A Pileup? What It Is And How To Work One
Welcome to the chaotic, thrilling world of the HF pileup. Whether you are the one calling CQ from a park in Nebraska or the one hunting a rare DX station, success relies on rhythm, frequency management, and a deep understanding of human behavior.
Here is a proper look at how a pileup appears on a modern display, followed by a complete guide on how to survive it.

A “pileup” on shortwave amateur radio frequencies. The main station is at the low frequency, and stays put. The hunters spread out, above, and call on a single frequency somewhere in the calling window of frequencies (I.e., up five to ten).
Over my decades of working Morse code (CW on amateur radio), I have learned a few critical things about how to navigate the chaotic, thrilling world of the HF pileup. When a rare station or a Parks On The Air (POTA) activator goes on the air, dozens or even hundreds of operators might try to make contact at the exact same time. Working a pileup is an art that takes time to master. Whether you are the one calling CQ from a park in Nebraska or the one hunting a rare DX station, success relies on rhythm, frequency management, and a deep understanding of human behavior.
One of the most important strategies is to determine the operating style of the DX station, specifically discerning how that operator scans the pileup for the next station to work. With modern waterfall displays, that process is MUCH easier. As an example, I worked the Temotu DXpedition (H40RH) that had just started a few hours prior to my attempt. I broke through with only five calls into the pileup, and it took me a mere 60 seconds to call and get an answer. Of course, I first listened and watched the waterfall for about five minutes to get a hang of the operating style of H40RH. This was on 10 Meters where 28.026 MHz was the DX frequency. We callers spread out five to 15 kHz UP in frequency from the DX station because we never want to cover up the DX station with our own signals. Even with a long carrier of intentional interference visible on the waterfall, the visual aid of the SDR made the catch possible. Temotu was a new country for my DXCC, so I am incredibly pleased to have made the contact!
When You Are the Hunted (The Activator)
A Guide To Survive The Pileup
When you are the station that everyone wants in their logbook, you are the conductor of the orchestra. If the pileup senses hesitation, chaos ensues. You must dictate the pace, for both CW and SSB operations.
Controlling the Pileup on CW
Establish a Predictable Rhythm: Your CQ, your exchange, and your QRZ should follow a strict pattern. Consistency allows hunters to time their calls perfectly. If you change your cadence, the pileup gets messy.
Run Split for Large Piles: If the pileup merges into a single continuous drone, go split immediately. You might send “UP 1” to tell callers to transmit one kilohertz above your listening frequency. This spreads the callers out. Send your “UP” frequently enough that the self-appointed pileup police do not take over your transmit frequency. I suggest sending “UP” after each successful logged contact (QSO).
Own the Partials: If you only pull “NW7” out of the noise, send “NW7?”. Do not send “QRZ?” immediately. Stick to that partial call until that specific station finishes the exchange. If they fade out, clearly send “QRZ?” to reset the pile.
Adjust Speed to Control Volume: A slight speed increase (bumping up 3 to 5 WPM) will naturally thin the pileup down to the more experienced operators. Dropping your speed will invite the newer operators back in.
Receiver Management: Back off your RF gain and use a wider filter than you might expect (around 400 to 500 Hz). A filter that is too narrow will cause you to miss the operators who are smartly calling slightly off-frequency.
Controlling the Pileup on SSB
Command with Your Voice: Speak clearly and maintain a steady, authoritative tone. Avoid shouting. Just like in CW, a predictable rhythm helps callers know exactly when to key their microphones.
Use Standard Phonetics: Stick strictly to the standard NATO phonetic alphabet (Alpha, Bravo, Charlie). Cute or custom phonetics confuse operators who do not speak English as their first language.
Acknowledge and Isolate: When multiple voices blur together, listen for the last phonetic letter you can understand. If you hear “Sierra,” say “The station ending in Sierra, go ahead.” Ignore everyone else until that station completes the contact.

My POTA / Portable HF station (a low-power, or, QRP, station).
When You Are the Hunter (The Chaser)
When you are trying to break through a massive wall of sound, raw output power is secondary to timing and sharp observation.
Breaking the Pileup on CW
Listen First, Key Second: Before touching the paddle, listen to three or four complete exchanges. If the activator is working split, figure out their pattern. Are they tuning from the bottom up? Top down? Find where they listened last, and place your transmit frequency just above it.
