Attention all amateur radio operators interested in transmitting WSPR beacons using a Raspberry Pi: A new, very much improved, version of WsprryPi software has just been released by AA0NT. WsprryPi features a web GUI as well as command line control options. #wspr #amateurradio https://github.com/lbussy/WsprryPi

Keep your nose to the grindstone...and your transistors. Initial test of the QRP Labs QMX+ for extended use as a WSPR beacon = flying colors

I got some questions on tiktok about what data rates the weak signal #hamradio #amatuerRadio modes like #wspr and #ft8 support. So I made this video in case it is interesting. Keep in mind my audience is people that are not skilled radio operators, consters, or even licensed users.

If you’re a guy intrigued by the world of amateur radio but haven’t yet taken the plunge to get licensed, there’s a powerful tool that can ignite your passion and deepen your understanding: WSJT-X. This software suite, developed by Nobel Laureate Dr. Joe Taylor (K1JT), is revolutionizing the way amateur radio enthusiasts communicate, especially under weak-signal conditions.

What Is WSJT-X?

WSJT-X stands for “Weak Signal Joe Taylor – eXtended.” It’s a free, open-source software designed for weak-signal digital communication by amateur radio. The suite includes various modes like FT8, FT4, JT65, and WSPR, each optimized for different types of radio-wave propagation.

Why Should You Care About WSJT-X?

Even without a license, WSJT-X offers a window into the amateur radio world. You can monitor signals, understand propagation patterns, and get a feel for the community. It’s like being a fly on the wall in a global conversation, offering insights that can be invaluable when you decide to pursue your license.

Getting Started with WSJT-X

Download and Install: Visit the official WSJT-X website to download the software compatible with your operating system.WSJT+2WSJT+2WSJT+2
Set Up Your Hardware: While transmitting requires a license, receiving doesn’t. You can start by connecting a Software Defined Radio (SDR) like the RTL-SDR to your computer. This setup allows you to receive signals and observe the digital modes in action.
Configure the Software: Input your location details and set up the audio input from your SDR. Ensure your computer’s clock is synchronized accurately, as digital modes like FT8 are time-sensitive.
Start Listening: Once set up, you can start monitoring various bands. You’ll see call signs, signal reports, and other data scrolling across your screen, providing a real-time look at global communications.

Understanding Digital Modes

WSJT-X supports several digital modes, each with unique characteristics:

FT8: The most popular mode, designed for quick and efficient communication under weak signal conditions.
FT4: Faster than FT8, suitable for contesting and rapid exchanges.
JT65 and JT9: Older modes, still used for specific applications like moonbounce communications.
WSPR: Stands for “Weak Signal Propagation Reporter,” used for testing propagation paths with low-power transmissions.

Learning from the Community

Engaging with the amateur radio community can enhance your learning experience. Platforms like Reddit’s r/amateurradio offer discussions, advice, and shared experiences from both seasoned operators and newcomers. Additionally, websites like HamStudy.org provide study tools and resources to help you prepare for your license exam.

Monitoring Propagation with PSK Reporter

PSK Reporter is a valuable tool that collects and displays reception reports from around the world. By monitoring this data, you can observe real-time propagation conditions and understand how signals travel over various frequencies and distances.

Exploring Further with YouTube Tutorials

Visual learners can benefit from comprehensive tutorials available on YouTube. For instance, the WSJT-X FT8 Tutorial Master Class offers an in-depth look at setting up and operating WSJT-X, providing step-by-step guidance for beginners.

Conclusion

WSJT-X serves as a gateway into the fascinating world of amateur radio. By observing and understanding digital communications, you can build a solid foundation that will serve you well when you decide to pursue your license. The software offers a hands-on experience that complements theoretical study, making your learning journey both practical and engaging.

#WSPR running on the FT-847, 1W, via DigiRig. Let's see...

Next, testing / building cable for Kenwood - I bought the cables pre-made but have a suspicion it won't work and I will need to build another GX16 cable, this time with Kenwood pins.

