Daily DXER ham radio news

The completed 20 meter loop antenna.

A few days ago, SWLing Post contributor, Robert Gulley (AK3Q), pointed me to an excellent website by Harry Lythall (SM0VPO) which is chock-full of various homebrew radio projects. In particular, we both were impressed with Harryâ€™s 20 Meter Loop Antenna–itâ€™s such a simple projectt and requires no special order components. In fact, all of the components (save, perhaps, the antenna connector) can be purchased at a DIY store.

I reached out to Harry and he has kindly allowed me to republish this project as a guest post:

20m Loop Antenna

by Harry Lythall — SM0VPO

Introduction

I recently saw that my 80m (3.5MHz) loop (or frame) antenna has been really popular, and that there are loads of other radio amateurs who have taken my design and â€œran with itâ€ to produce variations that all have some great improvement. There have been many in-depth tests and simulations, all with exceedingly good results and reports. This is exactly what I am aiming for with my homepages — free information for all and mmy designs being improved upon. That way we all win

One small point all variations have in common is the need for an expensive tuning capacitor and a very restricted RF power level. Of course, you can throw money at the problem, but for me this hurts. I got to thinking that there must be a way of adjusting the design a little and finding another technique to tune the antenna, and to make the best use of the little radio transceiver I have in Sweden, given the limited space.

My limited space apartment.

As you can see there is not much opportunity for grand antennas. And to add to this, the equipment I have in Sweden is also limited to a single 5-Watt unit.

My limited equipment — only 5-Watts.

The Design Thoughts

Today I have no area of land to use for antennas. I have a glassed-in balcony on the 4th floor of an apartment block. I really like the 20m (14MHz) band so I will concentrate on that. I am not really interested in the CW end of the band, except perhaps 14.070MHz for the digimodes. So my requirements are:

As efficient as possible (useable)
Small size, also portable so I can use it for field use
No expensive components, everything available locally
No TVI, QRM or interference to stereos or computer sound
Total price less than $2

The antenna I have created is based on my original 3.5MHz loop (or frame) antenna. This time I built it out of scrap components. I cadged (tiggade) some plastic conduit tubes from an electrical contractor at work. The same guy also gave me the remnants of a roll of 2.5mm C.S.A. multi-strand mains cable. That was all I needed.In my junkbox I found no tuning capacitors, but WAIT!! Why do I need to tune the antenna? Once it is tuned I should not need to tune it again, just set the centre-frequency to 14.175MHz. If I can get the Q-factor to around 100 then my useable 3dB bandwidth should be more than 150kHz. That will give me 14.10MHz to 14.25MHz.

Ok, I need a 1-off, preset tuning capacitor. Why not use a Gimmik Capacitor? Just twist two bits of wire together and cut it short to get the resonant frequency I want. So I need to get the coil wound so that there is sufficient cable length and self capacitance to give a resonance of about 14.5MHz without any extra capacitance what-so-ever. That means I need just a few pf. That sounds like a good plan.

Construction

The 15mm Diameter plastic tube I â€œaquiredâ€ were 80cm long. After much trial and error I found that exactly 3 turns, with 2.5cm spacing, gives about 14.9MHz self resonance. The wire support holes are exactly 4cm spaced, beginning 1cm from the end of each tube. The two tubes are fixed into a and X using zip-straps (tie-wraps, buntband). The feed loop is 1/2 turn.

Note the size and position of the feed loop. Also the Gimmik capacitor.

One problem I had with the original loop antenna was that of RF coming back down the cable braid. Using on old FT-101ZD it was possible to feel the RF on the microphone with your lips. The cure for this is to use a balanced feed and at least 5m of RF cable.

I robbed the ferrite ring for the balun from an old ATX computer PSU and made a triflar wound torroidal transformer. That is to say, twist together three lengths of 1mm x 7-strand insulated hookup wire together. Use this to make a 7-turn coil and connect the three coils in series, with four connections. Feed connections (numbered in the picture below) 1 and 3 are connected to to the antenna feed loop. Connect the coaxial cable braid to connection 2, and the coax centre to connection 4. My balun is self-supported on the connection leads.

The 1:1 Balun I used.

The coaxial feed cable was found to affect the resonance slightly, so I fed that through an extra bit of tube to make it stay in one place. It works fine.

Feeder cable secured in the support tube.

