History SA Women's Radio Club
Susan Smith ZS1SM    Radio ZS August 1971
Susan turned 17 on May 23, 1971, 10 days after passing her technical operators exam.  
She is in Matriculation class at Sans Souci Girls High Newlands (CT)
Father (Sid ZS1PF) helped her with her radio studies. She passed her Morse test and received her license 30 June 1971 Her interest was stimulated by 16 year old Rodney ZS6ALL, believed to be the yougest operator.
News of Susan's achievement and passion for the hobby saw her soon receive a letter from SAWRC President Diana Green ZS6GH, inviting her to join the ' SA Women's Radio Club.. ' which Susan did.. and when SAWRC needed a new ' Trophy's manager ' a few months later, she volunteered for the task... Following through on her belief/commitment quoted above... “Ham radio is a thing you can't do casually or half-heartedly – it is really fantastic.. “
Susan was SAWRC Trophy's manager for a fair period, but when family and work life needed more attention as well, a new trophy's manager was appointed by the SAWRC.

The Dutch Young Ladies Club (PI4YLC) guest at PI4RS
Since 2012, we have been active with a team under the call PI4YLC from various locations in the Netherlands. For example, we once started with a contest team at PI4TUE in Eindhoven, we did a field day set-up in Ell, we were guests at OMs and YLs' homes and there were activities at departments of the associations.
This time we visited: Radio Scouting! According to their website: “Radio Scouting is a group of enthusiastic scouts who are interested in technology and communication. Our group consists of a number of radio amateurs and youth members of various scouting associations.” And we noticed that enthusiasm!
The Dutch Young Ladies Club had been invited by Bas PD7BDN to his QTH in The Hague, and if corona had not thrown a spanner in the works, we would have held a real YL meet-with contest in March 2020. All preparations were done at the time, the posters were made, the promotion was put online... but we had to cancel it. Fortunately, Bas' invitation remained, which he reminded us of every now and then. After more than three years, the time had finally arrived on the weekend of October 7 and 8. 2023 - PI4YLC was a guest at PI4RS!
With a small group of YLs from different parts of the world we went to The Hague to participate in the Thracian Rose Club DX contest (see website). A 36-hour contest, where the aim is to make as many QSOs as possible in CW and SSB, mainly with TRC members. It turned out to be a quiet contest, but we had no less fun because of it. You can make progress in a shack like that! We also had two great extra YL operators: Alexandra and Vlinder. We made a total of 262 QSOs in CW and SSB.
When it turned out on Sunday morning that there was little to do in the TRC DX contest, we also decided to call CQ on the 40m band. We put our call on the air and made about 100 QSOs in a short time. It's also nice to draw attention to the Dutch Young Ladies Club again in this way.
During our radio activities we were technically supported by the OMs of PI4RS. Thank you Bas PD7BDN, Ronald PB7TT and Jaimy PD1DBL for your support in this. The food was also very good! We had of course brought something with us for coffee, but Esther, Bas' wife, had provided dinner. We felt very spoiled!
Thank you for the hospitality, the nice conversations, the conviviality and especially the warm welcome! We would love to come back to Radio Scouting in The Hague!

YL NTX Weekly Net Celebrates 8 years on-Air
Started  November 2015, our 8th anniversary has come and gone.  And for all the organizations and nets promoting women on the radio, the issue remains.  How do we promote and encourage more women to get on the air in order to increase our numbers in a male dominated hobby?  That's a hard question to answer.  So let's flip it and ask... What keeps you coming back to the net (or the bands) week after week and how do we use that to attract other women of like mindedness?   Is it friendship, inclusiveness, fun conversation, science nerdiness, weather spotting, traffic handling, etc?  Let us know.   KC5BOO Judy Cox  14 Nov 2023

Minority Radio Operators HAM RADIO WOMEN  
Did you know that, according to the ARRL, only 15% of American amateur radio operators are YL's?  Of that 15%, there is a minority of YL's who are active.  Of those who are active, many are content to remain at the technician level, which is fine.  But, the higher the license class, the fewer the YL's you're likely to find.  
Female amateur radio operators have a very long and distinguished history.  From the very beginning of ham radio, women have been a part of it.  And, if truth be told, YL's tend to have a natural inclination to operating a radio - Why do you suppose that it was the women who were the premiere telephone operators?  Over the years, guys struggled to learn Morse, but the girls tended to be adept at CW.  (Just sayin'!)
As amateurs, we are familiar with the international ham "73" which means "best regards".  But did you know that there is a female version of "73"?  It is used from YL to YL and I like to think it means a bit more that just "best regards".  I like to think it means, "You go, girl!"  
So for those of us female hams, you might notice we say "33' to each other.  It's an acknowledgement of our history and our YL tradition. Personally, I'd like to see more YL's who are active hams and use "33".

