No no no no no no no no no, that is exactly not what I meant and want at
all. There should be more "somebodies" who know and understand this, not
one or two who solve problems for the majority of mere mortals.
Processing RF with computers is already a big thing and it's becoming
even bigger. Nobody will understand every aspect of it, but everybody
should at least understand enough to solve or mitigate problems. Amateur
radio is as much about enjoying communication as it is about enriching
your knowledge. The more knowledge there is the easier it becomes to
solve problems. Hope you can appreciate my point of view. Cheers, Hans.