Testing

Testing is very easy. I used my GDO-2 to check the middle-turn of the loop for a dip. Twist the two tails together to form the Gimmik capacitor and adjust the length of the twist until the centre-frequency is 14.175MHz. With the GDO you can get it within about 100kHz to 200kHz, but then you can check the VSWR using your HF radio. You can also sweep the band for maximum noise and get a very close approximation.

The Gimmick capacitor.

The centre frequency of my 20m Loop antenna is 14.175MHz, and the VSWR is better than 1.05:1 (I can hardly see any movement on my meter). The Q-factor is somewhere approaching 100. The useable bandwidth is just a little narrower than I would have wished, but the antenna certainly works well and meets all the other criteria. But the slightly less useable bandwidth criterion is at the expense of better performance, and it still allows me to use 14.070MHz, although it is a little quieter down there.

The completed antenna.

Conclusion

No-matter how you play with the figures, the best indoor antenna cannot replace a full-size dipole antenna. But the indoor antenna can give some extra features, such as just reaching out your arm and trimming a little, which you cannot do with a long-wire antenna up a tree out in the garden, especially when it is raining.

This antenna gets me on the air on 14MHz, and it has a useable frequency range. The VSWR is almost perfect at the centre-frequency, and this time I donâ€™t burn my lips on the microphone (not that I am likely to do so with just 5-Watts of power). The design uses no expensive components, in fact the only item I bought was the block-connector for the balun. That cost me US$1.50 for a pair of 12-contact screw-terminals. The construction is ridiculously simple and easy to build.

On the air I can hear traffic on 14.070 digimodes, and from 14.130 to 14.220MHz I have a near-perfect VSWR aqnd good clear reception of SSB. I can also rotate the antenna to cut out rubbish, and most of all, using the Gimmik capacitor I donâ€™t need to re-tune it: it seems temperatore-stable. The weight is less than 500g and when I poke it out of the balcony window the reception improves, the VSWR does not change, and I can make myself heard among the big boys.

I hope that you have some fun building and using this antenna. If you have any ideas for further improving it then please use my forum.

Donâ€™t forget to visit my messageboard if you have any questions about this or any other project. I always look forward to receiving feedback, positive or negative.

Very best regards from Harry Lythall

Many thanks, Harry, for sharing this excellent project on the SWLing Post!

Post Readers: be sure to check out Harryâ€™s website which is loaded with radio projects of all stripes. Youâ€™ll easily spend a few hours digging through his tutorials and downloads. Harry also maintains an alternate mirror server located here.

Side note: Iâ€™m impressed with the fact that the main SM0VPO website is actually hosted on a bedside Raspberry Pi computer (running the Linux-based Lighttp server). Very cool!

Daily DXER ham radio news

â€‹
May 25, 2018 — R. Fisher KG5SJO
Are you looking for something to keep those busy bodies engaged on summer break?
How about something that is almost free, combines the concepts of Science, Technology, Engineering, and Math and is so practical and fun they wonâ€™t even realize theyâ€™re learning.
If so, follow along, because unless you know a Ham Radio Operator, youâ€™ve probably never even heard of it.
So letâ€™s dig in and see why Ham Radio is one of the Greatest STEM Opportunities for kids youâ€™ve probably never even heard about.
What Is Ham Radio?
Ham Radio, or as its officially titled, the Amateur Radio Service, is a license issued by the Federal Communications Commission (FCC), which allows U.S. citizens privileges to operate within designated frequency bands reserved for Ham Radio Operators.
In other words, the license allows you to use specific radio frequencies to communicate with other Ham Radio Operators, experiment with technology, design software, send emails, tinker with WIFI, control remote controlled vehicles, talk to the International Space Station, and a whole host of other things!
I Know, Exciting, right?
How Is Ham Radio A Great STEM Opportunity?
Ham Radio is all about experimenting and learning. Here are just a couple of examples:
After obtaining my license, one of the first things I did was build an antenna. Building an antenna greatly increases your ability to hear and contact other Ham Radio Operators and involves Science, Technology, Engineering, and Math, and itâ€™s not a complicated process.
Recently, I began working on building and setting up an Allstar Link. This involves a Computer or Raspberry Pi, Electronics, and a small amount of coding. It gives me the Opportunity to talk to other Ham Radio Operators anywhere in the World by merging a Radio with the Internet.
There are so many things that can be done with a Ham Radio License, the possibilities are endless.
Ham Radio provides opportunities for you to share STEM with your kids, family, school, or the community in which you live.
How Do You Get A Ham Radio License?
In the U.S., there are three Amateur Radio licensing levels, Technician, General, and Extra. Each level allows the Operator more frequency privileges.
Getting licensed is as simple as passing a 35 question multiple choice knowledge exam.
And the best part, there are no age restrictions for obtaining a license, and there are tons of exam locations for you to take your little puddle jumpers.
The American Radio Relay League has created a database for locating exam sessions in your area, which you can find here.
The 35 questions used for the exam are drawn from a pool of questions and are available for study.
The American Radio Relay League has an online question pool study section that is available free of charge and can be found here.
Additionally, you can purchase any of the many books available, below are a few books that I have used as I prepared for my Technician Exam.
What If My Kids Are To Little To Take The Exam?
Donâ€™t let that slow you down, if you think your kids are to little to take the exam or comprehend the material, you have another option known as third party traffic.
This option allows you to take the exam and still introduce your little ones to the world of Ham Radio.
Once you are a licensed Operator, your kids can communicate with you at their side. This is a great way to get people comfortable with using a Radio and understanding the concepts.
This Sounds Expensive,

