Gang,
As you probably know the traditional Christmas Eve transmission from The
Alexanderson alternator, SAQ, in Sweden has been cancelled. Here is an
easier challenge.
*Fessenden Commemorative Broadcast on 486 kHz *
Brian Justin, WA1ZMS, of Forest, Virginia, will once again
transmit a program in AM mode on 486 kHz, utilizing his Part 5
Experimental Service license WI2XLQ, to commemorate the Christmas Eve
1906 broadcast of voice and music by inventor Reginald Fessenden. Justin
plans to transmit for 24 hours or more, starting at around 1800 UTC
(noon CST) on December 24. Fessenden reportedly repeated his broadcast
on week later, but it is not known at this writing whether Brian plans
to do likewise.
Fessenden was working with an Alexanderson alternator of early
design. the output of which was modulated with a large carbon
microphone, on frequencies around 75-80 kHz. His Brant Rock,
Massachusetts station BO had already been copied in Scotland while
conducting voice tests earlier in the month.
Unlike Lee de Forest's work a few years later, Fessenden's focus
in 1906 was on ship-to-shore and transoceanic communication, which he
held to be a more important use of wireless than broadcasting. The lack
of contemporary documentation has led some to dispute his later
recollections of the event, but Westinghouse VP Sam Kintner accepted the
claim, as does modern radio scientist Jack Belrose.
Sounds like he's running 150-watts AM. Details Here

Spin up those BC-348's!
Merry Christmas
