900 CHIN ON Toronto – The station’s move from 1540 to 900 kHz was approved on January 15. Power will be 425 Watts day and 300 Watts at night. Pattern will be non-directional from a tower NNE of downtown Toronto on the roof of the parking garage of the Korean Philadelphia Presbyterian Church in Don Mills near the Don Valley Parkway, 
South of the 401 Trans-Canada Highway. Unless an extension is requested and approved by the CRTC, CHIN-900 must be on the air by January 15, 2028. License requirements include “programming directed to at least 23 cultural groups in at least 17 different languages.” When asked by the CRTC about their future plans for 900 kHz, CHIN replied: “we have continued to explore the possibility of utilizing a directional antenna system requiring two to three towers for day and night operation. Such an operation would require leasing several acres of land, and of necessity must be located close to the north shore of Lake Ontario to afford protections to U.S. and Mexican stations on the same frequency. A daytime power level of 10 kW, and a night power level of 1.5 to 5 kW could be achieved if a proper site could be located. Our stated intention is to continue to pursue the possibility of a larger site which would support a directional antenna and maximize the potential of this frequency. If such a site were secured, we expect that the time to design, obtain the requisite approvals, and construct the site would be two to three years.” Once the move is made to 900, the station will be allowed to continue broadcasting on 1540, simulcasting 900, for one year, ensuring that all of their listeners have migrated to the new frequency.

Radio 26 de Julio (‘R26’), which broadcasts from the town of Glew, Almirante Brown District, Province of Buenos Aires, has moved to the new frequency of 680 KHz, thus abandoning its previous frequency of 1580 KHz. It is worth noting that this is not the first time this change has occurred, as this station had already been operating at 680 KHz towards the end of 2022, later returning to 1580 KHz. It is also important to note that a few months before that, the new AM 680 RADIO ACTIVA appeared on the airwaves, operated by the same owners of RADIO 26 DE JULIO, and which initially began to rebroadcast the latter’s signal.
Its 42-metre-high transmission antenna is located in the vicinity of its studios (Coordinates: 34°53’55.0‘S, 58°23’40.1’W) and it is unknown whether it continues to use the same Adema TXAM-102 1 kW transmitter to broadcast its signals. We would like to thank our friend and reader ‘Gonza’ for the information. He was the first to inform us of the frequency change of this AM station.

When Audacy flips Rhythmic Throwbacks “104.3 Jams” WBMX Chicago to a simulcast of Sports “670 The Score” WSCR on February 2, its WBMX call letters will return to its former home in Boston on Hot AC “Mix 104.1” WWBX.

The WBMX call letters first gained notoriety in Chicago on then-Urban 102.7 WBMX from 1974 until its flip to Adult R&B “V103” WVAZ in 1988. It would have a much longer run in Boston starting in February 1991 when “Mix 98.5” launched. The call letters would move with the format to 104.1 in August 2009 and everything remained stable until the day Entercom completed its acquisition of CBS Radio in November 2017. “104.3 Jams” launched claiming the WBMX Chicago legacy and swiping the calls from their well-established sister in Boston.

Now with the call letters having served a cumulative 23 years in Chicago and 26 years in Boston, they will return on February 2 to the market where it has still spent more time.

There is an update on 1540 CHIN who had applied to move from 1540kHz to 900kHz with much-reduced power (see NA News in Medium Wave News 71/3 July/August). On 15th January 2026 CRTC approved the move to 900kHz according Broadcasting Decision 2026-12. Once the move is made to 900 KHz, the station will be allowed to continue broadcasting on 1540, simulcasting 900, for one year, to ensure that all of their listeners have migrated to 900. The licensee must implement the technical amendments no later than 15th January 2028.

According to reports, Warner Bros. Discovery and its head in Latin America, Mr. Marcos Brito, reached an agreement with the licence holder of CNN RADIO ARGENTINA (AM 950 kHz), Argentinos Media S.A., owned by businessman Marcelo González, to end broadcasting on 950 kHz, as a result of CNN’s global restructuring, which plans to reduce the number of affiliates in Latin America. CNN Radio will continue broadcasting until 19 December 2025 from the current studios of La Corte Producciones in the Chacarita neighbourhood, and will then broadcast only music programming. When it resumes broadcast in mid-January 2026 the station will once again be known as RADIO BELGRANO and will broadcast from its new studios at WAM Entertainment Company S.A., located at 1080 Pueyrredón Avenue in this city. These changes also mark the beginning of new programming for the station.

3SR 1260 am to rebrand on September 1st as SEN Goulburn Valley from RSN.

SEN are also considering what to do with the Melbourne 1116 spot now that they have acuired the licence for 927 Melbourne, of off RSN, as 927 penetrates the Melboure CBD rf noise floor clearer.

SEN’s recent purchase of iconic Melbourne racing station RSN has prompted speculation of a potential frequency change, raising the question: Will SEN switch from 1116 to 927 on the AM dial in order to achieve better reception, following in the footsteps of 3AW?
It’s now almost 20 years since 3AW swapped its frequency with sister station Magic, switching from 1278 kHz to 693 kHz.
With 693 considered the stronger frequency on the AM band, the switch was made to improve 3AW’s reception, particularly in Melbourne’s inner-city area.
Similarly, SEN 1116 has faced complaints of patchy reception in the past.
Melbourne’s trams are particularly bad for AM reception, with the electrics and metal tracks contributing to degradation of the AM signal, The higher up in the frequency band, the worse the interference. Which is why the lower AM frequencies are considered better for coverage area, strength of signal and less interference.  FM and DAB+ do not suffer from the same reception issues as AM, because the older Amplitude Modulation transmission technology is succeptable to electrical sparks while Frequency Modulation and Digital Audio Broadcast transmission use a different type of transmission system.