ALARA-meet Tasmania Nov 3– 6, 2023
We're just giving YLs a reminder about our ALARAmeet next month 3rd to
the 6th November.  We have a special call sign for our meet  - VI7ALARA.  
I will be using that call sign for our special sked on Sunday
5th November at 0000 UTC on our Echolink ALARA conference station.  Last
time we did this was in 2017 at our ALARAmeet in Cairns.  We had
checkins from five continents with 43 YLs checking in.  What a pile up
we had but thankfully I had a scribe to help me.  Same this time so that
she can write all the call signs in our log.
So, hopefully some of you will be able to join us on the day.

    Antonia Ferrín Moreiras

WOTRA (Women On The Radio Award)
The November 2023 edition is dedicated to three pioneering astronomers:
Antonia Ferrín, first Galician astrologer who contributed to astronomy with works on stellar observations by the Moon, double star measures and astrometric measures and in 1963 became the first Spanish woman to defend a thesis on astronomy.
 Henrietta Swan Leavitt, an American who discovered a way to accurately measure distances on an intergalactic scale, paving the way for modern astronomy to understand the structure and scale of the universe.
Vera Rubin, who was the first woman to use the instruments at the Palomar Observatory. Before this, women had no permission or authorization to easily access, and their observations were very important to demonstrate the existence of dark matter.
This diploma is only operated by YL's. So we encourage our colleagues to participate.
If you know any local or foreign radio fans who might be interested, let them know.
If any YL reads this and wants to participate as a grantor: ec1yl@yahoo.es

Hedy Lamarr and Frequency Hopping
Hedy Lamarr - November 9, 1914 – January 19, 2000
Hedy Lamarr, who was a Hollywood actress in the 1940s as well as an inventor who holds the patent for frequency hopping, which is used in wireless communications today like WiFi and Bluetooth.  She was inducted into the National Inventors Hall of Fame posthumously in 2014.
 Hedy Lamarr (movie actress) and George Antheil (composer and pianist) worked together to develop a wireless communication system that stopped enemies from jamming signals that controlled the Allies' torpedoes in WW11 .Their joint invention used a mechanism akin to piano player rolls to synchronize the progression between the 88 frequencies.  The invention was dubbed frequency hopping because the system caused radio waves from the transmitter and receiver to switch to a new frequency simultaneously.

What is Frequency Hopping?
Frequency hopping is the most basic version of a radio transmission technique known today as the spread-spectrum technique, which refers to any method that broadens a signal's frequency band. Radio stations typically broadcast on a single carrier frequency, making eavesdropping simple: you tune your radio to the correct frequency and receive the programming.
Frequency hopping  prevents transmission interception and decipherment by shifting the carrier frequency in a predetermined, usually pseudorandom manner—that is, in a way that appears random but is produced by a deterministic algorithm. The message can be picked up by a receiver hopping around in time with the transmitter,

Happy  94 Birthday  PT2TF-Therezinha  Nov 10, 2023
Terezinha Felix Cardoso, PT2TF is one of the oldest YL operators in Brazil and was a member of the 1st Brazilian women's radio amateurs DX-expedition to Ilha Comprida-SP, 1998 (yl.beam news-setter #86 sept 2020).
She has been a member of YLRL (USA) for 47 years
She achieved many awards, during a time, mid-80s and early 90s, when there was no help from computers and GPS. QSL's were hand written and sent by postal services. Some arrived without the country name and had to be found via the area code.   QRZ.com only started in 1992. No e-qsl or e-mail.  
 In 2008 she received the highest award that a radio amateur can receive in Brasil,  “La Comenda da Ordem do Mérito do Radioamador” from LABRE (Liga de Amadores Brasileiros de Radio Emissão.) An award that only 34 radio amateurs have received and only 3 women (PP5ASN - Alda Schlemm Niemeyer;  PY6EAS Edna Assunção Sanches;  & PT2TF-Therezinha Maria Abranches Felix Cardoso)  Terezinha says this achievement would not have been possible without the support of husband Walter, PT2TG, who was tirelessly at her side solving everything needed in the radio shack or with antennas.
PT2TF-Therezinha  was Award Manager, until December 2011, of BRYLA (Brazilian YL Award), she found it a wonderful way to encourage the hunting of YLs not only in Brazil, but also in the rest of the world.  She feels that a contact with a YL is similar to rare DXpedition, or a space station contact,  due to the shortage of operators (LOL)

