On 4 July, the World Heritage Grimeton Radio Station in Southern Sweden will broadcast its annual Alexanderson Day message to the World. The station, SAQ, transmitts at 17.2 kHz CW (yes kHz) from its 1928 Alexanderson Alternator.
First transmission startup is at 0830 UTC with a message sent at 0900 UTC.
Its second transmission startup is at 1130 UTC with a message sent at 1200 UTC.
Both can be seen live on YouTube at Alexander SAQ Grimeton Association - YouTube
Why is this important? Because Grimeton was the forerunner for Morse messages from Europe to North America in the 1920’s and '30’s. Ken
