After my presentation at the AMSAT-DL symposium I got a lot off positive feedback and requests for more information and its availability. For the information part I update the product website, where you can also find the manual that explains the system in more detail and its use.

More samples will become available soon, still work in progress
Parts availability is nowadays another big challenge.
Wish you all a lot of fun on the QO-100 transponders,