She was recently interviewed by Martin Butera LU9EFO/PT2ZDX, the interview was published in CQ Amateur Radio in the September 2023 edition in English. Her picture appeared on the cover and the five page interview  tells about this lady amateur radio operator.  The same interview, also in English, appeared in Radio ZS Volume 76, No 8 August 2023. p 42-49)
The interview is too long to reproduce here but has several interesting anedotes, best read in the original. However, the quote below from the interview says much about this remarkable operator.
“Terezinha: Amateur radio has always enriched my soul and spirit. It's like it keeps you alive, it motivates you, the fact of having so many friends all over the world, bonds of friendship are formed that never end. It is something wonderful.”

YL Raisa R1BIG reports back from the Conference in Croatia   11 Oct 2023
 Istra Contest Conference is over. We were 8 YL-operators out of 150 participants. This ratio is greater than the number of female voices on air. What's the secret?
We Radio Amateurs don't often have the opportunity to see each other face to face. Last weekend the Istra Contest Conference took place. This is a young event in our radio world. In 2023, the meeting was held for the second time, and the number of participants was about 140 people. The purpose is to exchange experiences, communicate, and support young people in our hobby. The list of presentations was amazing in its diversity.
The young people made several very good presentations - they talked about their experience of participating in contests, gave advice on how to support them, and even one of the young people demonstrated his difficult path to a homemade amplifier. This is inspiring!  
I was also honoured to give a presentation about YLs on the air. It was an exciting experience, although it was not so easy for me to be in front of an audience and speak English.
The conference took place in a beautiful hotel, right on the shores of the Adriatic Sea. Nearby there are several beautiful and interesting places to visit - Porec, Rovinj, you can take a boat tour and see dolphins.
I was very glad to take part in this event and meet the wonderful people I met on the air before. Many thanks to the organizer (Davor 9A1UN, Mirko 9A6KX, Richard 9A1TT, Emir E77DX and others) for the invitation and for their work promoting the radio. We are united by our love for a hobby and the desire to do something to develop it.
We invite everyone to attend the Istra Contest Conference next year on October 3-6. Plan ahead. See you there!
Now look at the photos, and of course there will be several videos! https://www.facebook.com/photo/?fbid=742453481230354&set=pcb.742459787896390

YL/OM UFT competition suspended (French Union of Telegraphists)  
This competition was initiated several years ago by Evelyne F5RPB to give the bands a little boost, and to highlight the YL telegraph operators.
In recent years, the number of YLs active in telegraphy has decreased for various reasons, the age of the operators being one of the main factors.
Given the few reports received over the last two or three years, and after discussion with the YL concerned, the UFT board of directors decided to put this competition on hold.
The organization of such an event, the correction of the logs, the necessary publicity and the publication of the results, represent a certain amount of work that is no longer justified by the low participation rates.
We all hope to relaunch this mini contest in future years, if the number of telegraph operators justifies it. The discussions in the salons give us hope for a rebound in the practice of our art in the coming years, so hope is not lost.
88 and 73 to all.  F6EEQ   - October 12, 2023    https://www.uft.net/concours-yl-om-uft/

Some thoughts and possible answers to the interference question.

Someone said; "It all goes away with load shedding!" - Yes the neighbour might not have a battery operated radio...

Potential Answer

I assume that the Ham radio operator has very good equipment, operates legally and is licenced. Could it be that the radio of the neighbour gets over loaded with spurious products from the radio's intermodulation distortion from the mixer; that could interfere with the neighbour's radio reception?

