Morse Code practice oscillator diagram

mypapit — Sat, 19 Sep 2009 13:11:04 +0000

This is a Morse code practice oscillator has been built by N2UHC

The circuit is a simple oscillator circuit based on a 555 timer IC. There are only a few components needed to construct it.

Parts list:
IC1- 555 timer
R1 – 150k
R2 – 1K
C1 – 10 uF electrolytic
C2 – .01 uF ceramic disc
Speaker
9V battery clip

See the circuit in action (my own video) that I’ve built myself.

CWIRc : Send Morse Code in IRC – tools for Amateur Radio Operator

mypapit — Tue, 27 May 2008 16:28:05 +0000

Eager to practice your CW skills but you have nobody to practice with? In some countries like Malaysia, CW knowledge and proficiency is still required to operated HF portion (except 10 meter) of the Amateur Radio band.

Having said that, I’d like to present CWirc, an XChat irc client plugin which enables you to send and receive morse code through IRC. Developed by a fellow ham F8EJF, CWIrc has a lot of features which really enhance your CW experience on the internet, including the option of hooking up a real CW keyer using serial port interface.

CWIrc enables you to exchange morse code with fellow irc users on the internet, provided that the other users also knows morse code and has installed CWIrc. Though this might sound a little bit of a stretch when thinking the odds of meeting people with both requirements, it is actually not so in reality. You can find those kind of people exactly in #cwirc on irc.freenode.net server who are eager to chat with you in CW.

Requirements

Linux (or Unix based) machines (I personally used Ubuntu)
XChat IRC Client
CWIRc plugin

Both XChat and CWIrc are included in Ubuntu (as well as Debian) software repository, so you don’t need to compile or download separate package from their respective websites.

Homebrew a creative Morse Key for CW Operation

Watch this video for ideas to homebrew Morse Keyer for CW operation.

For starters… It does not actually sounds like that, I had to lower the voltage because the speaker output is too loud and you can hear that i’m not a good at sending morse too.

Still in progress, I’m still looking to modify it abit and put it in a nice box and attach it with a decent key.

At last my Morse Practice Circuit Completed – sort of

As promised in the previous post,Simple Morse Practice Oscillator Circuit has been completed. Sorry, I cant do anything much with the photo quality as it was taken using my stupid mobile phone.

I promise to include a Youtube video demonstrating its sound and operation. Next, I need to get a decent casing and some cheap morse keyer to go with this oscillator. I might be planning to make one that could interface with CWirc too.

Simple Morse Practice Oscillator Circuit

mypapit — Thu, 13 Mar 2008 06:22:53 +0000

This will be my next homebrew project, a morse practice oscillator circuit. 9W2AZV and I are going to build this as we are preparing ourselves to perfect our Morse code sending/receiving skills.

In the spirit of amateur radio/ham, we will homewbrew the equipment using easily obtainable parts from our nearest electronic stores.

Here’s the circuit

We are still thinking of the easiest and cheapest way to homebrew the keyer, but we are considering to use discarded/faulty computer mouse as our first keyer.

As a bonus, we thought of hooking this keyer straight to PC serial port, so we could use it with XChat CWirc plugin to enable us to test our Morse skill on the irc.

With the amount of work i’m having this week, I would estimate that this project would be completed by the end of March. So stay tune for photos!
