It's Alexanderson Alternator Time!

I'm a bit late with this. The 2011 Alexanderson Day is TODAY, July 3rd (UTC)!

From their web site:

SAQ will be on air on the Alexanderson Day on Sunday 3rd July 2011. We send a message at 09:00 UTC and 12:00 UTC and we start the transmitter about half an hour before each transmission for tuning. The frequency is as usual 17.2 kHz CW.

QSL-reports are kindly received:

QSL reports can be given via:

- E-mail to: info@alexander.n.se

- or fax to: +46-340-674195

- or via SM bureau

- or direct by mail to: Alexander - Grimeton Veteranradios Vaenner, Radiostationen, Grimeton 72, S-432 98 Grimeton, SWEDEN

Note: SAQ is now a member of the Swedish Amateur Association (SSA) and "QSL via bureau" is OK.


Those with VLF capability might want to try for this one. The low frequency can spread out around the world, though noise can be staggering. There is also a WebSDR in the Netherlands which tunes this range.

SAQ is the world's last functional Alexanderson RF alternator. This giant, generator-like machine creates a 200 kW signal into an antenna truly described as majestic. At one time, a network of these linked the world, as they briefly replaced "King Spark" in the era before vacuum tubes.

The well preserved station is now a World Heritage Site. More information is here.
