Hmmm ... I swear I didn't see the project bench where they build electronic projects for ham radio, make up coax cables, or repair / restore transceivers. I didn't see a soldering iron or breadboard anywhere. I'll watch the video again I'm sure I missed that.
A lot of hams don't do any such thing---they buy ready made up cables, commercially made antennas, &,of course, radios.
On the other hand, you won't see a lot of people on this forum "making up coax cables", either.
It is distressingly common to see posts enthusing about the fully assembled coax leads someone has bought on eBay or whatever, here.
The problem is that, like sporting clubs, the people who get to run the National Amateur Radio Associations are often the same type as those who are in Management elsewhere, & apply the same thinking to their hobby.
If I may say so, they have the same attitude to the "Hobos" that is often exhibited on this Forum, with less justification, as at least those on eevBlog have the messy benches & old solder burns to prove they "mess around with Electronic crud!
As one of the "Hobos", I have dead radios & test equipment "awaiting repair", a huge quantity of horrible crusty old coax connectors & adaptors, plus various other junk.
Interestingly, the older & crustier the coax connectors are, the more likely they are to be good brands.
All the nice new shiny ones are "no-name" from the PRC!
