Happy to hear VU2TUM on ARISS!
You just heard VU2TUM on the crossband repeater of International Space Station. I had kept my Moxon Yagi towards East, looking for some DX stations from the Eastern side. When the satellite was towards the North, I could hear VU2TUM. But my antenna was pointed almost 90 degrees away and my calls could not reach the satellite at that point of time. If only I had pointed my antenna to North instead of East, I could have a had a contact with VU2TUM at about 2000 km from here, which is as good as a DX!
