SAQ Grimeton scheduled to air on UN-Day, Oct 24th 2026.
SAQ was put into commercial radio traffic on December 1st 1924, at first on 16.2 kHz. In mid December 1924, the frequency was changed to 16.1 kHz and on Dec 24th 1926 it was changed back to 16.2 kHz. On March 10th 1927 SAQ’s frequency was again changed, this time to 17.0 kHz, a frequency previously used by Italian station IRC in Rome.
Only two weeks later, on April 3rd 1927 SAQ’s frequency was again changed, now to 17.2 kHz, a frequency previously occupied by LPV in Buenos Aires, in order to provide “suitable noninterfering wave channel for new Belgian station ORU Ruysselede”, according to the traffic manager at RCA.
17.2 kHz has since then, except for a short period in the 1950’s when SAQ was transmitting on 17.25 kHz, been the frequency we all now belongs to the historical Alexanderson alternator SAQ at Grimeton Radio Station in Sweden.
On UN-Day, October 24th, 2026, SAQ is scheduled* to spread a peace message to the World on 17.2 kHz CW.
