditions were quiet with the Kp index fluctuating between zero and one. This was due to a lack of coronal hole activity, which meant the solar wind was subdued, generally keeping below 300km/s.

As a result, HF conditions have been quite good with lots of DX being reported by CDXC members. Patrice FK8HA in New Caledonia has been reported on 15m SSB, as has Mike 5H3EE in Tanzania on 15m CW.

October can also be a good month for 40m contacts into Australia and New Zealand. A number of contacts have been logged and Predtest.uk shows that 0600-0700hrs is probably best for a long-path contact and 1300-1600hrs might favour a short-path one.

Next week NOAA predicts the solar flux index will remain around 70, but the Kp index may rise, probably due to a returning coronal hole. It predicts a Kp index of four on the 20th and unsettled geomagnetic conditions which may peak around the 25th-26th with a Kp index of six.

So the conclusion is, make the most of the HF this weekend as the predicted conditions are likely to be poor for the rest of next week. Otherwise, look for auroral contacts on 10m next weekend.

VHF and up

This is a tricky week to predict, but hopefully with some chance of Tropo.

The VHF highlight though is the peak of the Orionids meteor shower on the morning of the 21st. With a ZHR of 20 it’s one of the larger ones of the year. The shower is already under way and runs from about October 2 to November 7. It’s caused by the stream of debris left behind by Comet Halley.

On the Tropo front, we ended last week with high pressure occupying much of the country and offering a chance of paths primarily between the UK and France plus across the North Sea to southern Scandinavia and Baltic.

Early next week a low tracks south-east from Iceland towards Denmark and introduces colder showery weather and a good prospect for rain scatter with heavy showers over the adjoining coastal waters.

After mid-week, a new high builds in from the west and leaves us in high-pressure Tropo weather to finish the week.

The Moon’s declination is negative all week reaching a minimum on Wednesday, so Moon visibility windows are short. The maximum Moon elevation in South-East England is just 12 degrees and as we passed perigee last Friday night, path losses will increase. The 144 MHz sky noise is high until the end of this week, above 2600 Kelvin on Wednesday, so in all, it is a poor week for EME.

Finally, keep an eye out for auroral propagation due to the predicted disturbed Sun.

GB7NB the D-STAR repeater located at Stoke Holy Cross run by the Norfolk Repeater Group was switched back on 15th October 2020.
Reports welcome.

You can find more information at http://gb3nb.org.uk/wp/our-repeaters/gb7nb/

Whilst the repeater was off air its software was updated to pi-star, you can find the new dashboard at

Morse Classes HAVE started.

Morse sweat

.
Local Morse classes that stopped over the summer have again started.
Chris G4CCX carried on stalwartly all through the summer. Hopefully you will all support the classes again this winter. Some advanced students really should be making QSOs on the air now on a regular basis and I know that this is happening but it should be occuring on a regular daily basis. My head copy class is now a QSO in the form of a ragchew on 80m and Phil G4LPP is a regular on that one. A few more would be welcome too!
.

.
Jim had three in his class this week, John G4PFZ, David M0WEL and 2E0FHF. Looks like those from last year have not joined yet or decided not to take part.Time will tell!

25wpm CW report for Tuesday 13th Oct 2020

Another fine piece of revision for the 25wpm CW group on the GB3NB repeater at 8pm on Tuesday evening.

We covered abbreviations and sample QSO texts, all sent at 25wpm, and gradually getting the team familiar with listening and reading as a head copy. The more time you can spend either having QSOs or just receiving and not writing it down, but getting used to the idea of picking out the odd word here and there, the better CW will be for you.

It suddenly happens that Morse is something you can monitor in the background and still capture the sense of the conversation. Anyone is welcome to join this group and don’t forget you can find practice files on the NARC website …

http://www.norfolkamateurradio.org/index.php/beginners-cw/content

… this includes MP3 files and text files, so there is no excuse for not having opportunity to practice between our weekly sessions on the repeater.

We don't have a beginner's class now merely because we have NO new beginners. However there is some good news!

Friday evenings 2000 local time, Morse with Doctor Phil G4LPP

Phil's class got off to a good start with two students. Hopefully next week there will be more!

If you are interested, please email Phil and let him know. He will contact you and give you more details.

By the way, Phil is a GOOD cop, so you will be treated kindly!
.
Steve 2E0SZD is scratching around for reasons NOT to join! He has not found one as yet..........
.
The CWOPS CWT activity periods are becoming even more popular. The 1300 session this week produced no less than 8 of us taking part so Norfolk ARC is being well represented! Several are already in line for medals and the year still has more than two months to go!

Email me with input, queries, keys, paddles, classes and so on. Hopefully I can help or know a man that can!
