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.  Retails for $94.99 USD for Internet distribution (discounted pricing for upgrades available).

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 →

A little barefoot ultralight MW DXing . . . in which my mental status is questioned

33 Replies

By Jock Elliott, KB2GOM

About 10 days ago, the Better Half and I visited my wife’s sister in Sodus, NY, a small town in the western part of the state near the shores of Lake Ontario.

First consideration when packing was – never mind the underwear and the toothpaste – what radios shall I take? I decided to go light . . . just a CCrane Skywave SSB and a Uniden BC125AT analog-only scanner.

In the predawn hours on a handful of mornings, I decided to see what I could hear on medium wave with the diminutive Skywave SSB. The Skywave is an “ultralight” radio – under 20 cubic inches in volume. Because the Skywave’s plastic case is so small, the ferrite antenna within it is very small . . . less than 3 inches long. It is by no means a huge antenna for grabbing signals.

It was Gary DeBock who pioneered ultralight DXing with tiny generally inexpensive radios. As a ham radio operator, he had worked 144 countries using a Heathkit 1-2 watt kit transmitter he had built. In the process, he learned a great deal about propagation.

In 2007, he decided to see what he could do with a cheap pocket radio, a Sony Walkman SRS 59. At 1 am on an autumn night from his home in Washington state, he put propagation and operating skill to work and heard three distant medium-wave stations: a couple from Japan and one from Korea. He posted his results on the internet in November, 2007, and he got a lot skeptical feedback: How could you possibly do this?

His response (in essence): Try it for yourself.

Some people did try for themselves; some with great success. One DXer from Canada logged 300 stations in 30 days. Interest in MW DXing with pocket-sized consumer radios took off, and ultralight DXing was born.

So, in the predawn hours in Sodus, NY, I decided to give ultralight DXing a try . . . barefoot . . . that means with no external antennas or signal boosters . . . just me kicked back in a recliner, the CCrane Skywave SSB, and a pair of headphones. Simple.

Before we proceed, you need to understand that my DXing style might charitably be described as “lazy.” Instead of laboriously turning the tuning knob, I use the seek function on the CCrane Skywave. I simply press and hold for a moment the up or down arrow and wait for the Skywave to stop at the next signal it detects. Then, if I feel that the signal might be enhanced by re-orienting the antenna with respect to the signal, I wiggle the Skywave around in my hand and listen for an improvement in what I am hearing through the headphones.

The results: I logged (among others) Atlanta, Georgia (493 miles) and Charlotte, North Carolina (588 miles) on the CCrane Skywave SSB with its tiny internal antenna. Also received: Boston, Philadelphia, New York City, Baltimore, and Toronto and a bunch of unknowns.

One afternoon, I decided to see what distant stations Skywave might receive during the daylight hours. I was kicked back in the recliner with headphones on, doing my usual, waving the Skywave around in the air to optimize the reception. My sister-in-law started laughing. She said I looked like a demented band leader, conducting a silent orchestra! I tried to assure her that my mental status was OK and that I was trying to optimize the signal. I’m not sure it worked.

But one thing is certain: barefoot ultralight MW DXing is fun. All you need is a tiny radio, a bit of darkness, a pair of headphones, and a willingness to be surprised.

High Noon: Belka MW shootout part 2, with a review of the AFA200C active MW ferrite antenna

by 13dka

When I reviewed the updated Belka (gen3, 2022) for its MW/LW performance in October last year, I just wanted to know if it’s any good with just the whip antenna and used the XHDATA D-808 as a reference radio because it’s a Jay Allen 2.5-star average performer on MW and my expectations were not high for MW reception on a short whip.  To my surprise that average bar turned out way too low for the Belka!

That was sure asking for a comparison with the most sensitive MW radio I have and gave me hope to use the Belka for ultra-portable MW DXing on the move.  The omnidirectional whip doesn’t allow me to null out unwanted co-channel interference though, therefore I wanted to find a reasonably sized loopstick antenna to pair with the Belka.  Continue reading →
