[CW] The First CW Transmitter was an Electric Alternator! The Sound of Grimeton Radio SAQ

[D.J.J. Ring, Jr.]

This list is the CW list, and CW means Continuous Wave, which was different
than the first type of radio which was spark which was Damped Waves, called
Type B Modulation, while Continuous Wave was called CW modulation, or type
A1 modulation.  https://en.wikipedia.org/wiki/Damped_wave

So we celebrate a bit of history with the first CW transmitter, the
Alexanderson Alternator.

I asked Lars Kålland, SM6NM who runs the Grimeton Radio / SAQ transmissions
from the last remaining operational Alexanderson Alternator for a recording
of the last transmission from SAQ.  He gave me one and I'd like to share it
with you.