Use XIT (The Golden Rule): Never perfectly zero-beat the DX station if others are calling. To the activator, three zero-beat stations merge into a single tone. Use your Transmitter Incremental Tuning (XIT) to shift your transmit frequency by 30 to 50 Hz. This slight difference in pitch makes your signal pop out of the receiver passband.
Time the Tail-End: Wait for the massive wall of sound to begin fading, and send your call exactly as the main group finishes. A perfectly timed tail-end call lets your suffix ring out in the clear.
Send Once: When the DX sends “QRZ?”, send your callsign exactly once and listen. Sending your call multiple times just causes interference and slows down the entire operation.
Follow Instructions: If the DX sends “NW7?”, and that is not you, keep your hand off the key. Transmitting over the station they are trying to work only prolongs the pileup for everyone.
Breaking the Pileup on SSB
Study the Cadence: Just like with Morse code, listen to the activator to find the rhythm. Wait for the exact moment the activator stops speaking before you key up.
Drop Your Call and Wait: Say your full callsign once using standard phonetics, then unkey and listen. If you are tail-ending, you might just drop the last two letters of your callsign precisely as the noise floor drops.
Adjust Your Pitch: If you have equalization controls on your radio, boost the mid-to-high frequencies on your microphone audio. A slightly punchy and higher-pitched voice will cut through the bass-heavy rumble of a dozen other stations calling at once.
Working a pileup tests your patience and your ear. Whether you are tapping out Morse code or speaking into a microphone, the operator who listens more than they transmit almost always makes the contact first.
Propagation and the Pile-Up
As many of you know, I was the space weather and radio propagation columnist in CQ Amateur Radio Magazine from 2001 through its demise. I strongly advocate for all HF radio operators to understand the basics of radio wave propagation on shortwave frequencies. There are a lot of myths and frankly, horrific theories on how radio waves propagate.
Understanding how the ionosphere refracts radio waves is a crucial tactical advantage. The behavior of a pile-up changes dramatically based on the frequency band you choose and the current mood of our sun.
The Sun Dictates the Rules
The ionosphere is charged by solar radiation. When solar activity is high, higher frequencies become usable for long distances.
Solar Flux Index: The SFI is a great indicator of overall ionization. A higher SFI means better conditions for the higher HF bands. When the SFI climbs, bands like 15, 12, and 10 meters open up globally.
Geomagnetic Storms: Measured by the K-index, these storms can disrupt communications entirely. A high K-index often absorbs signals crossing the polar regions. This can suddenly mute a massive European pile-up for North American operators.
Fading: The ionosphere is always shifting. Signals will constantly rise and fall in strength, which is known as QSB. A smart chaser listens for the rhythm of this fade and throws their callsign into the pile-up exactly when the band peaks for their specific location.
How Bands Shape the Pile-Up
Every amateur radio band has its own personality. The pile-ups you encounter will reflect these differences perfectly.
10, 12, and 15 Meters: These high bands are daytime frequencies that thrive on high solar activity. When 10 meters opens up, signals can be astonishingly loud with very low atmospheric noise. Pile-ups here can ignite suddenly and stretch very wide across the frequency spectrum.
20 Meters: This is the traditional workhorse band for global communication. Pile-ups on 20 meters are massive, sustained, and densely packed. You will often compete with high-power stations and massive beam antennas on this frequency day or night.
40 and 80 Meters: These low bands come alive at night. They are heavily affected by atmospheric noise and static crashes. Breaking a pile-up here requires an exceptionally well-tuned ear and the ability to pull faint CW tones or muffled voices out of a very high noise floor.
The Skip Zone Effect

The propagation of radio waves.
One of the most confusing aspects of a pile-up for a new operator is the skip zone. Radio waves bounce off the ionosphere and return to earth far away, which means they skip right over the geographic areas in between. You might hear the DX station perfectly, but you might not hear the hundreds of other operators calling them because those callers are inside your skip zone. This phenomenon is exactly why you must rely on the DX station’s cadence rather than waiting to hear the pile-up clear.
While raw power is often cited as the key to breaking a pile-up, your antenna system plays a far more decisive role in your overall effectiveness. A directional antenna, like a Yagi or a hexbeam, not only focuses your transmitted energy directly toward the DX station but also actively rejects interfering signals from other directions. However, do not be discouraged if you are running a simple wire antenna. A well-placed dipole or end-fed half-wave can still break monumental pile-ups if you leverage good timing, exploit the skip zone, and listen closely to the DX operator. Ultimately, the best antenna in the world cannot compensate for poor operating habits.
