[Milsurplus] Alexanderson Transmission on Christmas Eve

[C.Whitaker]

de WB2CPN
I understand the Marion, MA, machine had a electromagnetic frequency
tripler between the alternator and the antenna system, and that the
on/off RTTY relay was in the primary antenna loading system.  That was the
relay that had a fan to minimize the arc.
Has any one plotted the path the radio wave would take from northern Europe
to here in middle USA?  How would the ionosphere react to a signal that 
low?
We did not use an RBA, but used a loop antenna and an associated converter
with a modified BC-779 at a receiver.  A Canadian company, Hinge, 
manufactured
all this, and their Hinge Pulse Detector which was the RTTY demod.  Thee 
testing
we did at Andrews and in Alaska used the Stoddard Aircraft receiver 
which was
designed for this sort of thing.  It used a one-meter loop.
Perhaps they could run it at another time, like national events in Sweden
or something.   73  Clete
