Difficult RX of ISS

Hello everyone,

Does anyone heard Thomas Pesquet talking on the 5th may at 9H58 UTC?

I was making a demonstration of ISS reception with a group of 130 students in a school near Valenciennes, at 40km from Lillers, but even with a directive antenna we nearly heard nothing.
We noticed for a few second a little voice in the far background of QRM and signal were extremely low.

Can anyone give me some more information about what happened? I would love to be able to give some explanation to the students.

On the movies of the contact in Lillers, it is the same, the signal were very low and hard to understand.

It is a bit amazing while two weeks ago, at nearly same elevation scale, ISS signal was very strong and the audio very clear; as usual with ISS.

Thank you!

Columbus radio

What you experienced is the problem we have encountered with the radio in the Columbus module. That radio has one output setting of 5 watts. It also has a very long coaxial cable run outside the ISS. We never seem to get as good a signal out from that radio (hence the work to get a replacement). Most folks find that they need significantly more antenna gain to hear COL than the SM radio which has a max output of 45 watts.
