----------------------------------

The Alexanderson Alternators at Grimedon, Sweden are the last working
examples of this  historic form of radio transmitter that consisted of
essentially a huge alternating-current generator connected to an
proportionally huge antenna. As the message says, the Grimedon alternators
operate at 17.2 kHz. That's a bit below the lowest tuning range the Elecraft
rigs offer, but within the range of some general coverage communications
receivers out there. In any case, there's the opportunity for ham band
contacts with the HF station on 80 CW and 20 meter CW and SSB.

Alexanderson and the history of these amazing transmitters are at:

Additional information about these alternators as they were employed by RCA
in the USA is at:

The RCA machines were said to have developed 700 AMPS or RF into the
antenna. Not exactly QRP.
