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

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.

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.

LINKS

To see the exact location of where TI4NRH was, open Google Maps and search for the following coordinates: 9.995550958984419, -84.11618361000325 then switch from map view to satellite view.

The main house was where the shiny tin roof is today (2024). Just to the right is another building with a red roof. That is where the wing with the station and the antenna tower were.

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.

Update to Don Moore’s Marine Broadcast List

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!

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, UteHam, 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

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

Radio Reloj, Costa Rica (1990)

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 one) 

by Don Moore

Costa Rica is one of the most visited countries in Latin America. I only visited there once, for three weeks in May-June 1990 when the country was just beginning to become a major international eco-tourism destination. Visitors were few and prices very affordable. Except for a short trip to the Monteverde cloud forest, we spent all our time in the central valley, staying in San José and nearby Heredia. Rather than nature, our visit focused on cultural and historical sites … and a lot of radio stations.

Since the 19th century, Costa Rica has been one of the most literate and educated countries in Latin America. That quality is reflected in its radio broadcasting industry, which has always been very professional. Curiously that’s even reflected in station verifications. Almost every Costa Rican shortwave station that I’ve verified had a professionally printed QSL card.

Despite being one of the smallest countries in Latin America, Costa Rica had a lot of shortwave radio stations. I have fifteen in my logbooks and some of the most famous ones were already off the air when I started DXing. Unfortunately, shortwave broadcasting from Costa Rica ended almost twenty years ago so there’s no more to be had. It is still possible to log Costa Rica on medium wave but it’s not as easy as it once was. When I started DXing in the early 1970s, stations in the San José were spaced twenty-five kilohertz apart. That meant that every other station, such as Radio Sonora on 675 kHz and Radio Columbia on 725 kHz, was on a split frequency that fell between the normally assigned 10 kHz channels. I logged nine Tico stations on medium wave while DXing from Pennsylvania in 1972-1981 and only one of those, Radio Reloj on 700 kHz, was on an even channel.  Those split channels were eliminated in the 1980s so logging Costa Rica on medium wave is no longer a slam-dunk.

I visited a lot of radio stations and took a lot of photos on my one long-ago trip to Costa Rica. I’m going to focus on just five shortwave broadcasters in this first look at Costa Rica. The others will be featured in two or three future columns.

In the 1970s the first Costa Rican station most shortwave DXers heard was Faro del Caribe, or Lighthouse of the Caribbean. This religious station used two kilowatts on 9645 and 6175 kHz and got out surprisingly well as long as there wasn’t a more powerful international broadcaster also using the same frequency. In the late 1970s they added 5055 kHz in the sixty-meter band.

When I visited in 1990 the antennas were located right next to the studio building. The site was outside the city of San José when the station was founded but gradually a residential area built up around it.

Fortieth Anniversary pennant from 1988. When Faro del Caribe began broadcasting on February 23, 1948, it was the first Evangelical Protestant radio station in Central America.

For DXers, Radio Reloj was one of Costa Rica’s best known radio voices for several decades. The station was founded as Radio Cristal by Roger Barahona in 1945. The shortwave frequency of 6006 kHz was added in the early 1950s. In 1958 the station was renamed to Radio Reloj when the format changed to focus on news and community announcements with very frequent time checks. (Radio Reloj means Radio Clock.) Roger’s brothers Isaac and Francisco had joined the broadcasting company and Radio Reloj was assigned the callsign TIHB for Hermanos Barahona (Barahona Brothers). Continue reading
