Now an annual Christmas tradition, Brian Justin (WA1ZMS) will put his longwave experimental station WI2XLQ on the air to commemorate the anniversary of Reginald Fessenden’s first audio transmission.

As in years past, he will be conducting the Fessenden transmission on Christmas Eve, as well as New Year’s Eve. The plan is to start each day around 1800z and run for 24 hours.

Listener reports may be sent to Brian Justin, WA1ZMS, at his QRZ.com address.

Experimental Station will Recreate 1906 Fessenden Transmissions

Experimental station WI2XLQ will be on the air on 486 kHz AM for the Reginald Fessenden commemorative transmission. Brian Justin, WA1ZMS, is the licensee. He will transmit for 24 hours starting at 2000 UTC on December 24, with a repeat transmission starting at 2000 UTC on December 31. Justin will use a homebrew 1921-era MOPA exciter with Heising modulation, followed by a modern 500-W linear. The transmission will be the same as in past years — two violin pieces that Fessenden claims to have played as one of the very first voice transmissions from his Brant Rock, Massachusetts, radio lab site. “While doubt remains that such a transmission ever took place, Fessenden did perform some crude voice transmissions over a few miles distance in early December near Washington, DC, as a demonstration for the US Navy,” Justin said. “So, perhaps some credit is due Fessenden for his efforts to transmit the human voice in an era of spark transmissions.”

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.

Our radiostation ( the radiovan above) will be on the air with many different type of programs, mostly in Swedish. The transmitter will have a power of 250 W (ERP) on 1593 kHz and the antenna is located on a high hill near lake Vättern. In the evening of May 5th we will start tests. There will be station identifications in English, too.

The official start will be May 6th at 1900 UTC and the programs will be running until 1100 UTC on Sunday noon

On the 7th there will be a program dedicated to the local SR P4 Radio Jönköping that celebrates its 40th year of broadcasting. this year. This program starts at 1000 UTC and will be in Swedish. Until the station signs off at 1100 UTC.

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!

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!