Over to You
Working a pile-up is one of the most rewarding challenges in amateur radio. It tests your patience, refines your ear, and forces you to understand both the science of radio wave propagation and the psychology of your fellow operators. Every massive wall of sound is a puzzle waiting to be solved.
Now, I would love to hear from you. What was your most memorable pile-up experience? Do you have a specific tactic that consistently helps you break through the noise, or perhaps a frustrating moment that taught you a valuable lesson?

From my shack to yours, 73 de NW7US.
What was your first major receiver?
I started in the ham radio and shortwave listening hobby in 1972. By 1975, this was my first real receiver. It heard very well, and ignited my lifelong passion for radio.

The R-366/TRR-5 military receiver.
This old radio, the R-366/TRR-5, which is clearly identified on the faceplate in this picture of the military rig, had great ears. It was what I used to hone my Morse code copying skills and to get the hang of how amateur radio operators conducted communications with each other, with CW, AM, or SSB. I hope someday to own one once again.
The R-366
The R-366/TRR-5 is a significant piece of military history manufactured for the Navy Department Bureau of Ships by the Espey Manufacturing Company. Built during an era when the United States Navy required absolute reliability for ship to shore and ship to ship communications, the unit is a testament to the rugged industrial design of the mid-twentieth century. Often referred to as part of the TRR-5 receiving set, this equipment frequently incorporated high quality components and precision engineering including the gold standard Collins Radio Company designs of that period. These internal components were vital in providing the remarkable stability and selectivity needed to pull weak signals out of the dense electronic noise environment found on a crowded naval vessel. It did have heterodyne squeals on a select few frequencies, which any old tube receiver was prone to have, but those did not detract from the excellent capability of the radio.
The Service
For the sailors and radio operators serving aboard ships in the 1950s and 1960s these receivers were far more than just tools for duty. In the often cramped and isolated conditions of life at sea these radios served as a critical psychological anchor. Access to the bands meant hearing the familiar sounds of home or tuning into MARS stations where amateur radio operators facilitated phone patches that reconnected sailors with their families. This bridge to the outside world was essential for maintaining morale and supporting the mental health of military personnel who were otherwise cut off from the rhythms of civilian life for months at a time. Sitting in the radio shack and slowly tuning that large central dial while listening to the crackle of the ionosphere was a meditative escape from the constant hum of shipboard operations. Many ships would pipe ball games and news shows, or music programs, over the ships intercomms, providing health and morale to the personnel.
Operating the Radio
The tactile experience of operating this specific receiver remains vivid in my memory. The layout with its distinct knobs for selectivity phasing and BFO control was designed for the hands of a professional radio operator who needed to manipulate the signal in real time. It required a disciplined ear and a steady hand to copy Morse code through heavy atmospheric conditions but that struggle made every successful reception feel deeply rewarding. It taught me the patience and technical appreciation that have defined my amateur radio hobby for decades. Owning and using a piece of history like this represented a connection to the generations of operators who stood the watch before me.
Traveling the World…
With this historic military receiver, I discovered an entire world as a child in the mid 1970s. I spent countless nights in the quiet darkness of my room with only the warm orange and yellow glow from the vacuum tubes leaking out of the back and top grills and slots of the radio enclosure, as those hot tubes cast soft light on the ceiling and walls. That radio allowed me to travel the globe from my listening position often sitting cross-legged on the floor in front of this big rig. Those late night listening sessions, when I should have been sleeping, ignited a lifelong passion for understanding the vast and interconnected world of shortwave radio as well as medium-wave DXing. I heard International Shortwave Broadcast stations as well as AM broadcast stations from Europe, Asia, the South Pacific, the Atlantic regions, South America, Central America, and North America–all over the world! I listened to amateur radio operators on Morse code, SSB, and AM modes. Ships at sea, aircraft doing transoceanic flights, fishing vessels comms where fishing captains would chat with other boat captains, and even military communications were all at my fingertips on the dial of the radio as I listened to these exotic places by headphones. I even picked up a station from Peru, South America late one night, on the mediumwave broadcast band. That is how great that receiver could hear. Of course, I had a very excellent outdoor dipole antenna that was cut for 160 meters.
What Receiver Was Your First?
What was your first major receiver? Was it just a receiver, or was it a transceiver? When was that? What did you hear that captured your imagination? Do you still have that radio?
I hope to someday have this R-366/TRR-5, once again.
~ Happy DX!

