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!
