1:44 MFSK32: Program preview (now)
2:52 MFSK32: Text at 1500 Hz and simultaneous image at 2100 Hz*
7:33 MFSK64: Greener electronics to reduce e-waste
12:25 MFSK64: This week's images*
28:22 MFSK32: Closing announcements
* with image(s)

On today's Shortwave Radiogram, we will experiment with
transmitting two streams of MFSK32 simultaneously. One stream
will be text about the red squirrels at the Yorkshire Arboretum
in England. The other stram will be an MFSK32 image of a red
squirrel.
You can decode both streams simultaneously by running two
instances of Fldigi. On one instance, the RxID should be on (as
normal for most listeners). The RSID will switch the mode to
MFSK32 (it should be there already) and the audio frequency to
somewhere near 1500. On the other instance of Fldigi, turn the
RxID off. Manually switch the mode to MFSK32 (if not there
already) and the center audio frequency to 2100 Hz. A tone before
the picture is transmitted will help you fine tune to the
specific audio frequency. If all goes well, you will see the text
and the image decode simultaneously.
The alternative method is to record this edition of Shortwave
Radiogram. Decode the text at (or near) 1500 Hz "live" with the
RxID on. Later, from your recording, decode the image with the
RxID off and the center audio frequency set near 2100 Hz, guided
by the tone before the picture is transmitted.
To avoid clipping, mixing products, and audio harmonics, the
level of the combined MFSK32 streams was reduced by about 3 dB.
The decode of this combined MFSK32 signal might not be as robust
as from our usual single MFSK32 stream.
Our experiment begins in a few seconds ...

Greener electronics being developed to reduce unsustainably high
levels of e-waste
by Michael Allen
June 14, 2024
Greener sensors, circuit boards and other electronic devices are
being developed by EU researchers to reduce unsustainably high
levels of e-waste.
To develop eco-friendly electronics such as sensors and circuit
boards, Dr. Valerio Beni is following the paper trail—literally.
An expert in green chemistry at Swedish research institute RISE,
Beni has switched his focus to wood from pulp in a bid to make
consumer electronic devices that have no carbon footprint and are
easier to recycle.
In the woodwork
He and his colleagues discovered that producing pulp and turning
it into paper for a new generation of electronics required
burning too much energy for the effort to be as environmentally
friendly as they had hoped.
"So we thought, why don't we take a step back and go to the
initial material for making paper?" said Beni. "That is wood."
He leads a research project to explore ways to make consumer
electronics with wood-based materials.
Called HyPELignum, the project runs for four years through
September 2026 and brings together research institutes, a
university and industry representatives from Austria, the
Netherlands, Slovenia and Spain.
The life cycles of current electronics are unsustainable. In
addition to the energy and raw materials needed for production,
the gadgets result in mountains of waste once they get discarded.
In 2022, the world generated a record 62 billion metric tons of
e-waste—or 7.8 kilograms per person—with Europe producing 17.6
billion metric tons, more than any other region, according to
United Nations data.
That worldwide mountain has almost doubled from 34 billion metric
tons in 2010 and is projected to increase to 82 billion metric
tons by 2030.
In addition to growing fast, e-waste is complex to manage,
according to the UN. In 2022, only about a fifth of global
e-waste was recycled—although Europe fared better by recycling
around 43%.
Better boards
Circuit boards are the main component of e-waste.
As much as 60% of the environmental impact of electronics is
caused by a device's circuit board, according to Beni.
The boards are a layered matrix of materials—usually resins,
plastics and copper, which are hard to recycle. They're etched to
imprint metal circuits, onto which electronic components can be
soldered.
As an alternative, the HyPELignum team is developing two types of
wooden circuit board.
One is made of thin layers of wood, a bit like plywood. The other
is constructed from cellulose fibers extracted from wood and wood
waste.
"The idea is to try and replace some of the high carbon-intensive
materials in electronics with low carbon-intensive material,"
Beni said.
The circuits are printed—rather than etched—onto the wooden
boards using conductive metal inks developed by the project.
These inks also contain cellulose and bio-based plastics produced
from wood.
At the end of their life, the wooden boards should be easier to
recycle than traditional circuit boards. It might even be
possible to compost them.
New layers
A key challenge with recycling electronics is separating the
components from the circuit boards.
To tackle this, the HyPELignum researchers are developing
thermally and chemically degradable layers that can be placed
between the wood and the printed circuits.
When these are destroyed at the end of a product's life, the
circuits and electrical components fall off the wood. The wooden
board and the mainly metal circuit and components can then be
sent to different recycling streams.
Furthermore, the degradable layers are also derived from wood.
The project has been producing them from lignin extracted from
wood waste.
Such "green chemistry" emits much less carbon dioxide (CO2) by
featuring biogenic materials that can be renewed rather than
fossil oil, according to Beni.
"Wood and biogenic materials are more or less zero in terms of
CO2 impact," he said. "They absorb CO2 to grow and then they
release the same CO2 when used."
More and more
The global population's ever-increasing appetite for digital
devices is driving the need for greener versions, according to
Dr. Corne Rentrop, an expert in electronics and sustainable
production at Dutch research organization TNO.
"We want more data, we want more connectivity, we want to have
internet everywhere, so the amount of electronics needed to equip
that is growing constantly," Rentrop said.
At the same time, the lifetime of electronics is decreasing.
"If you look at your electronic devices, they last for four to
five years," Rentrop said. "That is basically it."
He leads a separate project to reduce the carbon footprint of
electronic-device production and improve recycling.
Called ECOTRON, it runs for four years through August 2026 and
has a range of participants from Belgium, the Czech Republic,
Finland, France, Italy, the Netherlands and Spain.
Flexible films
Like its HyPELignum counterpart, the ECOTRON team is seeking to
replace traditional circuit boards with ones made from renewable
materials.
"We can be more sustainable because the process requires less
energy than producing standard circuit boards," Rentrop said.
But instead of wood, he and his colleagues are creating flexible
films from materials like bio-based plastics and paper.
At the end of their life, bioplastic boards could be melted and
recycled—and maybe even composted.
"Compostable electronics would be fantastic," Rentrop said.
"Paper is of course a compostable material, but the inks and the
electrical components are not."
To overcome this hurdle, the project is developing reversible
interconnects that can be triggered to release the electrical
components.
