Hi Larry,

I agree with you completely. I'm an "old iron" too, and my job is to educate
young students in (power)electronics, digital technology, and something
more. Also I'm a trainer for people, which want to get their HAM-licence.
These people are very interesting in electronics and HAM-stuff.
Not so my students.
I have a lot of electronic and measurement equipment in my shack and I know,
how to handle with it.
Most of the young people have only 4 interests:
1. Is there WiFi available?
2. Is the cellphone battery fully charged?
3. Where is the next party?
4. Are there enough girls to "screw them up".

Working in their job, get a good education for their profession and get the
knowledge to repair things instead of put them in the waste... NOTHING!
Cellphone battery is damaged? Exchange the battery? No, throw it away and
ask granny for a amount of bucks to get a new one.
This is our future?! Awful...
Too much money, to less interestings.

I guess, the chinese citizens will "overun" our economics with high speed in
the next future.

Mr. Spock says: "According to my calculations... you are an idiot". This is
our youth...

So, off-topic mode ends here.

Have a great day

Hate to say it guys-
Our generation really rocked in the Electronics department. Ken Burns where
are you??? (Ken is the mastery behind the PBS series, "Empire of the Air",
"Baseball" and "The Civil war")

Remember the days of getting on a plane with a Tektronics 465 scope - you
did not leave it for baggage to handle, as God forbid you land and the scope
is on a trip to the Bahamas.. We did component level repair.. Even on disk
drives. Someone mentioned the CDC drives with "Cake-Box" removable platters.
I had a head alignment pack and the $3,000 repair simulator, you could
completely service that 80 or 300Mb disk drive. with The repair simulator
and it was as big as your Tektronics 465 scope. Then you had 17-18 heads to
align. You tightened them down with a inch-ounce torque wrench. I had one
site with about 25 of those CDC 300Mb drives.. The operator loaded a
platter, it didn't work, so he went down the line loading that bad platter
in perfectly good disk drives faulting At least 5-8 before calling the boss,
as it was a Saturday; he was alone. The boss, immediately stopped him from
loading it in yet another disk drive, They called me in, I grabbed
everything I had.. But I never had a complete set of heads.. There was an
upper, a lower and a servo.. I had about 10-12. I spent 20-30 hours on
site.. Removing heads, polishing them on IBM punch cards with toluene, to
remove the iron oxide, then inspecting them as the heads flew only microns
above the platters. Re installing them, changing absolute filters and I
think I got better than 1/2 of the damaged drives back up, that weekend.
Then ordering parts... Kids today have no idea, about how a disk drive
works. What a low level format is, or bad block lists are. They replace sub
assemblies. Do they even carry a soldering iron, or even a wire wrap tool?.
They don' t carry scopes.

So here's to us old farts.. the guys that knew if a 200 ohm resistor was bad
and you didn;t have one in your resistor box, what resistors you could
connect together to replace that 200 ohm resistor...

I once flew into Syracuse NY, and rented a car -off to the hospital in Old
Forge, NY. hours away.. I was working on a Gamma Camera.. Found a shorted
0.01uf It was taking down a power supply. Who has a 0.01uf cap go bad?
Well, I Found that a ham worked at the hospital and we went with him to his
hamshack and he had a baby food jar full of disk ceramics. We fixed the
gamma camera. Had I had to go back to Syracuse to find an electronic parts
store, It would of downed the equipment for another day plus doubled or
tripled the bill..

Kids today do not have the where with all to be able to provide the customer
satisfaction we did on a daily basis. Today's throw away society.

So I raise my beer to those who worked past midnight, and were back at other
calls by 8am the next morning. And fixed things, didn't replace them.
