2024 Solar Eclipse DXing

by William Scott, WE7W

DXing the mediumwaves promises to be an exciting event on April 8 during the 2024 total solar eclipse. I’ve been mulling over the DX possibilities a lot lately and have come to some conclusions. I think it boils down to three promising DX scenarios:

Scenario 1. For those who live within or very near the path of totality (see Figure 1), I believe best chances of DX would be first to listen to your southwest, along the path where totality is approaching. Darkness will already have happened in that direction, and a certain amount of residual de-ionization of the ionosphere will still remain. After the point of totality passes your location, I would swing my attention to the northeast.

Scenario 2. For those living within about 800 km (or about 500 miles) of the path of totality I believe best chance would be a perpendicular path across the totality path to a point roughly equidistant on the other side. This puts the signal reflection point right at the center of the totality path, or the deepest point of darkness.

Scenario 3. For those living more than about 800 km from the path of totality I believe best chance would be along a line from your receiving site to a perpendicular intersection to the totality path. This should define the greatest shaded path.

I think that scenarios #1 and #2 have the best possibility for DX.

Figure 1 (Click to enlarge)

Across the U.S. and Canada, from its entry at Texas to its exit through NE Canada and into the Atlantic Ocean, the totality path width varies from a maximum of 199 km at U.S. entry to about 160 km at Atlantic exit, or 123 to 99 miles.

Important to keep in mind – skywave signal strength analysis is based almost entirely on the condition of the ionosphere at the reflection point, not at the receiving site. For single hop propagation, normally the reflection point is at the halfway point to the station along the great circle route. That 800 km distance from the totality center I wouldn’t hold as gospel. I’m throwing that figure out as a point where scenario #2 may start to transition to scenario #3.

Timing is of the essence for DXing. The shadow velocity exceeds 1000 mph, increasing from 1587 miles per hour at Eagle Pass, Texas to 3176 mph at Houlton, Maine. You may have only minutes to DX. I’ll be in Rochester, NY at the time of totality, and we are right at dead center. I’ll be scenario #1. My plan is to listen to my southwest initially, where totality is approaching. I’ll be listening particularly for WLW-800 in Cincinnati, OH, WHAS-840 in Lexington, KY, and others along or near that path.

Scenario #2 possibly holds the most promise. Calculate your distance to the path center line and look for stations on a direct line across the totality path and at an equal distance on the opposite side of the path from you. One such scenario might be WSB-750, Atlanta to a reception point in northwestern Illinois, central Iowa, or southern Wisconsin or southern Minnesota. Many possibilities on cross-paths exist here. I feel best results would be with a signal path that crosses the path of totality closest to 90 degrees.

A question was raised about the possibility of DX from Spokane, Washington, an extreme distance from the path of totality. That particular scenario would be scenario #3, more than 800 km to the path of totality. Maximum obscurity should be when northeast Texas (let’s say the Dallas area) is experiencing full totality, as the great circle line to the totality path intersects at approximately 90 degrees to the line at that point. This would be at about 1848 UTC. I would listen for any signals along a great circle path between Spokane to anywhere from the Dallas area and northward. Obviously, Spokane to Dallas is an extremely long one hop path, at about 2450 km. At that distance, the reflection point is near Denver, which will have a solar obscuration of 65.1% at maximum.

A Dallas area reception would be next to impossible I would think, but there are many more stations along that great circle path one could try for. Closer stations will obviously move the reflection point closer and start to reduce the solar obscurity. I did a scan along that path and there are some 340 stations within 200 km either side of the line of the great circle path between Spokane and Dallas.

A presumed Scenario #4.

Another scenario was suggested by Nick Hall-Patch, that of reception parallel to the path of totality and outside the 100% totality band. The 2017 solar eclipse across the northern part of the U.S. was DXed extensively and produced some interesting results, which are well documented in IRCA Reprints. Check their document repository here:

http://dxer.ca/images/stories/2019/irca-reprint-index.pdf

Nick reports: “The receptions of KSL-1160 described in IRCA Reprint # G-096 showed the results of 3 DXers listening across the path of the eclipse (Scenario #2), but the fourth, Dave Aichelman, was monitoring KSL from a location parallel to the eclipse path ( sort of Scenario #1?) and got very good enhancement as well.” We might name this “Scenario #4”.

