Seema talking to Tim Peake GB1SS

Pete Sipple M0PSX from Essex Ham will be giving a talk about the Tim Peake GB1SS amateur radio school contacts at the Southend Raspberry Jam on Saturday, August 20.

The talk about Tim Peake’s amateur radio educational outreach activity starts at 10:30. Other activities during the day include a talk on Tim Peake and the AstroPi at 11:30 and a Build a Radio Workshop at 12:00.

Southend Tech and Enterprise4Good are holding Southend Raspberry Jam #10 at the Hive Enterprise Centre in Southend, SS2 6EX. The event runs from 10am until 5pm and is free but advance booking is required, see

ISS SSTV on Baofeng Handheld

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

The Chertsey Radio Club demonstrated that you can receive pictures from Space using simple low-cost equipment such a Baofeng VHF handheld radio and a Lynx-7 Tablet.

On Monday, August 15, 2016 radio amateurs from Japan, India and countries as far west as Brazil successfully copied Slow Scan Television images transmitted on 145.800 MHz FM from the Russian amateur radio station located in the ISS Service Module.

The Russian Cosmonauts were using a Kenwood TM-D710 transceiver thought to be running about 25 watts output. It gave a good signal which could easily by copied on VHF handheld transceivers such as the popular Baofengs.

It expected there will be further SSTV transmissions on Tuesday, August 16. The ISS transmits 5 kHz deviation FM, if your transceiver has selectable FM filters you should select the wider filter for best results.

Receiving an ISS picture is a newsworthy event, if you’ve received part or all of an image why not tell your local newspaper and get some positive publicity for amateur radio

Amateur Radio BIRDS CubeSat Constellation

BIRDS CubeSat Engineering Model integration test

BIRDS CubeSat Engineering Model integration test

The BIRDS constellation, planned to deploy from the ISS in 2017, will consist of four 1U CubeSats (BIRD-B, BIRD-J, BIRD-G and BIRD-M). They are made of the exactly same design including the radio frequencies to be used and will be deployed together.

BIRDS CubeSat Project LogoThe main mission of the constellation is to do experiments on radio communication with a CubeSat constellation via a network of UHF/VHF amateur radio ground stations all over the world.

The challenge is to distinguish each satellite from the four satellites transmitting with the same frequency, hand over operation of a satellite from one ground station to another and assemble the satellite data, such as housekeeping telemetry, music and the Earth images, obtained at different ground stations.

Amateur radio enthusiasts are asked to join the network to assist in the data downlink and reconstruction of the patchy satellite data into one meaningful data. Orbit information and operational plan of each satellite will be made available to the amateur radio community in the world. Software to decode the satellite data will be also made available.

The respective amateur ground stations that can successfully decode the telemetry data, music and the Earth images, shall receive a QSL card from the BIRDS team. The data reconstructed by the effort of the amateur ground station network will be made public to share the sense of satisfaction and achievement.

BIRDS CubeSat NationsA particularly interesting mission of BIRDS project is the SNG mission that exchanges music via a digi-singer. It is an outreach-oriented mission. First, music in MIDI format is uploaded from ground. Then the MIDI file is processed on-board using a vocal synthesizer. Finally, the processed music is sent back to Earth using UHF antenna as voice FM data.

During organized events on space utilization with schools or general public, music could be heard using a common hand-held receiver and hand-made Yagi antenna positioned to track the satellite at each given pass over the region. This has a tremendous effect on awareness of radio communication among school children and general public, especially in the countries participating in the BIRDS project, Japan, Ghana, Mongolia, Nigeria and Bangladesh.

Proposing to use CW, 1k2 AFSK FM, audio FM and 9k6 GMSK downlinks. Planning a JAXA sponsored deployment from the ISS during 2017.

The ARRL reports Slow-scan television (SSTV) transmissions will be made from the International Space Station (ISS) on August 15-16, 2016.

The MAI-75 Experiment will transmit SSTV images on 145.800 MHz FM over the course of a few orbits as the space station passes over Moscow. Operators in Europe and South America will have the best chances to receive images. Operators along the US East Coast may have one chance on August 16.
