Last weekend I followed the Sandringham School GB1SAN, as they made their contact with Tim Peak on the International Space Station GB1SS. This contact even got the attention of the BBC who made full report on it.
It reminds me of an article I read some time ago from the same AMSAT-UK how you can make your own ISS contact via APRS. Then I did put it on my wish list but forget about it.
When I was watching the report of Jessica Leigh M6LPJ and others it triggered my memory.

How cool would it be to succeed in making a APRS-contact with the ISS with just my current setup? If I understand it correctly, it must be possible to reach the ISS with just your average vertical for 2 meters. I do own a Diamond X-200N. And my Kenwood TM-D710 has all the APRS-capabilities on board to make the contact. On of these days I will pick a pass-over of the ISS and try to make a contact. Of course I will report on it here!