I checked out # G-096, that documents the KSL reception from the solar eclipse of 2017. It looks like the Dave Aichelman (at Grants Pass, OR) reception of KSL had a mid-path reflection point of about 95% solar obscurity. The distance was 971 km (602 miles). Graphing KSL, I see it has a nice fat low angle takeoff and impressive skywave strength at 900 km, some 1.3 mV/m for that distance. (ed. note: A map of fractional solar obscuration is in Figure 2, easily converted to the percentage figures quoted in this article. )

Better yet, the article indicated Aichelman also received XEPE-1700 across the Mexican border from San Diego too. That was a mid-point reflection obscurity of only about 83% as far as I can deduct from the maps. The distance was 1238 km (769 miles). The mid-path reflection point there was in the neighborhood of 700 km from the central path of totality.

So, DX is indeed possible where both the station and the receiver are off center from the totality path. It’s looking like anything from at least 80% obscurity at mid-path reflection may have some real possibilities, particularly if you are at the end nearest the path of totality. Lower obscurities, perhaps down to 50% or so may even produce results.

Using my pattern mapping program which has extensive area search capability, I’ve compiled a list of all US and Canadian stations that fall within the 2024 Solar Eclipse path of ~100% totality. There are 456 stations. Results are drawn from the March 20 FCC LMS database and Industry Canada database. Sorry I don’t have Mexico available.

If you would like this list, download from this link. https://www.mediafire.com/file/125ih5yrmw4puib/2024-eclipse-stations-by-longitude.zip/file

Across the US and Canada, from its entry at Texas to its exit through NE Canada and into the Atlantic Ocean, the totality path width varies from a maximum of 199 km at US entry to about 160 km at the Atlantic exit off Newfoundland, or 123 to 99 miles. 456 stations are found in this eclipse path. I purposely set the path width to 210 km from start to finish. This gives a few km slop on both sides of the 100% totality path for good measure.

Unzip the downloaded .ZIP file, where you will find 3 files. The stations in each file are sorted by longitude, from west to east. This gives us the progression of the eclipse path, with the eclipse starting at the first station in the list and ending with the last station.

File #1 is a simple text file.

File #2 is in .CSV format. You can easily input it to an Excel file.

File #3 is in .HTML format. It includes links to each station’s Google Map latitude-longitude coordinates for the satellite view of the transmitter tower array.

Another link takes you to the FCC AM Query link for that station. I hope these files are beneficial. There should be many propagation path possibilities outside of this list as well.

http://7dxr.com/4all/100km8Apr-movie–Frissell-HamSCI.mp4

The latter is particularly interesting, as it shows the moon’s shadow at 100km height above the earth, an area of special interest to DXers, as it is the lower edge of the E-region of the ionosphere. Note especially that as the eclipse ends over the North Atlantic Ocean, that there is a temporary darkness path between Europe and North America, because night will already have fallen in Europe. So will there be blips of TA DX in eastern North America as the eclipse passes by? Listen, and find out!

Finally, our DX could be of interest to ionospheric physicists also. The rapidly changing listening conditions will be indicating a similarly turbulent ionosphere, and DXers’ documenting those listening conditions through SDR recordings could provide information that will be useful to scientists who want to gain a better understanding of the Earth’s ionospheric dynamics.

HamSCI is an organization of volunteer citizen-scientists and professional researchers who study upper atmospheric and space physics, and will be interested in examining MW DXers’ wideband SDR recordings made during the eclipse period, and indeed, in having DXers assist with HamSCI’s research. (see https://hamsci.org/eclipse. Especially if you are an amateur radio operator, there are several other ways that you might also contribute to the project.)

How I Figure Out and Decide What To Log On Shortwave….

4 Replies

by Paul Walker, Program Director, KSKO 89.5 McGrath Alaska (not my radio, stock photo)

Some have asked, so I thought I’d share. Everyones DX’ing goals and rules are different and that’s what makes the hobby interesting……these are mine. If I logged everything, I’d have multi gigabytes of audio on a weekly basis that I’d never ever finish sorting through. Alaska seems to be a great place for direct long path, off the back or over the pole reception of alot of signals!

I have a schedule site (Eibispace.de) that gives me the frequency, schedule, broadcaster, transmitter location, language and target area of the signal. I then quickly work out in my mind where I am in relation to that.

Like something beaming from Oman or the UAE to the Middle East, I may be off center from the main lobe, but it’s a long path trip for that signal. Something from Botswana to Northern/Western African, I am in near the direct center main lobe of the long path of that, as I recall looking up at one point. Or I could be getting something off the back from Galbeni or Santa Maria de Galleria.

I quickly work that out in my head and ten figure out if that’s actual DX. Then i quickly evaluate the signal.. quality over quantity. I know what many signals are capable of here at some point or another.. and If I’m getting a noisy, fadey signal where I know anything from alot better is possible to common, I won’t log it or record audio.

