Title: Electronics instruction
Post by: N1BIL on October 22, 2012, 05:02:21 PM
I'm trying to upgrade to an [4 examples and explanations of the circuits and how they work and work with other circuits.
Thanks,
Bill (KJ6VSG)

Bill,
Your 4 examples, did you try to post them or do you need 4 examples.  What types of circuits? There are many here to answer, but we need more specifics.

Bill:  You're breaking up.  Please repeat all after "upgrade to an." 

With your electronics background, I can't even guess what you're asking.  Please try again.

back end of any Heathkit manual, the "how it works" section.

descriptions/circuits section of any RCA receiving tube manual.

just about any old Popular Electronics article has a "how it works" section as well.

believe the old GE Transistor Manuals from the early 60s also show example circuits and how the actives in the circuit work.

or are you looking for something like old DeVry or RCA Institutes home study manuals, which are often on ePay?  I learned a ton from a neighbor's old DeVry course books in the mid 60s.

See xkcd for one example ...

or there's Electronic Circuit Collection at:

DiscoverCircuits.Com has 30,000+ electronic circuits, cross-referenced into 500+ categories.    We have searched the web to help you find quick design ideas. We make every effort to link to material posted by the designer.

Enough?

Some of you guys must be windtalkers - I am still trying to figure out the question.

Great information resources posted - for young and old.

That is not what I wanted to type. I don't know what happened.
I'm looking for information concerning a electronics course which will help me pass my Extra exam.

 :D  Bill, I used to talk like that before I quit drinking!  LOL. 

Seriously, I don't know of an electronics course available that will help you with the Extra test.  Since the question pool is available perhaps you can find well written simple books to explain the principles of electronics needed to understand the questions on the test.

But as I said, with your electronics background I can't understand this.

You might find this useful: http://www.hamtests.co.uk/
You got to log in though.
I'd just take the questions from the pool and whatever seems to be a problem will be answered here for sure.

Get the book and any questions or concepts you don't understand, then post a question about it here. I am sure there are a lot of hams on here that can help you figure it out.  Good luck on the Extra.

My wife would say I'm more of a windbreaker.  ;)

I did not learn enough, when getting my engineering degree, to pass the Extra class exam.  I doubt there will be a specific "electronics course" that would provide what you need.  Much of what's on the Extra exam is practical, and legal.

However, there is one book that does contain every single bit of theory you'll need - the ARRL Handbook.

I'd get that, then get Gordon West's Extra Class study guide.  Go through the qustions in the Extra Class study guide, and the ones for which you are not prepared, look up the relevant topis in the ARRL book's index.  Recent version of the Handbook come with a CD with all contents searchable.
