Students at Sree Narayana Trust Higher Secondary School returned to the classroom during their holidays to receive amateur radio Slow Scan Television from the International Space Station.

The special ISS transmissions were made in July to commemorate the 40th anniversary of the Apollo-Soyuz mission.

The Deccan Chronicle newspaper reports that with the support of their teachers the students were able to decode the SSTV images on a frequency of 145.800 MHz FM.

The school has an amateur radio club, callsign VU2SQL, and the Principal is licenced radio amateur U.Jayan VU2JYU.

When ISS Ham Radio might be off

ARISS Amateur Radio on the International Space Station

Mike KC8YLD has posted some guidance as to when the Amateur Radio stations on the ISS would be turned off.

Current flight rules require all the ham radios to be off during an EVA. Technically, the VHF radios needs to be off for Russian EVAs and the UHF radio needs to be off for US EVAs.

For dockings and undockings, again the ISS operates under a flight rule that has the VHF/UHF radios off for Progress, Soyuz and ATV vehicle activity. Note that Cygnus, Dragon, HTV and formerly the Shuttle did not require the radios to be off.

For Ham TV, it will be off for any EVA. It needs to be off for ATV (the last one November) docking and undocking. It also has to be off when the Robotics arm is in close proximity.

The AMSAT-NL transponder on EO-79 is being activated to support the International Lighthouse and Lightship Weekend (ILLW).

On the AMSAT Bulletin Board Wouter PA3WEG posted:

We apologize for the short notice, this opportunity came along very last minute, and again we took it.

QB50p1 (EO-79) carries the FUNcube-3 400 mW inverting linear 435/145 MHz SSB/CW transponder provided by AMSAT-NL with support from AMSAT-UK.

• 435.035-435.065 MHz LSB Uplink
• 145.935-145.965 MHz USB Downlink

TLEs are NORAD # 40025, COSPAR designator 2014-033-R

Remember that the FUNcube family of transponders do not need much power to work them.

I will be operating at Scheveningen Lighthouse PA25SCH, NL0025

Thanks to the Von Karman Institute and Innovative Solution In Space for the opportunity to use the transponder.

Have FUN over the weekend!
