Hi David,
Well at least the surplus military gear commonly adapted and used by hams
was build to decent performance specs.
Re your "The FCC needs to catch up with noise floor challenges & modern
technology."
Be careful what you wish for here because if the FCC were to address these
challenges and mandate rules for minimum Tx performance specs then most
solid-state rigs and amplifiers would be proscribed due to their lousy /
mediocre IMD performance :-(
It's probably best to leave the sacrosanct ham bands as a free-for-all
anything goes as long as you keep your spectral muck confined within the
designated ham bands... :-)

I don't get where the notion comes from that commercialization vs home
brewing is something new to Ham radio.
For at least 75 years commercial & military surplus gear have been a common
part of our hobby.
Many Hams have interests other than building - they are not lesser Hams.
The FCC needs to catch up with noise floor challenges & modern technology.
IMHO, YMMV ...
