LO-19 (aka LUSAT) after 30 years in space is emitting day and night a strong carrier.
What is amazing that after over 2 millions charge/discharge cycles its vintage NI-CD batteries are still able to receive and hold charge.
It is known that Lithium based batteries usually halve charge capacity after +/- 400 cycles, probably you noticed that on your portable device. https://batteryuniversity.com/_img/content/lithium2.jpg
This is just a comment for future satellite plans if long duration is part of the objective.
