> Brian Justin, WA1ZMS, of Forest, Virginia, will once again put his
> 600-meter experimental station on the air for a Christmas Eve
> commemorative transmission. The transmissions from WI2XLQ on 486 kHz
> will mark the 110th anniversary of Reginald Fessenden's first audio
> broadcast on the airwaves.
>
> Historic accounts say Fessenden played the violin - or a recording
> of violin music - and read a brief Bible verse. It's been reported
> that other radio experimenters and shipboard operators who heard
> Fessenden's broadcast were astounded.

> Justin will use a MOPA-design transmitter built largely with vintage
> parts to replicate early vacuum-tube equipment; not a
> Fessenden-period transmitter, it uses a UV-202 tube for the power
> amplifier. He will conduct a run-up to the event starting at around
> mid-day Eastern Time on Friday, December 23. The "official"
> Christmas event will begin on Christmas Eve, Saturday, December 24,
> at 0001 UTC (the evening of December 23 in US time zones) and will
> continue for at least 24 hours. Justin plans to repeat the
> commemorative transmissions on New Year's Eve and on New Year's Day.

> For his transmitter in 1906, Fessenden used an AC alternator
> modulated by placing carbon microphones in series with the antenna
> feed line. Justin's homebuilt station is slightly more modern, based
> on a 1921 vacuum tube master oscillator power amplifier (MOPA)
> design. The transmitter also uses Heising AM modulation, developed
> by Raymond Heising during World War I.
>
> Justin's WI2XLQ on-air operations coincide with dates in early radio
> history as a way to recognize and honor some of the earliest
> wireless pioneers and their achievements. Send listener reports
> directly to Brian Justin, WA1ZMS, via email at, wa1zms at arrl.net
