AMSAT Argentina drifting Buoy on 145.825 MHz APRS

AMSAT Argentina LU7AA drfiting BuoyOn Thursday, January 30 at 1400 GMT AMSAT Argentina will deploy drifting Buoy on South Atlantic Seas that aims to transmit APRS on the satellite packet frequency of 145.825 MHz. WSPR will also be transmitted.

AMSAT Argentina report:

The APRS beacon, callsign LU7AA-11, will initially be on Argentina’s APRS frequency of 144.930 MHz but will change frequency to 145.825 MHz so that it can be digipeated by the amateur packet radio satellites.

The WSPR beacon will run 900 mW on 14095.6 kHz with the call sign LU7AA.

Release will be 100 km offshore Mar del Plata coast, seeking east aiming currents/winds.

Objective: Sea currents tracking and HF/VHF/SAT QRPp propagation tests.

AMSAT Argentina, LU7AA, will appreciate WSPR stations receiving/reporting 20m.

Slow Scan TV from ISS January 30-31

ISS SSTV MAI-75 image 9/12 received by Chertsey Radio Club on Baofeng handheld

ISS SSTV image 9/12 received by Chertsey Radio Club on Baofeng handheld

Russian cosmonauts are expected to activate Slow Scan Television (SSTV) image transmissions on 145.800 MHz FM from the International Space Station on Thursday, January 30 and Friday, January 31 as part of the MAI-75 experiment.

The expected activation times are:
• Thursday, Jan 30 at 13:30 – 19:00 GMT
• Friday, Jan 31 at 15:00 -17:30 GMT

Note: The computer that supports this activity failed recently so a replacement is being used. It is unknown what impact this may have to the operations.

Transmissions will be made on 145.800 MHz FM (5 kHz deviation) in the SSTV mode PD-120. Once received, images can be posted and viewed by the public at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php

ISS SSTV uses a Kenwood TM D710E transceiver which is part of the amateur radio station located in the Russian ISS Service Module.

Please note that SSTV events are dependent on other activities, schedules and crew responsibilities on the ISS and subject to change at any time. You can check for updates regarding planned operation at:

Qarman beacon telemetry information released

QARMAN CubeSat

QARMAN CubeSat

QARMAN, a nano-satellite designed and built at VKI, was launched to the International Space Station on December 5, 2019. Deployed is expected to take place in the week of January 20, 2020.

QARMAN (Qubesat for Aerothermodynamic Research and Measurements on AblatioN) is the world’s first CubeSat designed to survive atmospheric re-entry. Work on it started in 2013 at the von Karman Institute for Fluid Dynamics (VKI).

The aim of the QARMAN mission is to demonstrate the usability of a CubeSat platform as an atmospheric entry vehicle. Spacecraft descending towards a planet with an atmosphere experience very harsh environment including extreme temperatures (several thousand degrees).

Information about Qarman’s 437.350 MHz 9600 bps GMSK AX.25 beacon has now been released by the team.