I do regularly log some poor to fair signals because they are rare here and usually low power. (Tarma 4775khz, Brazil 15190khz, et al)

I also take into account what others have logged and how well. I go after the lesser heard or those not heard as well by others. I live in a very unique location for DX and I want to use my time wisely by learning about what I hear, what I hear and going after whatever my personal definition is of the most worthy signals to log.

I typically do not log anything of which I am in the target area or spill over area of. Like Radio Romania International, China Radio international.. because thats just easy pickin’s for me…. with a few exceptions

This is not to say anyone who logs only target area or easy stuff is doing it wrong. We just go after different things and do things differently.

If I logged everything I heard, I’d have multi gigabytes of audio on a weekly basis that I’d never ever finish sorting through and as Thomas Witherspoon knows, I’m behind with processing my audio all the time as it is!

Don Moore’s Photo Album: Costa Rica (Part Two)

Many thanks to SWLing Post contributor, Don Moore–noted author, traveler, and DXer–for the latest installment of his Photo Album guest post series:

Don Moore’s Photo Album: Costa Rica (Part Two)

by Don Moore

It’s been three months since the last time I put together one of these pieces because I was busy finishing my book, Tales of a Vagabond DXer [Note: SWLing Post Amazon affiliate link]. You may have seen the announcement about it here a few weeks ago. This series should appear more regularly in 2024 as I plan to concentrate on small writing projects for a while!

Back in August, we looked at five Costa Rican shortwave stations that I visited in 1990. This time I’m going to feature just one station, but a station with a very interesting story. My book has an updated and rewritten version of the article I wrote about it for Monitoring Times magazine in the early 1990s. But the book doesn’t have many photos as adding those significantly increases the price. So, here are the pictures and a little bit about the station.

This seven-and-a-half-watt transmitter was the first transmitter for TI4NRH, the first shortwave broadcast station in Latin America. It was built by Amando Céspedes Marín in Heredia, Costa Rica in 1928. Don Amando operated a small medium wave station and hoped that by using shortwave he could reach listeners in all of Costa Rica. Instead, he gained an audience all around the world. His little TI4NRH became one of the most popular radio stations for shortwave listeners throughout the 1930s until he shut it down at the beginning of World War Two. This portrait of Don Amando was made around that time.

I remembered reading about TI4NRH in an old-timer’s article, so while I was in Costa Rica I went to Heredia hoping to find someone who could tell me where the station had operated from. I wanted to get a picture of the building. Instead, I found that everything was still there in the dimly lit backroom of the family house. (The pictures are grainy as the room was very dark.) Don Amando had passed away in 1976 but his never-married daughter, Lydylia, still lived there and treated the room as a shrine to her departed father.

The Céspedes family house was on a side street a few blocks south of the main plaza in Heredia. The radio station was located in the middle section, behind the white door.

Plaque on the front door commemorating the building as the birthplace of radio in Costa Rica.

Financial support from listeners helped TI4NRH buy new transmitters and raise power. This 300-watt transmitter was the last one used.

Radio amateurs in the USA and Canada raised money to buy and ship this antenna tower to TI4NRH in the late 1930s.

Nothing was removed after the station closed down but the space became a storage room for the family. This is how it looked in June 1990.

The bottom of that original 7 ½ watt transmitter. Unfortunately, the photo came out very dark in the dimly lit room.

The walls were covered with yellowing 1930s amateur radio QSL cards.

This letter written by Arthur Kopf, an American working in the Panama Canal Zone, was the first report received by TI4NRH. That made it the first reception report ever written to a Latin American shortwave broadcast station.

Don Amando’s daughter Lydylia was the guardian of her father’s legacy.

A view showing the house and neighboring antenna tower.

TI4NRH was only a hobby for Don Amando. He made a living by operating a print shop and photography studio. With financial support from the Zenith Corporation, he published a monthly radio magazine (primarily in Spanish) for several years in the 1930s.

In 1928, Philadelphia DXer Charles Schroeder became the first North American DXer to log a Latin American SWBC station when he heard TI4NRH. He not only got a QSL for his reception, TI4NRH sent him a beautiful chair made out of Costa Rican tropical hard woods. The chair was sent in pieces with instructions for assembly and arrived in just twelve days. Mr. Schroeder passed away in 1956, but in 2005 I heard from Schroeder’s daughter, who still had the chair. She sent these photos.

Finding TI4NRH was like finding an unknown time capsule. It was one of the biggest highlights of both my DX career and my travels. And I always hoped to return. In the late 1990s I learned that Lydylia had passed away and that one of her nephews had moved into the house. Sometime around 2010 the antenna tower had become unsafe so the family had it torn down and sold for scrap. However, other than donating a few items to the city museum (something Lydylia had refused to do), the family continued to hold on to Don Amando’s legacy. In 2017, a group of Costa Rican radio amateurs visited the house and published their photos, which were much better than my old ones.

