When it comes to evaluating signal reception in the world of shortwave radio, the SINPO code reigns supreme. This universally adopted format provides a comprehensive assessment of signal quality, aiding broadcasters in fine-tuning their transmissions for optimal reach. From signal strength to overall clarity, each component plays a crucial role in deciphering the effectiveness of radio transmissions. Let’s dive into the intricacies of the SINPO code and how it facilitates seamless communication between shortwave listeners and broadcasters.
There is a universally used format for evaluating signal reception, when submitting a signal report and QSL card request, called the SINPO code. It calls for 4 reception parameters to be logged and a final evaluation of overall reception made. SINPO, is an acronym for signal, interference, noise, propagation, and overall, is a code used to describe the quality of radio transmissions, especially in reception reports written by shortwave listeners (SWLs). Each letter of the code stands for a specific factor of the signal, and each item is graded on a 1 to 5 scale.
Understanding the SINPO Code in Shortwave Listening
So when a shortwave listener is submitting a reception report to a broadcaster, using the SINPO code will help the broadcaster assess the effectiveness of their transmission in reaching the target zone.
In addition to using the SINPO code it is also useful to provide the following information when submitting a signal report:
Date and time in UTC, frequency, receiving equipment (receiver, antenna, and antenna orientation if directional), program details including content (ie news, music, etc), a contact address or email, for the station response.
Most broadcasters will respond with a QSL card or letter confirming reception.
Garry stumbled upon an intriguing discovery during his online perusal: a fascinating blog post that sheds light on the enigmatic world of amateur radio activity. We’re thrilled to share this valuable information with you, sourced from EI7GL’s “A Diary of Amateur Radio Activity” Blogspot.
In the heart of Alaska lies the High-frequency Active Auroral Research Program (HAARP), a pioneering initiative delving into the mysteries of the ionosphere. HAARP boasts a formidable high-power, high-frequency (HF) transmitter designed explicitly for ionospheric studies. At its core lies a sophisticated array of 180 HF crossed-dipole antennas, capable of emitting a staggering 3.6 megawatts into the upper atmosphere and ionosphere. This advanced system allows for flexible transmission frequencies ranging from 2.7 to 10 MHz.
Exciting news awaits as the research team at HAARP announces upcoming tests scheduled from February 28th to March 3rd, 2024. During this period, the program will conduct a comprehensive research campaign, with operating frequencies meticulously detailed. While the precise transmit days and times remain contingent upon real-time ionospheric and geomagnetic conditions, the team has outlined a series of experiments slated for exploration.
These experiments encompass a diverse range of objectives, including the production of Extremely Low Frequency (ELF) and Very Low Frequency (VLF) emissions, along with investigations into the impact of ionospheric plasma waves on orbiting satellites.
The findings from these endeavors promise to deepen our understanding of ELF/VLF wave dynamics and pave the way for future explorations into satellite interactions within space plasma.
For enthusiasts keen on delving deeper into HAARP’s research initiatives, the program’s FAQ page provides invaluable insights. Additionally, numerous experiments will operate at frequencies aligned with the f0F2 frequency derived from Gakona ionograms. Those interested in contributing reception reports are encouraged to reach out to HAARP via the provided contact information.
For real-time updates on ionospheric conditions in Gakona, individuals can consult ionograms from the HAARP Diagnostic Suite. Furthermore, for a comprehensive understanding of HF propagation and ionogram analysis, Bootstrap Workbench offers a helpful video resource.
With these resources at our disposal, lets explore this fascinating world!!

Tecsun Radios Australia Invites You to Share Your best Radio Shack Memories.
In a world buzzing with digital noise, there’s a timeless charm to the crackle and hum of a shortwave radio. It’s more than just a hobby; it’s a journey through time and space, a solitary pursuit that connects us across vast distances. At Tecsun Radios Australia, we understand the magic of shortwave, and we want to celebrate it with you.
Shortwave radio may seem like a solitary hobby, but it has a unique power to bring people together. Whether you’re tuning in to distant broadcasts or chatting with fellow enthusiasts online, there’s a sense of camaraderie that transcends borders and time zones. It’s about more than just the technology; it’s about the memories we create and the connections we forge.
That’s why we’re excited to invite you to participate in our latest competition. We want to see your favourite radio shacks and radios, old and new, and hear the stories behind them.
Whether it’s a vintage set passed down through generations or the latest Tecsun PL 990x, we want to celebrate the rich tapestry of shortwave radio culture.
To enter, simply snap a photo of you holding your oldest radio! Tell us about the memories it holds, the places it’s taken you, and the people you’ve met along the way. We will also need your permission to share this across our social media, blog, and EDM (our email newsletter)
One lucky winner will receive a free copy of “Southern Signals” by Hugh Tranter – a fascinating exploration of Australia’s history through the lens of communication.
“Southern Signals” reminds us that communication has always been at the heart of human history. From sea-stained dispatches to data sent back from deep space, it’s a story of how we’ve bridged vast distances through war and peace, exploration and growth. It’s a reminder of the power of technology to shape our world and bring us closer together.
So dust off your old radios, fire up your new ones, and join us in celebrating the magic of shortwave radio. Together, let’s create new memories and honour the rich legacy of this timeless hobby. Share your photos, share your stories, and let’s keep the spirit of shortwave alive for generations to come.
Please note this competition runs till the end of March 2024.
To enter the competition simply send a photo of you with your oldest radio and send it via email to hello@tecsunradios.com.au we will reply once received!
Join the conversation on social media using the hashtag #TecsunRadioMemories. We can’t wait to see what treasures you uncover and the memories you share.
