ISS crossband repeater: voice s21rc & vu3tyg
Last few months I was chasing the International Space Station and some other Satellite like AO-51. I was trying to use different modes of communication NASA approved for the ISS amateur radio setup. The cheap eggbeater antenna I home-brewed (made) and used to receive the SSTV image from the space station was showing its age, the physical shape of the antenna was not what it was when I fixed it on my rooftop over the water-tank, the electrical joints were corroded. I guess the polarization was changed as well due to the above problems, you will hear the fadeout of reception during the conversation.
This audio clip was a conversation made between me(S21RC from Dhaka, Bangladesh) and Nitin(VU3TYG from Bangalore, India) using the ISS Cross-band repeater.
