Actually the pictures do help!!  I already had those but missed the writing on the one that identifies the wires 'CW', 'CCW' and 'W' - those give me what I need. I'll add information to my manual and get back to work.  Thanks.

Subject: [4SQRP] Bayou Jumper -Soup'er Up'er Question

 

I am helping another ham by installing a Soup'er Up'er (SU) in his Bayou Jumper (first generation, white face panel). Up to the point where I am wiring up the Soup'er Up'er board to the Jumper - specifically on page 10 of the SU manual ( about 2/3's of the way down the page)  where you make wiring connections to the new Fine Tuning pot (FTP) - the instructions say:
   *  Solder the wire from CW to the J7 pin 1
   *  Solder the  wire from W to the J7 pin 3
   *  Solder the wire from CCW to the J7 pin 5

I understand that CW et al is a reference a pin on the FTP and to direction of rotation of the FTP (eg. W means the Wiper pin of the FTP) and that the other two refer to the other two pins on the FTP but which one?  I ohm'ed the connections on the FTP and they are color coded and I can tell which end pin is shorted to the wiper when the FTP is set full CW and full CCW but which is which?

I can (and will if need be) just guess at it and then change it if the FT goes the wrong direction. But thought it might be worthwhile to ask first!! Hope this makes sense.

If anyone is interested, I have both books - Introduction to Radio Frequency Design (complete with 3.5 inch floppy disk) and Experimental Methods in RF Design (original 2003 edition, with CD-ROM).  The EMRFD book has some water damage on the last 1/4 of the book but only slight and still quite usable.  I can mail both books media mail for a total of $35 if anyone is interested.  Email me off list with interest.

Re: Cricket 40 No Receive Audio

Yes, I checked with several different headphones as well as using a small powered speaker system.  Another HAM, N4MJ, gave me a list of things to check.    I just need to sit down and walk through that as well as verifying that every part was in fact installed in the correct location.   Knowing my luck, I probably have something else out of place.   Great suggestion as it’s usually the simple things.

Michael,

Welcome to the wonderful world of CW, I am not too far ahead of you CW wise but it truly is fun learning.

On your Cricket.  Have you checked your headphones for correct plug and to be sure they work ?

Re: Recommendations for electronics books

There's a lot of good books on electronics, many of which focus on RF circuits, but here's the list from my own library:

  • The Art of Electronics, by Paul Horowitz. This one is very pricy, but very complete. I have both the paper and ebook versions.  https://www.amazon.com/Art-Electronics-Paul-Horowitz-ebook/dp/B01BYJO2JU/ 
  • Practical Electronics for Inventors (various editions) by Paul Scherz. I like this very much. Very readable, but also complete. I have both the Third and Fourth editions. https://www.amazon.com/gp/product/B01D5LXUYI/
  • Electronics: A Top-Down Approach to Computer-Aided Circuit Design by Allan R. Hambley. This was a hardcover I purchased because it had more of the engineering of designing circuits with computerized tools. Might not be precisely what your looking for, but inexpensive enough to be worth a look anyway. It has some good sections on circuit simulators, like PSpice. https://www.amazon.com/gp/product/0023493356/
  • Complete Electronics Self-Teaching Guide with Projects, by Earl Boysen. This is a decent hands-on book for basic electronic information. Like with most works, there's a heavy emphasis on the formulae that underpin electronics, like Kirchhoff's Circuit Laws. A decent book with some useful projects to help cement the info in your mind. https://www.amazon.com/gp/product/B008K9AH6A/ 
  • Electronics from the Ground Up: Learn by Hacking, Designing, and Inventing by Ronald Quan. This is one of those books where the paperback edition is cheaper than the Kindle edition. I'm not entirely sure why. I got this one because of the dreadful pun in the title, but it's actually a fairly good book. The author is an RF engineer, so there may be more of what you're looking for in this, but the learning curve does steepen as you go further into it.  https://www.amazon.com/gp/product/B00O2A7H9G/ 
This is by no means an exhaustive list of books that you might want to look at. It's some of the ones I have in my personal library, notably the most basic and fundamental texts on the theory of electronics. How-to guides are fine for what they are, but you at some time need to learn WHY these things do what they do, and the math is an unavoidable part of the why. Why does a circuit have two resistors, with a line going off from where they connect to one another? Because it's a voltage divider. Learn the formula, and why you'd use one. How do you know how the value of an unknown resistor or capacitor that the markings have rubbed off of? Kirchhoff's Laws can help you figure it out. I'm not extremely far into these books myself, as I have limited "spoons" for wading through them, and a memory so bad it might better be termed a forgettery, but some of these books are considered classics in the field regardless of my opinion.

You might find one or more of them at a local library if you want to look at them first.

Any of the handbooks, articles or pamphlets written (and illustrated)
by Paul Harden NA5N, are also gold.

Solid State Design, while long in the tooth, really gives you enough
theory to begin to design your own circuits.
