ARISS Responds to the COVID-19 Pandemic

In light of the recent COVID-19 pandemic, the ARISS team is working=20
to transform its activities for the health and safety of our=20
students, host educational institutions and its team.  It has=20
instituted an immediate response effort followed by a more strategic,=20
longer term initiative to protect all.  ARISS leadership, working=20
with a physician on the team, is carefully reviewing all of its=20
procedures in light of the evolving COVID-19 recommendation. ARISS=20
will continue to monitor the local and global situations and will=20
modify its local and global planning as these situations change.=20

ARISS has two primary initiatives underway.  One is to develop=20
=93virtual school=94 contacts to link each student in their home through =

its telebridge stations.  The other is to plan SSTV (picture=20
downlink) sessions during which pictures from ISS can be received by=20
all in their homes.

For further information on the ARISS plan, see:=20

New TQSL Version Provides Better LoTW Rover Support

The latest version of TrustedQSL (TQSL), version 2.5.2, offers=20
improved Logbook of The World (LoTW) support for operations from=20
several locations, as well as the ability to detect uploads that=20
contain incorrect location data.=20

The primary new feature in TQSL 2.5.2 allows logging programs, in=20
conjunction with TQSL, to avoid incorrect contact uploads, while=20
adding mechanisms to allow easy uploading of logs for roving=20
stations. LoTW had required rovers to identify each location used=20
as a separate location in TQSL. The new version of TQSL allows these=20
operations to be handled much more smoothly by using information from=20
the station=92s logging program.

When a log is signed by TQSL, the station details =97 call Sign, DXCC=20
entity, grid square, and other location details provided by the=20
selected station location (and call sign certificate) =97 are compared=20
with the details in the log. If the US state and station location in=20
a log do not agree, TQSL 2.5.2 will reject the contact, detecting=20
errors in instances when an incorrect station location has been=20

This feature will necessitate changes in many logging programs,=20
because it requires that the log provide station details previously=20
not used by TQSL. Once a logging program supplies these (MY_STATE,=20
MY_DXCC, MY_CQ_ZONE, etc.), then TQSL will validate them against the=20
log. Currently, Cabrillo logs use the CALLSIGN field to verify that=20
the contacts are for the correct call sign.

Optionally, a station performing roaming operations (e.g., from=20
multiple grid squares) can choose to have TQSL assume that the log is=20
correct. When call sign or home station are provided with the log,=20
TQSL will automatically update the details on the upload. Select=20
=93Override Station Location with QTH Details from your Log=94 on the=20
=93Log Handling=94 preference page to enable this feature.

This release also includes an update to the most recent TQSL=20
configuration file.

AMSAT-EA Registering SanoSat-1 for AMSAT Nepal

The Union of Spanish Amateur Radio Operators' satellite group,=20
AMSAT-EA, is registering with IARU and the ITU the AMSAT Nepal=20
satellite SanoSat-1.  This is being done due to the difficulty of=20
carrying out this procedure in the Asian country. This is a one-off=20
collaboration which will allow said satellite to fly under the=20
Spanish flag.  It should be launched jointly with the AMSAT-EA=20
EASAT-2 and Hades satellites possibly with SpaceX later this year.

SanoSat-1 is a 5cm/side pocketQube 1P designed and developed=20
affordably for the hobbyist community by using readily available=20
commercial of-the-shelf components (COTS).

The SanoSat-1 satellite integrates a gamma radiation sensor as a=20
payload. Its main mission will be to measure space radiation while=20
orbiting, and periodically transmit its level to Earth using RTTY-FSK=20
modulation. All radio amateurs will be able to receive and decode=20
radiation measurement data.

The secondary mission of the SanoSat-1 satellite is also to=20
demonstrate the storage and forwarding concept which will be useful=20
in remote disaster-prone locations. The satellite will collect=20
data from ground sensors, store it on board and transmit it to=20
Earth's main station. The design and kit for the ground sensors will=20
be made available to the general public.

One of AMSAT Nepal's goals is to encourage more people to join the=20
group of radio amateurs by receiving data from SanoSat-1 which will=20
also transmit a CW beacon with its internal status.

Another activity scheduled to promote radio amateurs and satellite=20
technology to science and technology students around the world is the=20
organization of hands-on workshops on the construction of=20
pico-satellites and ground stations. There will be an opportunity to=20
build an affordable open source ground station (SatNOGS) and a=20
dedicated GFSK receiver ground station to receive the data.  The=20
design of the satellite itself will be open source as well.=20

ESA and LibreSpace Report: SDR's for Small Satellites

The European Space Agency Libre Space Foundation has published a=20
paper comparing many common software defined radios (SDR's). The=20
devices they examined are:

- RTS-SDR v3
- Airspy Mini
- SDRPlay RSPduo
- LimeSDR Mini
- BladeRF 2.0 Micro
- Ettus USRP B210
- Pluto SDR

The report looked at several bands of interest, but not the HF bands=20
=97 not surprising considering that some of the devices can=92t even=20
operate on HF. They did examine VHF, UHF, L band, S band, and C band=20
performance. Some of the SDR's have transmit capabilities, and for=20
those devices, they tested the transmit function as well as receive.

The review isn=92t just subjective. It calculates noise figures and=20
dynamic range, along with other technical parameters. It also=20
includes GNURadio flowgraphs for their test setups, which would be a=20
place to start if one wanted to do these kinds of measurements=20

Towards the end of the 134 page report is an assessment of SDR=20
software and how the boards are supported. There was no clear winner=20
or loser although the report did mention how SDRPlay=92s closed source=20
limited software support in some applications.

Brazil Holds 430 and 1240 MHz Hearing

A public hearing is being held in Brazil concerning both the 430 MHz=20
and the 1240 MHz Amateur Radio bands.

On March 23, 2020 the National Telecommunications Agency, ANATEL,=20
published a Public Consultation proposal number 14/2020 on technical=20
and operational requirements for the use of the frequency bands from=20
430 MHz to 440 MHz and from 1240 MHz to 1300 MHz by stations of the=20
Private Limited Service (SLP) for radiolocation applications.

The national amateur radio society LABRE says =93The Radio Amateur=20
community is concerned about the possible occurrence of interference,=20
especially in the 70 cm band.=94

+ First Transatlantic Contact on 70 Centimeters Reported

History appears to have been made on April 7, when AMSAT member=20
Burt Demarcq, FG8OJ and an operator at=20
D4VHF in Cape Verde off the African Coast and , on=20
Guadeloupe in the Caribbean completed a contact on 70 centimeters=20
using FT8 =97 a distance of 3,867 kilometers (2,398 miles). This would=20
mark the first transatlantic contact on that band that did not=20
involve satellites or moonbounce. The most likely mode of propagation=20
was marine ducting, with the signal being trapped close to the ocean=20

One day earlier, 9Y4D in Trinidad copied D4VHF over a distance of=20
4,006 kilometers (2,484 miles), but no contact was made. D4VHF is the=20
VHF-UHF contest call sign of the Monteverde Contest Team (D4C).

Perhaps not coincidentally, FG8OJ was the first to span the Atlantic=20
