They use same frequency 437.375 MHz and transmit in the order of BHUTAN-1, MAYA-1 and UiTMSat-1. Each CubeSat also has an APRS digipeater on 145.825 MHz.

Watch BIRDS-2 deployment live broadcast at https://www.youtube.com/watch?v=pwS5uE5RStw

Satellite      Country      ID             Call Sign

The live broadcast will open on 0915-1010z August 10. Deployment will be done around 0945z.

Initial operation plan is announced as following.
T=0  deployment form ISS
T+30  V/U antenna deployment
T+32  437.375MHz CW beacon start transmitting

So, CW beacon will start 1017z. The location is over Central Asia. Satellites go towards the east and pass through China, Japan, Pacific Ocean, South America, Africa and Europe. Check the orbit with ISS keps.

ISS SSTV activation July 30-31

The Russian cosmonauts on the International Space Station are expected to activate amateur radio Slow Scan Television (SSTV) transmissions on 145.800 MHz FM during Monday and Tuesday, July 30-31.

The Inter-MAI-75 SSTV experiment should be active on:
• Monday, July 30 from 16:00-19:30 UT
• Tuesday, July 31 from 13:25-19:15 UT

The SSTV images will be transmitted on 145.800 MHz FM using the Kenwood TM-D710 transceiver located in the Russian ISS Service module. It is expected they will use the PD-120 SSTV format.

Note the ISS transmissions use the 5 kHz deviation FM standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try using the wider filter. Handheld transceivers generally have a single wide filter fitted as standard and you should get good results outdoors using just a 1/4 wave whip antenna.

You can receive the SSTV transmissions by using an Online Radio (WebSDR) and the MMSSTV software:
• Listen to the ISS when it is in range of London with the SUWS WebSDR http://farnham-sdr.com/
• Listen to the ISS when it is over Russia with the R4UAB WebSDR

CubeSats to deploy from ISS July 13

Masa JN1GKZ reports JAXA has announced that nine CubeSats will deploy from the International Space Station on Friday, July 13.

The nine CubeSats are RainCube, Radix, CubeRRT, HaloSat, TEMPEST-D, EnduroSat AD, EQUISat, MemSat and RadSat-g.

EnduroSat AD, EQUISat and MemSat will operate in the amateur bands. The IARU Amateur Satellite Frequency Coordination Status pages show these frequencies:
• EnduroSat AD 437.050MHz CW, GFSK 9k6
• EQUISat 435.550MHz CW, FSK 9k6
• MemSat 437.350MHz BPSK 9k6

Happy chasing!

ARISS Russia is planning a special Slow Scan Television (SSTV) event  from the International Space Station Station starting around 09:00 GMT on Friday, June 29.

It was originally planned to finish at 18:30 GMT on Sunday, July 1 but as of July 7 SSTV transmissions were continuing. The equipment will be required for a school contact on July 13 so SSTV transmission may continue until then.

Supporting this event is a computer on the ISS Russian Segment, which stores images that are then transmitted to Earth using amateur radio, specifically the onboard Kenwood TM-D710E transceiver.

These images will commemorate the various satellites that were hand-deployed from the ISS. These will include the first satellite deployment from ISS: Suitsat-1/Radioskaf-1 which was developed by ARISS and deployed in February 2006.

The transmissions will be made on 145.800 MHz FM using the PD-120 SSTV mode.

Note the ISS transmissions use the 5 kHz deviation FM standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try using the wider filter. Handheld transceivers generally have a single wide filter fitted as standard and you should get good results outdoors using just a 1/4 wave whip antenna.

The ISS Fan Club site will show you when the space station is in range http://www.issfanclub.com/

Post your images on the ARISS-SSTV gallery at http://www.spaceflightsoftware.com/ARISS_SSTV/

If you don’t have an amateur radio receiver you can still listen to the ISS by using an Online Radio, also known as a WebSDR. Select a Frequency of 145800.0 kHz and Mode FM:
• Farnham WebSDR when ISS is in range of London http://farnham-sdr.com/
• R4UAB WebSDR when ISS is over Russia

Please note that the event is 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:

ARISS-Russia FM transmissions from Space Station

A Tanusha CubeSat

On June 20 and 21, the Tanusha satellites will be connected to an antenna on the ISS Russian Service Module and transmit voice messages on 437.050 MHz FM with 145.800 MHz FM relay.

The AMSAT-NA website says:

ARISS-Russia, in collaboration with the Southwest State University in Kursk, Russia, are developing a series of educational CubeSat satellites called Tanusha.

Two Tanusha CubeSats were developed by students at Southwest State University and were hand-deployed by cosmonauts during an August 2017 extravehicular activity. These two CubeSats are performing cluster flight experiments through communications links.

A second set of CubeSats, Tanusha 3 & 4 were launched earlier this year and are currently on-board ISS. Tanusha 3 & 4 are planned to be hand deployed by Cosmonauts in August. They will perform even more comprehensive cluster flight objectives than Tanusha 1 & 2.

On June 20, Tanusha 3 will be connected to one of the ARISS Service Module antennas and will transmit from 0730-1200 UTC on 437.05 MHz. These FM transmissions will include greetings from students in several languages, including Russian, English, Spanish and Chinese.

On June 21, Tanusha 4 will be connected to one of the ARISS Service Module antennas and will transmit from 0730-1200 UTC on the same frequency: 437.050 MHz.

The ARISS-Russia team plan to also retransmit these signals on the standard ARISS 2-meter downlink, 145.80 MHz using the JVC Kenwood D700 radio that is still on-board ISS. All are invited to listen to the CubeSats from ISS on 437.050 and/or 145.800 MHz FM.

Note: the Doppler shift for the 437.050 MHz signal will be +/-10 kHz.
