Hearing S21CRO (Bangladesh) First Time on Space Station!

Today at 8.19 pm, there was a pass of International Space Station of 19 degree maximum elevation, passing from North West to South East. Looking at the pass direction on N2YO.COM, I thought that there is a chance of hearing Bangladesh station as the pass was nearly midway between the two regions. I kept my Moxon Yagi pointed North East to maximize the chance of hearing stations from Bangladesh. Just as I had expected, the moment I started picking up signals from the Space Station, it was S21CRO! I have not heard stations from Bangladesh on Space Station so far, though my VU friends in Central and North India have been able to work them. Soon after I heard VU2MZT calling him back a couple of times. But I could not hear the reply from S21CRO. I try similar passes in future and see if I can work that station.

Here is a short audio recording from the pass.
