Very nice well written report.
I'm personally delighted with all the information provided, therefore I give you a thumbs up for it.
With all due respect I would like also to point out that in the FTA hobby no one is an "extra class" FTA licensee per say, because there is no such thing.
In most of the cases I dare to say that if to a FTA hobbyist a new LNB fails he or she will return it to the store and if it fails after some time of use you just trash it and buy a new one.
Again I encourage you to continue with the same devotion of HAM, but FTA is a different hobby.
FTA is more of an entry level hobby that requires a more basic set of skills for the hobbyist.
Also with all due respect to other members of this forum, some don't even know that with their FTA systems and dishes on C or Ku bands they are dealing with microwave technology.
Keep up the good work and welcome to the FTA hobby.