Powerhouse History: WLW, W8XAL, WSAI
The photograph, below, captures a compelling moment of technical mastery during the formative years of American broadcasting, set deep within the inner workings of the Crosley Radio operation in Cincinnati, Ohio, during the 1930s. This was not just a studio but a nerve center for one of the most ambitious radio experiments in history. In the frame, an unidentified announcer sits with a quiet, practiced focus before a sensitive microphone, his presence framed by a formidable wall of equipment that served as the control interface for Powel Crosley Jr.’s broadcasting empire.

WLW, W8XAL, and WSAI
The machinery in front of him represents the sophisticated control panels for three distinct stations, labeled for WLW, W8XAL, and WSAI. These panels were the operational gateway to a signal that redefined the reach of radio. WLW, in particular, earned the nickname The Nation’s Station, and for a brief but legendary period in the mid-1930s, it was granted special authorization by the Federal Communications Commission to experiment with a massive power output of 500,000 watts. This made it the most powerful radio station in the United States, a true technological titan of the era. The signal was so incredibly potent that listeners across North America and beyond often reported hearing the broadcast under unusual circumstances, such as through the metal teeth of fillings, in the coils of mattress springs, or even through the humming of household plumbing.
Beyond the standard AM broadcast of WLW, the inclusion of W8XAL in this control room highlights the critical role shortwave technology played in the Crosley vision. While the standard AM signal was meant for domestic reach, W8XAL served as an experimental shortwave companion, designed to project the Cincinnati broadcasts far beyond the limitations of local and regional airwaves. Shortwave radio waves possess the unique ability to bounce off the ionosphere, allowing signals to travel thousands of miles and transcend national borders. Through W8XAL, the Crosley organization was testing the feasibility of true international broadcasting, turning the modest studios in Cincinnati into a point of origin for listeners located as far away as South America or Europe.
This shortwave capability was a significant leap in the evolution of mass media. It represented a deliberate attempt to overcome the geographical isolation that had defined the earlier, more fragmented era of radio. By operating on shortwave frequencies, the announcers and engineers were participating in a grand experiment to see if a single localized voice could truly become a global one. It was an ambitious pursuit that demanded even greater precision than standard broadcasting, as atmospheric conditions and solar activity could frequently disrupt the long-distance transmission path.
Working in this control room was a task that required both the poise of a performer and the precision of an engineer. Each dial, needle gauge, and switch was a critical element in maintaining the integrity of the broadcast, as the announcer had to carefully monitor the modulation levels to ensure the signal remained clear and stable for millions of listeners. A lapse in focus could mean a technical failure or a broadcast error that reached a massive, dispersed audience in real time. It was a high-stakes, high-pressure environment, yet it functioned as the primary, and often only, window to the wider world for families weathering the depths of the Great Depression.
Powel Crosley Jr. was a man of intense vision, and he understood better than most that radio was the ultimate tool for domestic and international unification. These transmitters were the engine that bridged the vast geographical distance between his studio in Cincinnati and the living rooms of families scattered across the continent and beyond. When people turned their dials to find the station, they were connecting to a piece of engineering that stood at the very cutting edge of the twentieth century. Looking at this image today, it is easy to feel a sense of awe for that era, when the simple act of turning a knob could bring the world into a home, effectively shrinking the vastness of the country and changing the way society experienced culture, news, and shared humanity forever.
Catching Up With QSLs
It’s been sometime since I have posted some of my incoming QSLs as I've been waiting arrival of the last one of my 6m winter DX season cards to arrive, which it finally did yesterday!
Unfortunately the peak of Solar Cycle 25 arrived a little ahead of time, peaking in the early fall rather than later or in early winter which is much more favorable for higher F2 MUFs. Nevertheless, some interesting days were to be had if the propagation patterns were followed closely, particularly after a solar event. Hopefully we will see a second peak of the cycle later this fall as most cycles have a double peak … if it comes in this summer, it’s not going to be of much help for 6m fans.
I started the 2024 6m sporadic-E season with a confirmed DXCC total of 110 countries and hoped to add at least one or two new ones via chordal-hop E or via F2 in the fall. My hopes were indeed met but if the cycle had peaked a few weeks later, the fireworks would have been something much more exciting.

Vacuum Tubes – Electronics at Work: 1943 Educational Film
In the classic educational film titled “Electronics at Work,” produced by Westinghouse in 1943, viewers are introduced to the fascinating world of vacuum tubes. This film highlights the crucial role these devices played in both military and commercial sectors, including radio telecommunications, radar, and various industrial applications. The narrative suggests that vacuum tubes provided the United States with a significant advantage during World War II, particularly in enhancing communication and technology.
