It's a lot of fun to take an idea from concept to a working unit but anyone
who thinks they're going to build something better than what's available
should learn how to engineer by going to school or get a job around a lot
real smart designers.


But so many so called engineer designed radios were inspired mostly
by accountants, who hate the parts in radios because they cost money
to put there.
Engineers had pitched battles with accountants in company staff offices all the
time.

So it isn't too hard to build an AM radio with at least 10 kHz BW and low thd,
but it usually uses a couple more tubes the engineers of yesterday were
forbidden to use.
A superhet isn't rocket science, its schoolboy electronics, and any determined
person could build such a radio if they had the will, the tools, workshop, etc.
Sure, the old junk from hamfests does help the ability to experiment more
easily,
since things like IFTs can be tweaked and tried, and who cares if you
stuff one up?