He could add additional filtering before his radio receiver that could remove the strong signals that overloads the radio receiver. I would say, add a high pass filter because the Ham operator transmits at HF 28MHz and the neighbour is listening on VHF 106MHz.

My response was:-

Yes almost right. You are not far off it. Remember the ham has a beam pointing North. Over the garden wall... Right at the neighbours house. And then think about 'image rejection'.

Noise has little to do with this 'interference' complaint. 'Cheap' FM radio/lo-fi and overloaded front end. Remember FM radios are local oscillator on the lower frequency side. They cannot be on the high side as the local oscillator would be in the aircraft bands.

Later

First of all think about the 3rd harmonic of 28.2 MHz. Then think about a 'low cost' FM radio having poor image rejection - second channel. The intermediate frequency of 10.7 MHz, means that the image is 21.4 MHz away from 702's Pretoria transmitter on 106 MHz...

You might need to reread the question. The Radio Amateur is using a recently bought transceiver that complies with the regulations. A beam that also is professionally made with only 400 Watts of output.

10.7 MHz is a global standard for an FM broadcast radio.

{--}

If you have a so called hi-fi tuner, you will probably have one with a plastic housing. No screening to speak of whatsoever.

Most Radio Amateurs will tell you to have a high-pass filter inserted in the antenna coax. To suppress the HF transmission. This will be of little use as the signal (Now around at Volts/metre) will bypass the filter and impact the tuner's front end directly. (screening of the receiver)

I picked 28.2 as an example frequency because I could remember 702 from the Pretoria transmitter is on 106 MHz. So the 'image frequency' would be 106 - 21.4. That is 84.6 MHz. The third harmonic of 28.2 MHz. This example also applies to the fifth harmonic. Which works out to be 16.92 MHz and is well out of band. So unlikely to be an issue! But the fourth harmonic would be 21.15 MHz. Another possibility. These harmonics would not be from the amateur's transceiver. But would be generated by the 'front end' circuits in the radio receiver. All of this can be summarised as a 'failing of the receiver'.

On this weekend I tried my phone's VHF FM radio. When I scanned the band, it found 47 radio stations here in Roodekrans! So the potential for interference is high. Also - as can be seen by the cartoon - the Radio Amateur will get the blame.

So whilst the radio receiver is technically at fault, try explaining that to your neighbour!

The radio amateur should first of all have a LOG of all his transmissions. So that he can refute claims of interference by referring to his LOG's time and date and frequency.

Secondly he should not be transmitting a full 400 Watts into a beam antenna. Especially on 10 Metres. When the band 'opens', the power level can be reduced to below 50 Watts or even 10 Watts.

Thirdly the radio amateur should offer to assist in solving the 'issue' with his neighbour. With a proviso that he doesn't spend money or a great amount of time. Some 'issues' could take some solving!

One solution that occurred to me was that the coax down lead to the radio receiver might be picking up more energy at HF than the front end could handle. Therefore a "Braid-Breaker" might resolve the 'issue'. So some experimentation would be needed. After all a recent anecdote had a plasma television wiping out HF for a nearby amateur! The coax to the roof antenna was resonant at 40 metres!

 

From a very old QST magazine.

An 'Interference Question' for Enhancing Thought Processing

This question was triggered by a couple of 'issues' I experienced some years ago. We no longer call them 'problems'. But INTERFERENCE is a huge issue and increasing in trouble level every day!

This is in no way an exam question as it is not a multiple choice answer.

I would like you to think about the 'mechanism' of this interference question.

A Radio Amateur in Gauteng has an H.F. transceiver putting out 400 Watts and a beam antenna pointing north towards Zimbabwe.

His neighbour next to his property is to his north and is listening to 702 on VHF FM on 106 MHz.

The ham has a sked with his friend in Zimbabwe on 10 metres. They have chosen to use 28.200 MHz.

After a few minutes of transmitting, his neighbour shouts at him over the fence. "You are wiping out my 702!"

He ignores him and they switch to narrowband FM on 28.2MHz. (Check the IARU Region 1 Band plan.)

The neighbour now goes to his garage and gets a loudhailer. Shouting "Now I can hear you plain as day!"

[There are various points here that should give you pause for thought.]

