I would like to post some autonomous algorithmic bidirectional radio search system production design approximation stuff here.
Please, you are welcome with any questions you may find of particular interest in this regard.
p.s. My apm 2.0 dates from 2011 early preorder and it's still in touch yet after all it has gone through.
Thank you, maintainers, testers, 3dr team as well as all people involved, that was and still is and no doubt will be lots of further fun.
