Shortwave Radiogram for the 6th of May 2019


I received the SWRadiogram show for this week and wanted to share my reception because it was surprisingly excellent for a broadcast coming from Florida all the way to the UK!

I decoded these broadcasts using my Xiaomi Mi A1 mobile running the Tivar app with the phone’s microphone next to the speaker of my Etón G3 connected to my 18m long copper wire.

I really enjoyed the number of pictures and also having music alongside the Olivia 64-2000. The music made all the difference for someone who has to listen to the digital sounds as they can be fatiguing!

I will now attempt to post the images and text from the Radiogram; wish me luck!

Annual Armed Forces Day Crossband Test Set for May 11

29 April 2019

The Army Military Auxiliary Radio System (MARS) will host the
traditional military/Amateur Radio communication tests to mark
the 68th annual Armed Forces Day (AFD) on Saturday, May 11. The
event is open to all radio amateurs. Armed Forces Day is May 18,
but the AFD Crossband Military-Amateur Radio event traditionally
takes place 1 week earlier in order to avoid conflicting with
Hamvention®. Complete information, including military stations,
modes, and frequencies, is available on the US Army MARS website

"For more than 50 years, military and amateur stations have taken
part in this event, which is only an exercise scenario, designed
to include hobbyist and government radio operators alike," the
event announcement said. "The AFD Crossband Test is a unique
opportunity to test two-way communications between military
communicators and radio stations in the Amateur Radio Service, as
authorized in 47 CFR 97.111. These tests provide opportunities
and challenges for radio operators to demonstrate individual
technical skills in a tightly-controlled exercise scenario that
does not impact any public or private communications."

During the event, military stations in various locations will
transmit on selected military frequencies and announce the
specific ham frequencies they are monitoring.

Military stations expected to be on the air for the event include
those in Arizona, Japan, Hawaii, Okinawa, Washington, DC (and
elsewhere in the contiguous states), the USS Midway, the USS
Yorktown, the USS Iowa, LST-325, the US Naval Academy in
Annapolis, and the Newport Naval Radio Station Museum in Rhode
Island. The MARSCOMM and MARSRADIO nationwide networks will have
multiple stations on the air across the continental US.

An AFD message will be transmitted utilizing the Military
Standard (MIL-STD) serial PSK waveform (M110) followed by MIL-STD
Wide Shift FSK (850 Hz RTTY), as described in MIL-STD 188-110A/B.
Technical information is available (2). The AFD message will also
be sent in CW and RTTY, as indicated on the full schedule (1).

World's first laser radio transmitter/receiver paves way for
ultra-high-speed Wi-Fi

David Szondy
29 April 2019

Researchers at the Harvard John A. Paulson School of Engineering
and Applied Sciences (SEAS) have, for the first time, used a
semiconductor laser to send and receive radio signals. The hybrid
electronic-photonic device uses a laser to extract and transmit
microwave signals, providing a data rate that may one day lead to
ultra-high-speed Wi-Fi.

Hearing Dean Martin singing "Volare" on the radio may not seem
that earthshaking, but when it's the first radio transmission and
reception using lasers, it's something a little special.
According to the team behind the new technology, the laser not
only emitted microwaves wirelessly, but also modulated them and
received outside radio signals.

Working on previous research by the team in 2017 and 2018, the
laser radio works by means of an infrared laser frequency comb. A
garden variety laser generates light at a single frequency, much
like a violin playing a precise note as opposed to a white noise
generator spewing out the whole spectrum of sound. In a frequency
comb, the laser produces multiple beams at multiple frequencies
that are evenly spaced apart like the teeth of a comb, hence the

In 2018, the SEAS team found that the light "teeth" of the laser
comb could be made to resonate against one another, causing the
electrons in the cavity of the laser to oscillate at microwave
frequencies in the radio band of the spectrum. In the top
electrode of the device, there's an etched slot that acts as a
dipole antenna, like the rabbit ears on an old-fashioned analog

By modulating the comb, the team was able to encode data on the
microwave emission. This was then transmitted by the antenna to
its reception point, where it was picked up by a horn antenna
before being filtered and decoded by a computer. In addition, the
laser technology could also receive radio signals, and the
laser's behavior could be controlled remotely using microwaves
from a second device.

"This all-in-one, integrated device, holds great promise for
wireless communication," says Marco Piccardo, a postdoctoral
fellow at SEAS. "While the dream of terahertz wireless
communication is still a ways away, this research provides a
clear roadmap showing how to get there."

The research was published in the Proceedings of the National
Academy of Sciences.

Irish Long Wave Station gets two year extension

28 April 2019

The Irish radio station RTE on 252 kHz is one of the few still
operating on the long wave band in Europe.

Although it was scheduled to close in June of 2019, it has now
been given a new lease of life with an upgrade to the
transmission mast.

It will now stay in service for a minimum of two more years.

The Irish diaspora in Britain are some of the main users of the
service and they had been lobbying for it to continue.