While I'm at it, I should get the C-5800 cable done, and another cable for the FT-480R.

Running #WSPR with 1W on 20m.

Наконец добрался до WSPR. Очень интересный инструмент проверки и изучения прохождения, тестирования антенн и тд. Вчерашний эксперимент на 2Вт показал, что этого много и мой антенный комплекс в этом положении отлично работает на линии Рим-Лондон.

Но это было бы бесполезно без принимающих. И для любителей серверов хорошая новость: не нужно держать графику. Достаточно поставить rtl-sdr и запустить rtlsdr_wsprd. Всё, вы - один из тех, кто помогает изучать прохождение радиоволн.

#hamradio #wspr

Flying to Hotlanta today for a conference. Decided not to bring a radio and to just tune around on websdr. If I have any free time, priorities will be learning about WSPR, WSJT-X & Olivia and desoldering SMD IC chips.

I’m receiving WSPR signals but my tx is not being spotted. Got a qrz-unknown callsign on a boat just north of Dominican Republic on the tropic of cancer yesterday!

Random #wspr monitoring question.

I have an rtlsdr monitoring 8 bands by running rtl_wsprd for a set period of time, killing it, then relaunching on a different band.

Because 8 bands fit neatly into 24 hours, without prior planning, I'd end up monitoring the same band at the same time each day, something I'd like to avoid.

Every time I relaunch I lose at least a potential monitoring cycle, generally two.

Would you monitor for 25 hours, under an hour, over an hour, or something else per band?

Fired up the WSPR beacon so my dad can show something to some students at a demo somewhere. He's big on teaching Things And Stuff!

I just like having the GPS viewer up in a terminal when the QMX+ is running. It's neat!

#hamradio #WSPR

@DJ5CW 🤔 Interesting observation!

I’ve set the QMX up to transmit every 12 minutes, starting with minute 2. Should give :02, :14, :26, :38, :50. Nice and evenly distributed.
Not sure what the 10 % or 20 % duty cycle in WSJT-X and potentially band hopping might do to the statistics.
#hamradio #wspr #wsjt

When watching 10 minute frames of WSPR on 30m, I often have the impression that the 5th two minute slot (starting in the 8th minute) is particularly busy, while the 4th (6th minute) is pretty poorly populated. A quick analysis of all WSPR spots received at SO5CW since August 2024 confirms this:

0: 111k
2: 101k
4: 96k
6: 88k
8: 133k

Wonder if that's some poorly implemented random function in WSJT-X?

After trying to manually correlate propagation events I saw on my #QRSS / #WSPR grabber with the solar flux data from the #NOAA #SpaceWeather Prediction Center for a while, I wrote a few lines of Perl that simply plot the current data below the grabber output... https://fkurz.net/ham/qrss/30m-24h #hamradio #propagation

@Josefius @qrplabs

It’s in a box. I need to build it before it gets warm so I can do #pota

And i want a #wspr station back on the air.

@VE7WYC

Slick! I need to set up my #WSPR listening station again.

My WSPR receiver picked up quite a few signals from the US/VE West coast area yesterday that I usually don't see (N6RY, VE7AV, ...), along the grayline (15:10..15:40 UTC - ignore the grayline you see on the screenshot, it's the current one). Today I will keep an eye on my WSPR and see if I can raise some DX on 30m CW at the same time. #hamradio #propagation #wspr

Warto było się pobiedzić. Niemal natychmiast Andrzej wśród stacji polskich i zagranicznych do ok. 2000km na 80m odebrał... HS0ZOB, ponad 8000km! 😮

#SierraEcho naprawdę się wkręcił w #WSPR. To LAJW zaczęło nawet przypominać stare live'y sprzed 2-3 lat, kiedy Andrzej dużo majsterkował, odkrywał #krótkofalarstwo 🥺

Ale czar prysł jak ktoś rzucił hasło "AKTORKI" 🥸

Wtedy zrobił ankietę.

Zamknął ją na końcu LAJW, z wynikiem 59% za aktorkami. Będą w sobotę.
