The historical Alexanderson alternator SAQ, from 1924 did perform very well on Alexanderson Day 2023 and was able to air on two separate transmissions. The weather forcast said rain but only a few showers could be seen during the day and the temperature was around 20C. Lots of visitors was enjoying the two transmissions, the guided technical tours, the antenna walk, as well as all the other activities.