The Continuing Relevance of Vacuum Tubes
Despite advances in technology, vacuum tubes remain in use today for several applications, including:
– Transmitting radios
– Medical devices
– Audio amplification systems
– High-frequency applications
Understanding Vacuum Tubes
The film outlines the six basic functions of electronic tubes and illustrates how each type is employed in different industrial and military contexts.
[embedyt] https://www.youtube.com/watch?v=ZJ6rN7WEjbc[/embedyt]
Structure of a Vacuum Tube
A vacuum tube typically consists of two or more electrodes housed within a vacuum inside an airtight enclosure. Key features include:
– Electrode Types: Most vacuum tubes have glass envelopes, although some utilize ceramic or metal casings with insulating bases.
– Leads and Sockets: The electrodes connect to leads that pass through the envelope via an airtight seal. These leads often take the form of pins, allowing for easy replacement in a tube socket, as tubes were a common point of failure in electronic devices.
– Capacitive Design: Some tubes feature a top cap on the electrode to minimize interelectrode capacitance, enhancing high-frequency performance and maintaining safety by separating high voltages.
The Evolution of Vacuum Tubes
The earliest vacuum tubes emerged from incandescent light bulbs, which contained a heated filament sealed in an evacuated glass envelope. When heated, the filament releases electrons into the vacuum through a process known as thermionic emission.
– Electrode Functionality: A second electrode, known as the anode or plate, attracts these electrons if it holds a more positive voltage. This mechanism results in a flow of electrons from the filament (cathode) to the plate, creating an electric field due to the potential difference between them.
– Diode Function: A vacuum tube with two electrodes is termed a diode, which functions as a rectifier. Diodes allow current to flow in only one direction, converting alternating current (AC) into pulsating direct current (DC). This technology is widely used in DC power supplies and in demodulating amplitude-modulated (AM) radio signals.

Do Hams Still Listen to Shortwave? They do in Canada!
Listening to the shortwave commercial stations (along with CB radio) has been a key gateway activity for entry into amateur radio. That was back when commercial shortwave was vibrant and perhaps in its heyday. There is still a very active set of SWLs contributing to the popular SWLing.com website and the legacy work by the well-known Van Horn family to just name a couple. The Spectrum Monitor publishes information about shortwave listening, too. Of course, the Grand Daddy publication, the World Radio TV Handbook is still around. But do amateur operators still listen to the shortwave radio bands? In this article, I want to address the question I just raised with a clear answer: They still do in Canada!
The Radio Amateurs of Canada (RAC) fielded a national survey of Canadian hams in 2021. A total of 2,089 responses were received, of which 1,630 (78%) were from RAC members. Approximately one-third of all RAC members took the time to complete the survey. This is an example of “voluntary response sample” and is not a probability survey. The final report compared responses to known population characteristics which suggested that the realized sample data is generally representative of Province and license characteristics. I’ve just completed a full report from the data which is available on my FoxMikeHotel.com website. The results on shortwave listening are the focus of this article.
The results show that indeed Canadian amateurs listen to the shortwave frequencies outside of ham radio bands. Out of 38 specific operating activities, over a fourth (28.8%) of Canadian amateurs said they are involved in shortwave listening in a typical month. This was ranked 16th out of 38, ahead of QRP operations, Elmering, weather spotting, and other activities thought to be popular in amateur radio. This result may be surprising to the reader. But my further analysis shows a clearer picture of how traditional shortwave listing activity is integrated with other ham activities.
I have included in Figure 1 a map of all license-holders in Canada from the amateur radio regulator, ISED. The provided licensee address was georeferenced to the street-level for the vast majority and city-level for the remainder. There is also a bar chart showing how SWLing varies by Province.
Amateurs in Canada are concentrated all along the Southern border and in the urban centers of the Southeastern seaboard. There is another concentration on the Western coast near Vancouver. For the survey results, the bar chart in the bottom panel of Figure 1 illustrates how shortwave listening varies. A majority of hams in Newfoundland and the Northwest Territory use shortwave radio for listening. Those in Saskatchewan and Manitoba round out those Provinces above the overall survey mark of 28.8 percent. Excluding Nunavut Province with only 2 survey respondents, the lowest engagement in SWLing is Alberta. The remaining Provinces are about equal, in the lower twenty-percent figure.