 

Questions

1. Explain the mechanism using simple maths and the knowledge from previous lessons.

2. Who is at fault? Or What is at fault?

3. What should the Radio Amateur do?

This is the HF Region 1 'bandplan'. Remember it is only a plan or recommendation.

So your decisions as to who is at fault, may or may not be 'legal'.

[I didn't intend for this to complicate the question.]

The 'thinking' about the process of interference is what I am after. Enjoy the puzzle.

Don't just go to the following pages. Understand the question first. Try and work out the means of the interference to the FM VHF radio.

YL Raisa to promote Ham Radio in Croatia

Hamradio not only for men - by R1BG/OH7BG and VO1BIG "YL Raisa"
YL Raisa is feeling excited. 20 Sept 2023:
It's time to make waves from beautiful Croatia.
I will be happy to greet and meet you PERSONALLY there.
Yes! It's not just another online Event - it is a face-to-face rendezvous! 🤩
We need to see fellow radio enthusiasts eye to eye and ignite the passion for ham radio among the youth and encourage more women to join Ham Radio.
Therefore, I gladly accepted the invitation of a 9A1P team to this event.
My journey to Istra will be difficult (there are no direct flights between Russia and Europe at the moment). But I am glad to have the opportunity, as one of the speakers, to talk about my path, positive five-year experience in our hobby and also to do everything possible to popularize Amateur Radio at this conference offline, and also online after it.

The Scientific Magic of Total Solar Eclipses
Throughout the millennia, total solar eclipses have instilled fear in some people while inspiring others, as the Sun’s wispy corona reveals itself in fleeting moments The recognition that the Sun’s corona is the extension of the solar atmosphere into space, together with magnetic fields on the solar surface, is less than a century old.

Thought this was of interest!! 33, Anne ~ WB1ARU F/w - McKenzie Denton (KO4GLN):
HamSCI: Where Science Meets HAM Radio:
HamSCI, short for Ham Radio Science Citizen Investigation, is on a mission to bring together amateur radio operators, scientists, and researchers.
Together, we'll delve into the effects of solar eclipses on radio communications.
It's all about expanding scientific knowledge and nurturing a sense of community among radio enthusiasts. Engage in the Solar Eclipse QSO Party by making radio contacts during the solar eclipse and entering your QSOs into a contest log.
Familiarize yourself with the Solar Eclipse QP contest rules, propagation measurement techniques, and data reporting. Remember, every observation counts,

HamSCI Solar Eclipse QSO Party October 14, 2023
FoEIS (Festivals of Eclipse Ionospheric Science)
Inviting all amateur radio enthusiasts, scientists, and the general public to participate in the HamSCI Festivals of Eclipse Ionospheric Science.
These are public events organized by the HamSCI (Ham Radio Science Citizen Investigation) organization to coincide with solar eclipses.
Participants will use a myriad of radios and antenna configurations to make measurements of the ionosphere and observe how it changes as the eclipse passes overhead.
They also use the occasion to promote science education and outreach, particularly in the fields of radio communication and space weather.
For more information, please visit: https://hamsci.org/

Nathaniel Frissell from The University of Scranton has invited amateur radio operators to participate in “Solar Eclipse QSO Parties.” The operators will attempt to make radio contacts with as many other operators as possible in different locations. This endeavor aims to observe how the ionosphere, an electrically charged region in our upper atmosphere that aids long-distance radio communications, changes during the eclipses. Previous experiments have demonstrated that solar eclipses can significantly impact the electron content of the ionosphere, affecting the behavior of radio waves.