I would like to say that everything is still there for the next visiting DXers to see. But in looking for links to include in this piece I came across some very sad news. The house was demolished in July 2021. Apparently the next generation of the family (Don Amando’s great-grandchildren) had no interest in maintaining the old house and Costa Rica doesn’t have a good program to preserve historical sites. So the city of Heredia had the house torn down. The news article I found (which was very critical of the destruction) didn’t even know what had happened to the station memorabilia that had been in the house. So, unfortunately, this story does not have a happy ending.

Mediumwave DXer logs KFIZ from Arctic Finland

Many thanks to SWLing Post contributor, Ulis Fleming, who shares the following article from KFIZ via Twitter. I love these articles where a mediumwave DXer blows the minds of a small AM radio station’s staff!

Finnish man hears KFIZ radio transmission on radio in Artic Circle

A man from Finland contacted KFIZ recently to let us know he was listening to our station IN Finland earlier this month. And while it doesn’t sound like such a big deal since we do announce you can listen around the world on the “Tune In” app, this person actually heard us on the AM spectrum of frequencies.

Jari is a self described AM radio enthusiast in Finland that says he is passionate about listening to and identifying AM stations from around the world.

In early December, Jari travelled about 750 miles from his home in southern Finland, by train and car, to an isolated area in Northern Finland, well into the Artic Circle, where he has a base station set up designed to pull in AM radio signals from around the world. Jari says conditions are ideal there because there is ample space for long antennas and little to no man-made electrical noise or interference.

On December 4th at 6:00 Universal time, which would have been midnight local Fond du Lac time, Jari recorded a transmission on his receiver. Its very faint but it’s our station’s radio ID that we play often throughout the day that says “News Talk 1450, KFIZ Fond Du Lac – a Mountain Dog Media Station.”

Given how hard it is to hear, you can respect the fact that Jari now has transmissions confirmed from over 800 stations from North America.

While generally AM radio waves only travel at most 100 miles from the transmitting antennas, with the right conditions, usually during the nighttime hours, AM radio waves can reflect off the ionosphere and propagate past the curvature of the earth, a phenomenon called “skywave” propagation.

So from all of us here at KFIZ, if you are listening locally, on the tune in App, or isolated deep within the Artic Circle, we want to say thanks for listening.

Marine Broadcast List Updated

By Don Moore

I just updated my by-time listing of scheduled marine broadcasts in the MF 1600-3400 kHz range. This is primarily based on the by-location listings at the DX Info Centre website. Of special interest at the moment is Iqaluit Coast Guard Radio in Canada which uses six different transmitter sites in the Canadian Arctic. These seasonal broadcasts will be ending soon with the close of Arctic navigation.

The spreadsheet also includes a tab of selected scheduled marine broadcasts on HF frequencies. It does not include easier stations such as the US Coast Guard or the stations in Australia. See the DX Info Centre for complete by-frequency listings.

Announcing DXtreme Monitor Log 14!

4 Replies

Many thanks to SWLing Post contributor and supporter, Bob Raymond with DXtreme who shares the following product announcement:

Product Announcement

DXtreme Monitor Log 14™

DXtreme Software™ has released a new version of its popular logging program for radio and TV monitoring enthusiasts: DXtreme Monitor Log 14. Its familiar, uncluttered, industry-standard Windows® interface lets listeners and DXers log the stations they’ve heard using features that enhance their monitoring enjoyment.

New Features in Version 14

Signal Modes, Transmission Modes, Grid Square Tracking

We added a Signal Modes field to let users specify the signal mode their receiver is tuned to (for example, AM, CW, FM, LSB, USB, RTTY, etc.) plus a Transmission Modes field to let users specify the transmission mode the station is transmitting (for example, CW, FAX, FT8, HFDL, MIL-STD-188-141A, SSB, STANAG 4285, etc.). And we added Signal and Transmission Mode modules to let users maintain tables of signal and transmission modes.
We added a Transmission Mode Details box to allow users to type free-form information about the transmission mode received, such as baud rate, bandwidth, etc. (for example, 1200bps/L). New Log Variables enable users to share Signal, Transmission, and Detail mode information so readers (and users) can reproduce the monitoring environment and log (or relog) the stations. Here are two examples: “1200bps/L STANAG 4285 crypto tfc on USB” and “MIL-188-110A/B continuous mode idle on LSB.”
We added support for tracking Maidenhead grid squares, which is useful when monitoring/logging stations not located in traditional countries, like aircraft and ships operating in international airspace and waters. Grid squares are calculated from specified latitudes and longitudes. Both Performance and Stations reports let you track grids. Search functions let you find log entries for viewing or editing based on their grid squares.

