Received 20:10 – 20:18 on April 13 (Salut 6)

Received 11:09 – 11:20 on April 14 (participating cosmonauts).

In celebration of Cosmonautics Day the cosmonauts on the International Space Station (ISS) transmitted, using the ISS’s Kenwood TM-D710E transceiver, several images honoring the Interkosmos project . Dean (KV4RL) set up his Yaseu FT-857D transceiver connected to a laptop and assembled these images directly from the ISS as it passed overhead.
