Rigs Pinout

I stumbled upon this great site with pinout for most rigs. PTT pinout for Kenwood, Alinco, Icom and many more. Those interested for their rigs for APRS or other purpose can go to this site. I will also have a link in the sidebar.



Sample of pinout and descriptions.

Practicing Morse

Go to this site and build the circuit, program it, hook it up to your keyer and start sending CW.

Or download the schematics and PCB from here.

CW Lessons

k7qo.iso.zip file is 350,578,272 bytes. Read the PDF file first before anything else. (Note this is a newer version, i have not download it yet. may not be simila to what i have). To me this is a good way to learn morse. There are other software that teach you morse. Remember when you were a kid and started to speak. By hearing your parents you picked up the language. This method is same. Important thing is not to count the dit and dah. Once you are proficient you will be hearing word instead of letters. Just like reading this post. You are not reading the individual letters but the whole word.

Best of luck.

MORSE

Hopefully by now you have made your iambic keyer. Now to learn morse code (CW). But you need to first build a circuit to practice your morse on. You can download the diagram from here or go the the author/creator's site for more info. Later i will be posting morse lessons for download.

9W2GU's homebrew simple IAMBIC key

My simple Iambic key build for practicing Morse. It works fine, but the feel is not of that of commercial product. But it work and it is a simple project to do. Materials I use to make mine is wood, PCB and lead for weight.








The Base
Using a piece of wood for base 5" x 5" x 0.75".














Then, poor me, with out a CNC, i painstakingly chiseled out a hole at the bottom 3" x 2.5" X 0.5" deep. This will be used to fill with molten lead, so that to give extra weight to the base and not move when keying.












The paddle mounting

Two small wooden blocks. Oner for mounting the paddle and the other for contact.

Smaller block is 1.5" x 1" x 1.5"
Lager one is 1.5" x 1.5" x 1.5"










The smaller block and contact plates. Hole drilled through all for ground contact.












The Lead

You will need lots of these. I get mine from car's dead lead acid battery. Then washed.















A tin container is used to melt the lead. You'll need about half full of molten lead. Once the lead melts, there will be more sand like and other stuff floating on the molten lead. This you need to get rid of after you pour the molten lead.











The molten lead poured into the bottom side of the base. Let it cool naturally. Do not pour water to cool. Takes about 20 minutes.

The Paddle

Made from PCB and painted. Hole in the center is for ground contact. Those on the side for mounting on the holder.












The IAMBIC keyer

Connect screws with bolts on both side of the paddle for ground contact. Adjust distance and tighten. The left side is dit and right is dah.












Side view of the wiring. Notice the blue wire. That connect the conatct point to the ground.

















Red is dit and white is dah.














The completed IAMBIC keyer.










I use the IK0WRB module for this iambic key for morse tones.

PCB foil, TopSilk in PDF format and HEX file




Now to think of a better design. Any better ideas out there?