The West Rand Ladies Field Day March 11-12, 2023
by Veronica ZR6TVK and Jack Kotzé, ZS6JJK
For the first leg of the 2023 SARL (South African Radio League) Field Day, the West Rand ARC (WRARC) decided to do something different (also lovingly known as the Woesrand! Ed.) A first for our club! A Young Ladies operating team with the Old Men providing technical support. We decided that an all YL operating team was a fitting plan to celebrate International Women’s Day. What a successful weekend it was, filled with QSOs from every division in South Africa and a couple of QSOs from the SADC Region. To every person that contacted us and wished us well, thank you. Your support is immensely appreciated. The ladies had a wonderful time with lots of giggles and jokes all around.
The WRARC Contest Team operated from the Baptist Church grounds on the mountain situated in Roodekrans, Roodepoort. The team met on Friday night to start setting up and of course enjoyed a braai (BBQ), a few members camped at the grounds. Thanks to our awesome technical team for setting up a perfect field station.
On Saturday morning the ladies were ready and waiting by 09:45 CAT to start calling and getting the Field Day Contest on the go. We had 5 YL operators - Alyscia le Roux, ZS6ALY; Beverley Van Tonder, ZR6BVT; Dienie Schnetler, ZS6DNI; Karin Andrew, ZS6MMA and Veronica Kotzé, ZR6TVK. We alternated during the contest and worked 10, 15, 20, 40 and 80 m bands throughout Saturday and Sunday.
Saturday night was spent enjoying each other’s company around the braai. A special mention must be made of Phillip, ZS6PVT and Beverley, ZR6BVT, they made the most amazing vetkoek!
On Saturday night around 22:30 CAT a freak wind came up and we had to run around to secure tables and tents, etc. Some antennae had to be lowered for safety.
It was wonderful to have a few of our RAE students visit. I could see the excitement in their eyes. I am sure they will be attending the next Field Day as operators.
All in all, this was a very successful Field Day Weekend for the WRARC team. I could see our “Technical Support Team” were itching to get on the radio and make a few QSO’s.
Thank you, guys, for the support and effort you made to give us the opportunity to enjoy this weekend.

 

A word from the OM Support team - Vaughn le Roux, ZS6VLR; Phillip van Tonder, ZS6PVT; Danie Schnetler, ZS6DPS; Glen Andrew, ZS6GGA and Jack Kotze, ZS6JJK.

“Yip, we were green with envy as we were banned from touching a mic and we didn’t dare try. Lucky for us, the (not so) Young Ladies were not too demanding except when it came to the antennas. They wanted to operate on all the bands, not only 80, 40 and 20 m!
While we waited to be called to attend to a technical problem we chatted about radio, load shedding (electrical power cuts) and potholes. We complained about work and our neighbours’ noise making devices. Some prepared food and others enjoyed refreshments. Some moaned about the forbidden mic but altogether a splendid weekend with good company, good food and lots of laughs.” The moral of the story. Field Day is a grand way to enjoy a weekend with your radio family!

 

Note how difficult the OMs found the day! (LOL) (Vetkoek is a traditional South African fried dough often stuffed with a sweet or savory filling.)

Japan YL Booth at JARL Ham Fair 2023, August 19 - 20
many people came to our JLRS (Japan Ladies Radio Society) booth. I would like to thank you for the opportunity to have fun talking with the people who visited us, including the 1st Eyeball QSO. We are also happy to have many beginner female hams visit us. We look forward to working with you in the future as well. Let's enjoy the radio!
We operated the JLRS corporate station "JA1YWM" from the venue using a handy-radio. Thank you very much to everyone who communicated with us. All the QSL cards we prepared have been issued, so we will hand them over to you . We will deliver to the stations that could not be reached via the bureau.
"JA1YWM" will be operated as a HAMttee member station from now on in Kiyosu City, Aichi Prefecture (JCC: 2035) , so please keep in touch with us.

Editor: Seems an appropriate event for Halloween?
AUSTRALIAN HAMS OFFER A QSO WITH A 'VAMPIRE'
VK2VMP HMAS Vampire - Australian National Maritime Museum
A team of amateurs, led by Colin VK2JCC, has set up shop in the radio room aboard HMAS Vampire. “HMAS” stands for His Majesty’s Australian Ship, and the Vampire is located at the Australian National Maritime Museum in Sydney. The radio room is part of the museum, and thus open for visitors to learn about the importance of radio communications, both in wartime and in peace.
The Vampire team uses the callsign Victor Kilo Two Victor Mike Papa, VK2VMP. (VMP = Vampire) If you have never worked a warship, now is a good time to start!
So far, eight amateurs are on the roster to keep Vampire on the air, using CW and Sideband on 20 and 40 metres, and the station is now a permanent fixture on the ship.
So, listen out for HMAS Vampire in Sydney, Australia. And check VK2VMP on qrz.com.

PS: Q - What does “vampire vampire vampire” mean in the navy?
A - NATO code-word for a hostile anti-ship cruise missile.