In episode 21 of the TX Factor show Bob McCreadie G0FGX and Mike Marsh G1IAR discuss the linear (SSB/CW) amateur radio satellites and give a demonstration with the CAMSAT XW-2F satellite.

They also review the new Icom IC-7610 transceiver, and look at programming your SDR handie and running a SharkRF openSPOT digital radio IP gateway.

As always, in their free-to-enter draw, thereâ€™s a chance to win two great amateur radio-related items — a Prism dust cover for yourr rig, and a copy of the book â€œAmsats and HamSatsâ€.

Bob and Mike discuss satellites near the start of the show and towards the end at 48:08 they give a live demonstration of the CAMSAT XW-2F SSB transponder satellite.

EnduroSat One

Bulgariaâ€™s first CubeSat, EnduroSat One, was launched to the International Space Station on the cargo resupply OA-9 mission on May 21, 2018 from the Mid-Atlantic Regional Spaceport in Virginia, USA. On May 24 the Cygnus capsule docked to the Station and the satellite was taken onboard the ISS.

The satellite will be deployed from the ISS in the coming weeks.

The mission aims to popularize the Radio Amateur activities in Bulgaria and it will include cooperation with Bulgarian Federation of Radio Amateurs (BFRA), including workshops and additional educational activities.

The spacecraft has been completely built in Bulgaria. This first educational mission aims to inspire young Bulgarians and give them the chance to participate in a real space program!

The Space Challenges and EnduroSat teams have invested considerable resources, time and effort in preparing the Bulgarian CubeSat. In order to support the Radio Amateur community, the satellite emits in frequencies which are readily available for receiving by anyone with basic communication skills and radio equipment.

It is hoped the mission will help more young Bulgarians learn the basics of satellite communications through practical exercises empowered by the orbiting satellite.

Radio amateurs from around the Globe will be able to listen to the satellite beacon and to receive telemetry data from the satellite on a regular basis. They will be able to connect to the satellite, receive detailed telemetry information and receive a confirmation from the satellite for every established connection which will serve as QSL card.

Beacon: 437.050 MHz CW and 9600 bps GMSK AX.25

Live demos are a highlight of the event, like making contact with a beach portable drone.

SEA-PAC, the Pacific Northwestâ€™s largest convention of independent ham radio operators, arrives at the Seaside Convention Center for the weekend of Friday, June 1, through Sunday, June 3.

Now entering its 36th year, the event features exhibits, seminars, a flea market and family entertainment. Itâ€™s also an annual opportunity for ham radio operators from around the region to gather and talk shop. And itâ€™s a chance for novices to learn from the pros and get a glimpse into the fascinating, communicative world of ham radio.

Far from an introverted bunch, independent operators enjoy meeting new people and experimenting with the latest trends in their field.

â€œReally, weâ€™re just a bunch of folks who like playing with radios,â€ SEA-PAC Chairman Delvin Bunton said.

Like many people who become interested in ham radio, Bunton caught the bug in his youth. A desire to travel the world without leaving home held great appeal, especially in the years before the cell phone age.

