Those of us who got into Amateur Radio in our youth -- if we learned more on 
our own -- might sometimes have more understanding of electronics than some who 
walked off a stage with a BSEE.

Learning how to read at age three, I latched onto my parent's library after we 
returned from the UK in 1953, and was quickly reading adult level books.

I got into Amateur Radio after a teacher showed how insulated wire on a nail 
could pick up thumbtacks and paperclips, so I  I bought some wound inductors 
from our landlord's junkyard, and found one shaped like a doughnut.   When  
powered for a short time, that TV  focus coil could propel ball bearings across 
my bedroom enough to stick in the wallboard.   Dad of course talked to the 
landlord, and a crystal-radio kit distracted me.... with Dad promising a 
transmitter if I built the ARRL's two-6AQ5 regenerative receiver.

I got one of the WV6 Novice licenses and with a short hiatus, got my General 
Class at 14 or 15, with Advanced and Extra after I joined the Army Signal Corp 
at 17, reenlisting for  Avionics maintenance, and on retiring, walked into 
engineering positions with no degree or coursework.

From a Quora Answer:

If we’ve worked hand-in-hand with engineers of other specialties, we will be 
more able to produce — working with them — solutions or designs that allow both 
to maximize the desired results. We will be likely to to see fixes (when 
needed) that a conventional education might not consider.

And if we’re both accommodating of overall goals; resourceful, thoughtful and 
flexible, creativity that suggests factors others don’t think of may be 
acceptable despite others’ failure to see what we may suggest.

That’s how an autistic engineer (even sans coursework or degree) can work, and 
how I had a 21 year career in communications and avionics in the Army — but it 
was 28 years after that before I learned I was “on the autism spectrum”. I’ve 
worked in EMC test and/or design engineering in a number of fields; TEMPEST and 
consumer/business computers, Digital Telecomm Network equipment, portable 
defibrillators, and Aviation EMC.

The physics are the same; only the standards are different

And these days, you get an EE Degree, and they barely cover BJTs, everything is 
FETs/MOSFETs. BJTs are basically considered “old, obsolescent tech” -- 73 de
