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.

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 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.

Michael compares the Choyong LC90 Export and Chinese Versions

Many thanks to SWLing Post contributor, Michael Ye (BD4AAQ), for the following guest post:


Twins, Yet Each One Unique – A Comparison of the Worldwide Version of LC90 with its Chinese Counterpart

by Michael Ye (BD4AAQ)

The export version of the LC90 is now available in the market [affiliate link]. Previously, we examined the Chinese version, which has been in the China market since early 2023. Instead of a review of the export version, this article will focus on the similarities and differences between the two LC90 versions – the version that has just started to be distributed outside China and the version that is already being sold in China. A link to my previous article can be found by clicking here.

One thing to note is the name of the manufacturer. In my previous review, I used Chaoyuan, the “pinyin” phonetic of the Chinese characters of the name of the company. As it turned out, the westernised spelling that the company uses is Choyong, or Choyong Electronics.

The LC90, a hybrid radio that combines the Internet radio with the traditional radio, is a bold move and seems to be well-received by shortwave listeners and beyond. Let’s explore what these two versions of the same model have to offer.

Appearance

The two versions of the radio look the same in appearance. However, upon closer inspection, you will notice the language on the buttons differs. The export version has all the buttons labeled in English, while the buttons of the Chinese version have a mixture of Chinese and English.

Traditional Radio

I do not find differences between the FM, MW and SW features of the two versions. Both versions have the specifications as follows: FM: 64-108 MHz, MW: 522-1710 kHz and SW: 2.3-26.10 MHz. Shortwave performance remains excellent. However, for the export version, you could toggle the MW tuning step between 9 kHz and 10 kHz, and the FM tuning step as well, through the setup (gearbox) button, but it does not seem possible to change any tuning step on the Chinese version – this seems to be a matter of software upgrade and so is not really an issue.

On both versions, press MW again to enter LW (153-279 kHz).

Internet Radio

In terms of the stations that can be heard, the Internet radio exhibits significant differences from that of the Chinese version. The Chinese version is designed to exclusively feature Chinese language stations (and a few English language stations) in China. If we were to liken the Chinese Internet radio to a closed system such as iOS, it would be stable, reliable but restrictive. In contrast, the export version could be compared to Android, offering more open, inclusive and customisable user experience.

On the export version, the MENU button provides access to the main menu, which begins with the six continents (excluding Antarctica) and allows users to navigate to the desired country and then select a specific station. Additionally, shortcut keys are available for direct access to MUSIC, PODCAST, NEWS, TAG and LANG (languages).

TAG and LANG for Ai1 and Ai2 Buttons

On the Chinese version, two buttons, Ai1 and Ai2, serve as voice assistants. Activate and speak to them and the radio directly plays the content (Ai1) or displays search results for users to choose from (Ai2). They come in handy when you look for a specific item, for instance the title of a song or a talk show. On the export version, however, the voice assistants have been removed and replaced with shortcuts TAG and LANG.

Add Your Own Stations

The Chinese version has about 1000 Chinese Internet stations built-in. On the worldwide version of the radio, there is a vast number of Internet stations available, literally tens of thousands of them, in different languages, and from different corners of the world. The number is updated from time to time. And that is not all. A really cool feature is the ability to add stations of your choice and it is easy to do with the help of a mobile phone. Unfortunately, this feature for adding your own stations is not available in the Chinese version.

Nano SIM card

The Chinese version comes with a built-in nano SIM card that is prepaid and provides Internet data. To continue using it, simply add credit to the card. In contrast, the export version does not include a prepaid, data-enabled SIM card for the user. Still, the user can use a WI-FI connection or purchase a 4G nano SIM card to insert into the device’s slot.

Some Features Not Discussed Previously

Both versions have the following features:

  • Keyboard backlight;
  • IPS LCD with backlight;
  • Type-C charging cable supplied;
  • TF card supported (to store and play your own music); and
  • Bluetooth for the radio to serve as a Bluetooth speaker.

The integration of high-tech gadgets and advanced devices into our daily routines has become indispensable in this age of the Internet. It is essential to adapt to the ever-evolving nature of the times.

Bottom Line

The Choyong LC90 is an exceptional radio that combines traditional radio features with modern Internet capabilities. It is available in both domestic and worldwide versions. The revolutionary design of the LC90 allows for excellent overall performance in both over-the-air radio reception and online streaming/podcasting.

There is no difference in traditional radio reception and performance between the domestic and worldwide versions of the LC90. However, the Internet features are drastically different, as the worldwide version serves audiences around the world, while the Chinese version is dedicated to the audience in China.

Overall, the Choyong LC90 offers a unique combination of traditional radio and modern Internet capabilities, making it a versatile and high-performing device for radio enthusiasts and music lovers.

Wish List

Is SSB decoding necessary? Well, it depends. The radio primarily caters to broadcast listeners, but both hardcore amateur radio hobbyists and general listeners may find it appealing. While adding SSB decoding can enhance its functionality, it will increase costs and may require additional space, considering it already combines two radios in one device.

There are two switches, the red button (upper right) and the volume/sleep knob (lower right side). Is it really necessary to have both?

On the export version, the “network error” message may occasionally pop up, and the radio would become quiet until human intervention steps in. Is it feasible for the radio to automatically resume play after the network error is cleared?

For some users, the antenna jack is a bit too close to the tuning knob. In most situations, this proximity does not impact the radio’s operation. However, if you need to connect an antenna using a connector, you may encounter difficulty or even find it impossible to plug it in.