Legendary rock guitarist Joe Walsh, WB6ACU, of the Eagles is featured in a just-released set of ARRL audio and video public service announcements promoting Amateur Radio. ARRL will provide the 30- and 60-second PSAs to Public Information Officers (PIOs) to share with their Sectionâ€™s television and radio stations. The ARRL Media and Public Relations Department also will provide these announcement files directly to interested television and radio outlets. The announcements are available for downloading from the ARRL website for members to use in promoting Amateur Radio at club meetings and public presentations, such as ARRL Field Day June 23–24 (PSAs specifically for ARRL Field Day also aare available).

Walsh, who visited ARRL Headquarters last year for taping, wanted to deliver two main messages in his PSAs: get involved in Amateur Radio, and become a member of ARRL. The messages highlight the tremendous service that radio amateurs provide to communities, and convey how ARRL advocates on behalf of Amateur Radio on a wide range of legal and political issues.

An ARRL Life Member and long-time radio amateur, Walsh personally has been a strong supporter and advocate of ARRL and Amateur Radio, and his ham shack is just as impressive as his home recording studio. â€œI want to give back to the hobby that has given me so much enjoyment,â€ he said.

The setting for the PSAs was W1AW, which Walsh was especially eager to revisit. The occasion also offered him with an opportunity to see equipment heâ€™d donated to W1AW years earlier. Walshâ€™s past on-the-air forays on W1AW have always attracted enthusiastic pileups. While at W1AW, he spent some chatting with station manager Joe Carcia, NJ1Q, about the stationâ€™s operations. Walsh is a well-known collector of vintage Amateur Radio equipment.

Creating the videos were Media and Public Relations Assistant Michelle Patnode, KC1JTA; freelance videographer/photographer Chris Zajac, and former Media and Public Relations Manager Sean Kutzko, KX9X, who also recorded a tag line for ARRL Audio News with Walsh.

Tips for getting audio PSAs on the air are available on the â€œPlacing Audio PSAsâ€ web page.

On the fourth weekend of June each year, more than 35,000 radio amateurs (hams) gather with their clubs, groups or simply with friends to operate from remote locations.

Until recently, local ham radio clubs competed against one another to make as many contacts as possible under simulated emergency conditions. In the 2018 ARRL Field Day, however, a consortium of local clubs from Daytona Beach to St. Augustine will gather together under the banner â€œCQ Floridaâ€ to compete with as many as 35,000 ham radio operators around the country.

Members of the Flagler Palm Coast Amateur Radio Club, Daytona Beach Amateur Radio Association, St. Augustine Amateur Radio Society, Flagler Emergency Communications Association, American Legion Amateur Radio Club 5th District and Flagler County Assist REACT Team 4800 will participate in the national Amateur Radio Field Day exercise June 23–24. The exercise will last 24 hours, beginning at 2 p.m., at Hammock Community Center, 69 MalaCompra Road, Palm Coast.

Field Day is a picnic, a campout, practice for emergencies and an informal contest. During the event, many aspects of amateur radio come together to highlight its many roles. While some see the 24-hour experience as a contest, others will use the opportunity to practice their emergency response capabilities. The Field Day also provides an opportunity to demonstrate amateur radio to the organizations it could serve during an emergency, as well as the general public.

During the contest, ham radio operators simply contact as many other stations as possible and learn to operate the radio gear in abnormal situations and less than optimal conditions.

Hams are well-known for providing communications support in real disaster and post-disaster situations. Despite the development of very complex, modern communications systems — or maybe because they are so complex — ham radio has been called into action again and again to provide communications in crises when it really matters.

One radio amateur now onboard the International Space Station will be heading home on June 3, while another will take his place on the crew a few days later.

Flight Engineer Scott Tingle, KG5NZA, will join Expedition 55 Commander Anton Shkaplerov and Flight Engineer Norishige Kanai in returning to Earth on the Soyuz MS-07 spacecraft after 168 days on station. A few days later, another trio of space travelers — Alexander Gerst, KF5ONO, SSergey Prokopyev, and Serena AuÃ±Ã³n-Chancellor — will head to the ISS in a Soyuz MS-09 spacecraft.

In a traditional change-of-command ceremony on June 1, Shkaplerov will hand over command of the station to NASAâ€™s Drew Feustel, officially starting Expedition 56. In addition to Feustel, Ricky Arnold, KE5DAU, and Oleg Artemyev will remain on station.

This will be the â€œHorizonsâ€ mission for Gerst, of the European Space Agency, who will assume command of the ISS for the second half of his duty tour. Gerst, who first served on the ISS in 2014, likely will use the call sign DP0ISS for any Amateur Radio on the International Space Station (ARISS) activities.
