RTÉ Longwave End of Broadcasting: April 14, 2023

Live off-air recording of some of the last day of programming from the Raidió Teilifís Éireann (RTÉ) Radio 1 longwave station on 14 April 2023 beginning at 11:55 UTC on the frequency of 252 kHz. The signal originated from a transmitter located at Clarkestown/Summerhill, County Meath, in the Republic of Ireland, reported to operate with a power of 150 kW during the day (and 60 kW during the night). The transmitter was capable of operating at 300 kW. The station used a 248-metre high single-mast antenna.

RTÉ Radio 1 is a general-interest, news, talk, and music station. It now uses FM, satellite, streaming, and cable services.

The recording starts with the final minutes of the "Louise Duffy Show," followed by the "RTÉ News at One" (which featured reports on U.S. Pres. Joe Biden's visit to Ireland) and then the first 13 minutes or so of "Liveline," an interview and phone-in chat show. The recording ends with an announcement of the shutdown of the longwave service.

Reception of the 252 kHz signal was reasonably good but it suffered from slight co-channel interference from a station in Algeria and local noise at the reception site.

RTÉ Radio 1 programming on 252 kHz ended at 23:03 UTC on 14 April 2023 and was replaced with a repeated announcement of the cessation of broadcasting on longwave and information about other ways to hear RTÉ Radio 1. It begins with the RTÉ Radio 1 interval signal "O’Donnell Abú." Examples of the announcement are included in the second three-and-a-half-minute recording which starts at about 12:34 UTC on 15 April 2023. In this recording, most of the interference has been removed by an audio filtering technique. The closedown announcements ended on 18 April 2023 at 09:59 UTC and the transmitter then fell silent.

The broadcasts were received by the Web-interface wideband software-defined radio at the University of Twente in Enschede, The Netherlands, with a "Mini-Whip" antenna in synchronous AM mode with 5.08 kHz RF filtering.

RTÉ GAA All-Ireland Finals: September 21, 2014

Earlier today, I was able to catch the end of the GAA All-Ireland Football Final (Kerry v Donegal) on RTE 17,495 kHz, starting around 15:50 UTC, with my WinRadio Excalibur receiver and sky loop antenna. 

I enjoy hearing sporting events broadcast over shortwave–perhaps it’s my imagination filling in the gaps from the live coverage or the washy sound of the crowds roaring.  Regardless, RTÉ has a long-standing track record of broadcasting the GAA finals on every medium possible.

I recorded the last few minutes of the game and nearly an hour of commentary afterward. Enjoy:

RTÉ Radio broadcast of GAA finals

Sunday afternoon--one week ago--I was at home to catch a bit of the GAA finals via RTÉ on 17,725 kHz, starting around 15:00 UTC.

I enjoy hearing sporting events broadcast over shortwave–perhaps it’s my imagination filling in the gaps from the live coverage or the washy sound of the crowds roaring.  Regardless, RTÉ has a long-standing track record of broadcasting the GAA finals on every medium possible.

As I listened to the live broadcast, Sunday, I read Norman Freeman’s account of listening to the GAA finals from a ship in the Indian Ocean, back in 1956. He writes:

“Almost 50 years ago, listening to the All-Ireland by radio was uncertain and frustrating.

In 1956, RTÉ knew how much the All-Ireland meant to the Irish diaspora. Arrangements were made with the authorities in the then French Congo to have the match rebroadcast the following evening, on the powerful short-wave transmitter in Brazzaville.

The time and frequencies were published in the Irish newspapers. This information was sent by letter to the Irish on oil rigs off the coast of Borneo, to round-the-year painters on Brooklyn Bridge, and to missionaries within sight of Mount Kilimanjaro.

I had noted the time and frequencies before I was sent out to Mumbai to join my first ship, the Amra, as second radio officer. The hurling final was between two giants, Cork and Wexford.”

While Freeman doesn’t miss the uncertainty and fickle nature of shortwave radio as the messenger of his favorite sporting event, his look back is certainly nostalgic. After all, Radio Brazzaville transported Freeman and his boss back to Ireland for the length of the game. And to RTÉ’s credit, they continue to broadcast to the Irish diaspora on shortwave radio, if only for this event.
