WI2XLQ: Brian Justin’s annual longwave broadcast

The Canadian inventor, experimenter, and entrepreneur Reginald Fessenden has been credited as the inventor of radiotelephony. Fessenden claimed to have made his first voice — and music — broadcast on Christmas Eve in 1906 from Brant Rock, Massachusetts, although his account is disputed. As he has done each December for the past few years, Brian Justin, WA1ZMS, of Forest, Virginia, will transmit a program on 486 kHz, under authority of his FCC Part 5 Experimental License WI2XLQ ito commemorate Fessenden’s accomplishments.

Justin will transmit for at least 24 hours starting at around 2000 UTC on December 24, with a repeat transmission on New Year’s Eve likely, “keeping in step with what Fessenden was reported to have done on both nights in 1906,” Justin explained.Fessenden’s transmitter was most likely a high-speed “dynamo” or alternator — a predecessor to the later Alexanderson alternator — modulated by placing a carbon microphone in series with the antenna feed line to create an amplitude modulated signal. Fessenden a few years earlier had limited success making voice transmissions using a rotary spark gap transmitter. Fessenden fed his signal into a substantial antenna system erected in Brant Rock for his experiments. Accounts say on Christmas Eve 1906, he transmitted recordings of two pieces of music and read a verse from the bible.

Justin will use somewhat more modern equipment — a home-brew master oscillator, power amplifier (MOPA) transmitter based on a classic design from the early 1920s. It uses a UV-201 oscillator tube driving a VT-25 tube — a modern equivalent to a UV-202 — to generate “a few watts” on 486 kHz. His modulator consists of another VT-25, which uses a large inductor in the RF amplifier’s plate supply to serve as a Heising modulator. The audio program comes from a laptop computer.

“Heising modulation was used in World War I as an easy way to achieve AM in rigs such as those used in aircraft,” Justin said. “My particular Heising modulator can deliver only around 60% modulation, so an audio processor is used to help boost the average volume level ahead of the modulator tube.”

Justin uses far more modern technology to boost “the few watts” of modulated RF to drive a modified Hafler 9505 solid-state 500-W audio amplifier. “The idea for the amp came from W1TAG and W1VD,” he said, “and information on using such an amp on the 630 and 2200-meter ham bands can be found on the web.” After a multi-pole low-pass filter, the carrier output is 150 W.

Justin’s antenna is a Marconi T, crafted from a 160-meter dipole some 60 feet above ground and fed with open-wire line, which is shorted at the transmitter end. A homebrew variometer — constructed from 14-gauge wire wound on a piece of 4-inch diameter PVC pipe — is placed in series to resonate the antenna, which is fed against an extensive ground system. “Most of the RF is lost due to the ohmic losses of the ground system, but at least 15 W ERP is possible, depending on the dampness of the soil. Damp soil helps lower the ground losses,” Justin said.

Video: Tour of RNW operations van and interview with Niels Zack

ShortwaveService has uploaded the following video (to YouTube) which features the RNW Operations Van used in the recent 70th anniversary broadcast.

The video includes a tour of the van, the setup used in the 70th anniversary broadcast and an extended interview with Niels Zack, who restored the operations van:

I listened to at least an hour of the Saturday broadcast via the U Twente WebSDR. Sadly, I just discovered the audio dropped about 2 minutes into my recording.

Post readers: Anyone else listen to, record or simply log this anniversary broadcast? Please comment!

April 15: RNW returns for broadcast from original news van

Schagen Auto Museum

Many thanks to SWLing Post contributor, Gerard Koopal, who shares the following:

Below an article about the return of RNW Netherlands out of a 1958 truck on april 15.
Although i suppose you can’t read German, the times and freq’s should be clear.


… zwar nur für einen Tag aber immerhin:

Am 15. April, also diesen Samstag, gibt es eine Sondersendung aus dem
Automuseum Schagen im Norden der Niederlande. Die ehemaligen Mitarbeiter
Dick Klees, Hans Hogendoorn, Pieter Damave und Ruud Poeze werden aus einem
originalen Ü-Wagen des RNW aus dem Jahr 1958 eine 7-stündige Live-Sendung fahren.

Die Sendung wird über Stream, Mittelwelle van Radio Paradijs auf 1584, 1332 und 1224 kHz und im DAB Kanal 8A in Randstad ausgestrahlt.

Ach ja: Kurzwelle gibt’s auch, von diesen bösen Menschen beim
Schortwääävsörvizzz:

… auf 3985 kHz zw. 11-18 CEST
… auf 6005 kHz zw. 11-15 CEST
… auf 7310 kHz zw. 11-12 und 16-17 CEST
… auf 15560 kHz zw. 14-17 CEST

Kontakt zur Crew während der Sendung per e-Mail Wereldomroep70@hotmail.com

Many thanks, Gerard! I found that Google Translate did a fairly good job translating the Dutch article into English–click here to read.

Keep in mind that CEST is UTC +2 hours. Broadcasts will start at 1300 UTC 9:00 UTC (thanks for the correction, Christian!).

I love the sound of this special event. I’ll certainly be listening and, hopefully, recording!

Fessenden Christmas Eve Commemorative Transmissions

Embedded image permalink

This  was reported in the ARRL Newsletter:

Brian Justin, WA1ZMS, will again put his 600 meter Experimental Station WG2XFQ on the air on for a Christmas Eve commemorative transmission. WG2XFQ will transmit on 486 kHz from Forest, Virginia, to mark the 109th anniversary of Reginald Fessenden’s first audio transmission. Historic accounts say Fessenden played the violin — or a recording — 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 conduct a run-up to this year’s event starting at around mid-day Eastern Time on December 23. The “official” Christmas event will begin on December 24 at 0001 UTC (the evening of December 23 in US time zones) and will continue for at least 24 hours. Justin said he plans to repeat the commemorative transmissions on New Year’s Eve and on New Year’s Day.

Fessenden’s transmitter was 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. Listener reports are appreciated and may be sent directly to Brian Justin, WA1ZMS, at his QRZ.com address.

While I have not heard Brian’s transmission before, I have actually heard a transmission on the experimental frequencies between 465 – 515 kHz. I never expected to be able to hear anything due to extremely high local noise, but one night the propagation gods smiled upon me and the evening was exceptionally quiet. I listened on my Elad SDR receiver over and over to the Morse Code signal which was extremely weak, but mostly readable. I confirmed with Multipsk software, verifying I was indeed hearing one of the experimental stations out of Connecticut.

For information regarding the 500 KC experimental project you can follow this link.

Why not give a listen? You just might be surprised like I was to hear something on this band, and you could add a little Christmas Eve radio memory to your collection!!             73, Robert
