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:

Ofcom Consultation: Improving spectrum access for Wi-Fi

Ofcom Consultation: Improving spectrum access for Wi-Fi

5840 MHz UNITEC-1 Venus orbiter

5840 MHz UNITEC-1 Venus orbiter

Ofcom wishes to boost the use of Wi-Fi in Amateur Radio spectrum at 5725-5850 MHz.

The Amateur Satellite Service weak-signal downlink band, 5830-5850 MHz, is used by amateur payloads on Deep-Space and Interplanetary spacecraft as well as by satellites in Low Earth Orbit (LEO). Increased use of Wi-Fi across these frequencies would obliterate the weak amateur satellite signals.

Ofcom propose to remove the Dynamic Frequency Selection (DFS) requirements from Wi-Fi channels in 5725-5850 MHz. They also propose to make 5925-6425 MHz available for Wi-Fi.

The consultation closes on March 20, 2020.

Qarman beacon telemetry information released

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.

Beijing’s draft ham radio regulations raise concerns

Beijing’s draft ham radio regulations raise concerns

Ministry of Industry and Information Technology

Ministry of Industry and Information Technology

ARRL reports on Beijing’s draft Measures for the Administration of Amateur Radio Stations which appear to threaten 136 kHz and most amateur bands above 146 MHz.

ARRL say:

Lide Zhang, BI8CKU, told ARRL that the proposal would prohibit amateur operation on the 2200-meter band as well as on 146 – 148 MHz, 1260 – 1300 MHz, 3400 – 3500 MHz, 5650 – 5725 MHz, and all bands above 10 GHz.

Radio communications engineer and Chinese Amateur Satellite Group (CAMSAT) CEO Alan Kung, BA1DU, told ARRL that government efforts to eliminate some amateur bands are nothing new, but proposals that have been aired for a while now are on the regulatory agency’s schedule. Kung said he does not anticipate that all of the bands proposed will be taken away, but he conceded that the climate will “undoubtedly” become increasingly more dangerous for China’s amateur radio community.

A translation of the draft proposal says:

“Note 1: Unless otherwise specified, 135.7-137.8kHz, 146-148MHz, 1240-1260MHz, 1260-1300MHz, 3400-3500MHz, 5650-5725MHz, 10-10.4 GHz, 79-81GHz, 122.25-123GHz, 136-141GHz, 241-248GHz frequency The band frequency shall not be used for amateur services in the territory of the People’s Republic of China.”
