Morse Code Sound Machine

Wanted to create something that will introduce Morse Code to kids. It had to be simple and looking like a game, so I ended up with making Morse code Sound Machine.

Idea is that kids enter their names and then listen how it sounds in Morse Code and also Amateur Radio.

There is animation of sending Morse code and options to change speed and tone frequency. I guess that is enough to keep them interested for a while.

Application is written in plain JavaScript and can be run in any web browser.

Morse Code Sound Machine source code is available at GitHub. […]

Ham On Key

That day I was turning dial through the band
My radio was squeaking sounds like a sand.
I could hear some local rag chewing hams
And they talked that bands are open nice.

Oh call
CQ CQ CQ some more time.
Get my answer and I’ll finally be fine.
You, make me, make me, make me wanna cry
And now I beg to hear you call just one more time.

So I say,
Wait for me,
wait for me,
wait for me
Oh, oh, oh.
I never worked no one from your DX zone before.
I say,
beam for me,
beam for me,
beam for me
ay, ay, ay
And if you hear me, happiness will make me high. […]

Wouldn’t it be awesome to have Morse Code playing instead of plain ringtone on your phone? You would know who calls without need to reach phone. Of course it would require you to have skill of recognizing Morse Code, but that is minor issue, right? If you do not know it yet, it can be learned. It’s great skill to have, anyways.

Well, there is simple tool that may help: Morse Code Generator . It creates audio file with sound of Morse Code using your custom text. Generated sound is nice sinusoidal tone, pleasant for ears.

What you do is type in text phrase, choose Morse Code speed and Tone frequency and click button Generate. […]

Building dipole antennas is always some kind of improvisation. Center insulator is quite simple and may be made in short time with jigsaw and drill.

As I jumped in CNC world I need some simple tasks to learn how to use FreeCAD and other software. So, dipole center piece is ideal just for that. I’ve finished project and learned a lot in the process.

Finished projects is uploaded to Thingverse: https://www.thingiverse.com/thing:4149187

You may use CNC mill or 3D printer to make this part. Pay attention to use material strong enough to survive possible strong forces.

Beginning of October (1st to 16th) is time of the year when amateur radio operators from Užice participate in celebration of Užice City Day by activating Užice Award .

Užice is old city. It’s first mention in written document is in document found in Ragusan archives, dated October 9th, 1329, almost 700 years ago.  However, city is much older, it was on map of Roman Empire, and archeology found evidence of settlements as early as Neolithic age.

As award manager I have to give good example by participating in award activation. For me that means going portable as I cannot practice ham radio at my home. […]
