We look forward to continuing to provide you with the most pertinent
amateur satellite news and information in the coming year in a new and
updated format beginning in January.

LAST CALL for 2023 AMSAT President's Club Coins!

The year is almost over and, when it is,
the 2023 coins will no longer be available.

To commemorate the 40th anniversary of its launch
on June 16, 1983, this year's coin features
an image of AMSAT-OSCAR 10.

HADES-D Designated SO-121, Active For General Use

HADES-D satellite has been commissioned. After a trial period in which its
behavior has been tested at the radioelectric, systems, and energy
performance levels, the FM repeater is left active for general use.

At the request of AMSAT-EA, AMSAT has designated HADES-D as Spain-OSCAR 121
(SO-121). AMSAT congratulates AMSAT-EA, thanks them for their contribution
to the amateur satellite community, and wishes them continued success on
this and future projects.

The repeater works with FM/FSK (MSK144 has been tested too) with an uplink
frequency of 145,875 MHz and a downlink frequency of 436,663.5 MHz (a bit
lower than the 436.666 MHz expected). We have been able to verify that the
modulation is more appropriate by narrowing the bandwidth, so it is
recommended to use NFM in those devices allowing it.

AMSAT-EA is drafting a use and operation manual, which will be published
shortly and which will indicate in detail some of the characteristics of
the satellite and its working modes. Although it is not definitive,
Amsat-EA is considering some special operating options such as reserving a
day of the week exclusively for digital communications following the
example we know with the AO-92.

Finally, please, remember that, as far as we know, HADES-D is the first
satellite with FM repeater service mounted on a pocketqube platform. This
standard is the smallest in terms of normalized satellite sizes. HADES-D
size is 8x5x5 cm. Its panel surface and battery size are much smaller than
the rest of the satellite repeaters in use, so HADES-D is not comparable to
most of them either in radiated power or signal strength. HADES-D should be
considered a QRP satellite.