Verification By Improv Imaging

Similar to the legacy Verification By Audio feature, where the presence of an audio file in a log entry designates the station as “Verified By Audio,” we added a Verification By Improv Imaging feature which counts the station as “Verified By Improv Image” if the Shows ID check box on the Improv Imaging tab is selected, indicating the presence of an ID on the window of a captured digital software application (such as PC-HFDL). Performance, Stations, and Log Entries reports let you track verifications by traditional QSLs, presence of Audio files, and presence of Improv Images for which the Shows ID check box is selected.

Schedule Checker Monitoring Advice and Tuning

When Schedule Checker advises users to monitor a station for a new or verified Country, it does so now for the Class (SWBC, Ute, Ham, etc.) and QSL Type (Verified By QSL, Audio, or Improv Image) selected in Properties. The foreground and background colors that indicate the Schedule Checker’s monitoring advice can be defined by users in Properties. The colors appear in an upgraded legend on the Schedule Checker.
Users can now tune their radios to the schedule item’s signal mode and frequency by selecting the desired signal mode in the Signal Mode list box and double-clicking the schedule item.

Solar Indices Enhancements

Acquisition of current solar indices has been improved on the Monitor Log and Schedule Checker windows. • Editing of solar indices has been added to the Monitor Log window for when NOAA is down.
We restored historic solar indices adjustments based on date and time changes made on the Monitor Log window provided users have downloaded historic solar indices from the NOAA FTP site into the Solar subfolder. An interface is provided on the Edit menu of the Monitor Log window for this FTP activity.

For more information about New Features, click https://www.dxtreme.com/monitorlog_whatsnew.htm.

Standard Features

Logging Stations

Monitor Log 14 lets users log all kinds of stations: radio, television, broadcast, utility, Amateur Radio, military, etc. across the radio spectrum.

Finding Stations to Monitor

The Schedule Checker lets users import schedules from Aoki, EiBi, and FCC AM web sites and display broadcast schedule data according to the filter criteria they specify. Users can filter schedule information by band, frequency, station, country, time of day, language, and more. EiBi schedules also include utility stations.

For each schedule item, Schedule Checker queries the Monitor Log 14 database to let users know – through user-defined, foreground and background display colors – whether they need to monitor a station for a brand new or verified country. The colors appear in a legend on the Schedule Checker window. When Schedule Checker advises users to monitor a station for a new or verified Country, it does so for the Class (SWBC, Ute, Ham, etc.) and QSL Type (Verified By QSL, Audio, or Improv Image) selected in Properties.

Reporting Reception

Users can create customized paper and e-mail reception reports for sending to stations plus log entry data shares for reporting catches to clubs and magazines. Using the Script Editor window, users can create and edit scripts that format reception reports, eReports, and shares to their liking. The software prompts users to select the script they want to use. Dozens of scripts come with Monitor Log 14. Users can also send eQSL requests to hams automatically via the popular https://www.eqsl.cc site and update their databases with downloaded eQSL.cc Inbox records.

Imaging

Improv Imaging lets users associate ad hoc images with log entries using Capture, Scan, and Clipboard functions. Captures of stations received on digital applications, waterfall displays, facsimile and Amateur TV pictures are popular. The Improv Imaging tab and Application let users view images anytime, and an Improv Image Explorer lets them peruse their entire collection and display associated log entries. A QSL Imaging facility functions the same as Improv Imaging for associating QSLs.

Other Features

Rig Control — Retrieves the frequency and mode from supported radios and permits tuning from the Schedule Checker and Direct Tune. Rig control is provided through integration with Afreet Omni-Rig (http://www.dxatlas.com) and CAT for SDR applications like SDR Console (https://www.sdr-radio.com) and SDRuno (https://www.sdrplay.com).
Audio Archiving — Lets users maintain an audio archive of stations heard.
Reporting and Searching — Produces Performance, Stations, and Log Entry reports that track the performance and progress of the user’s monitoring station and provides criteria-based log entry searches.
Documentation — Context-sensitive Procedural Help, Field Help, and Microhelp are accessible on every window to provide instructions quickly. Installation Instructions and a Getting Started Guide also included.

Supported Operating Systems, Pricing, Contact Information

DXtreme Monitor Log 14 runs in 32- and 64-bit versions of Microsoft® Windows® 11, 10, 8.1, 8, 7, Vista® XP.