Do these results make sense? The physical isolation of the two highest Provinces makes using shortwave broadcasts very practical in many ways. But there is more to it as I investigated whether SWLing is a more obscure activity in ham radio or is it more integrated into portfolio of things that current amateur operators do today?
In Table 1, I summarize my crosstabulation of shortwave listening by other activities (some 37 tables). The three groups summarized in the table reflect whether there was a statistically significant relationship between the two activities and, if so, whether SWLing was greater or less when the ham said they participate in the comparison activity. If there is no significant relationship, then shortwave listening is about the same whether the other activity is engaged in or not. If shortwave listening is a surprising yet obscure activity, there would be few other activities associated with it. Or, perhaps there might be no relationship at all with a random assortment of hams tuning into to those bands.
What the results in Table 1 demonstrate is how significantly integrated shortwave listening is with a number of activities central to the hobby. There are only seven activities without an association and one with a negative relationship. Contesters tend to pursue SWLing significantly less. This is the opposite, however, of what DXers report. Ham operators who listen to shortwave bands also practice a variety of popular activities in their practice of the hobby. These findings tend to remove any doubt as to whether listening to shortwave radio bands is fully an integrated part of contemporary amateur radio in Canada.
Another question about these results is whether it is simply a residual activity of the large Baby Boom cohort? Should this be the case, SWLing is likely to age out of existence over the next couple of decades. If so, shortwave listening would be highest among the most senior survey respondents and lowest among the youngest.
In Figure 2, I constructed a line chart of shortwave usage by age group. There is a clear downward trend as SWLing is highest among younger hams than more senior ones. The significance test suggests that this overall age pattern is not significant. The result is that the survey result of a quarter or more of Canadian hams engaging in shortwave listening is not a holdover of amateurs from a previous era of the hobby as younger hams.
Even with there being a non-significant trend in opposition to the Baby Boomer remnant hypothesis, I examined how long these hams had been licensed (tenure) and a complementary question in the survey regarding long many years they had been active. Perhaps it is not age per se but length of experience as a licensed or active ham that might influence whether nor not shortwave listening is attractive. These results, too, showed almost no difference regarding shortwave listening and length of experience or activity in the hobby. This are positive findings for shortwave band usage outside of amateur radio.
To further assess how shortwave listening might be linked to other factors, I compared the rural-to-urban locations of amateurs in the survey. There are no significant differences even when compared within these Provinces. The rural-to-urban locale does not explain why some Provinces have higher shortwave listening levels than others.
To conclude, these are somewhat unexpected findings based upon the rhetoric that ham radio operators tell themselves in the public sphere. We frequently hear that shortwave listening is passe, that the commercial and government broadcasters are retreating, and so forth. These may be factually the case from the supply-side of non-ham shortwave transmissions. But the hams in Canada do listen to shortwave broadcasts or one type or another in addition to participating in the core set of activities that comprises amateur radio. Contesting is the sole specialty that is negatively related to such listening. By contrast, DXers are more likely to listen (30.2% vs 23.6%). There are Provincial variations in listening but no patterns within any of them that vary along the rural-to-urban continuum.
The relationship of SWLing to the rest of the amateur radio hobby’s activities appears well-integrated. While the broadcast sector of the shortwave industry is at a low ebb right now, amateur radio in Canada still embraces listening to the non-ham bands. We do not know how this national survey of Canadian amateurs may compare to those of other nations. However, it is the sole survey of which I am aware that measures the activities of amateur radio operators in such detail. Until we do have comparative surveys, the RAC Survey 2021 is our only objective insight into ham radio activities.
Some readers may view these surprising results through their own “personal windshield” of listening experiences. “Why, I don’t know any hams who listen to shortwave broadcasts,” they might say. Others could counter, “Well, we need some “good” survey data on this issue.” I’ve spent a career conducting surveys, teaching survey research methods to PhD students (and fellow faculty), and advising some of the largest survey organizations in the world, such as NORC at the University of Chicago, the SRC at the University of Michigan, and the USDA National Agricultural Statistics Service to name a few. The RAC Survey of 2021 is not a high quality statistical probability sample costing a few hundred thousand of dollars. But it is the best one I’ve seen to date on a national scale with behavioral measures of amateur radio operators. So while the reader’s experiences on SWLing might indeed be differ, it is the aggregate picture that we have never had national level results like those in the RAC Survey 2021. Do they apply to the U.S.? Well, would you rather go just with your personal windshield to generalize or take the picture these results present as our best guesstimate for similar behavior in the States?
