Hi folks,

about two years ago I coded a little Morse Decoder which uses the mouse as the input device in JavaScript, e.g. to be used in a browser.
Getting the mouse click events with a millisecond resolution works surprisingly well with the Firefox browser. What I didn't manage to get running well back then was a decent sidetone.

A few weeks ago I played with the code again and found that Firefox's audio capabilities have dramatically improved in the meantime, and it's indeed possible to generate a sidetone without too much delay by very simple means. It's still a bit clicky because I switch it on and off without any rise- or fall-times, but at least it's not delayed much (on a halfway modern/fast computer).

The result can be seen here (as mentioned, it will probably only work with Firefox and Chrome at this moment, possibly also with Opera):
http://lcwo.net/transmit

I have some ideas how to improve the sound, and also I am planning to implement a little Morse Chatroom with it on LCWO.net eventually.

Hi Fabian,

The idea is wonderful, as a matter of fact for me this was the only feature I found missing in CWOL, (I just love CWOL).
As for now I used MRX morse code to get the PC to decode my CW sending.

I just gave it a try (using Firefox here), and found it quite difficult to send CW using the mouse button.
But after a while it is working.
I'll see if I can recuperate an old mouse and solder my CW key to the left button in parallel.

I'll keep you posted.

Many thanks for your outstanding efforts.

Germain

PS:I do not mind the "bad" CW sound, on HF receiver it is far worse ;-)


Posted: 2013-01-28 10:09
Works nicely here (Firefox 18.0.1, XP). Clicks are no worse than some stations in the CQWW 160m last week end..

Display of character spacing could be helpful for beginners (in the status line where it displays eff. speed etc.)

Gruss

Gerd.

thanks Fabian
the feature is great (works well on Firefox 18.01 on Win 7 Pro 64) and really useful !!
can I also thank you for the main programme, it has really got me progressing through the code in a way that no other software has - the "Morse Machine" is especially effective !!

the slash character seems to bring up an asterisk. Other than that, I'm very pleased to see this added to LCWO... a very welcome addition to an already much appreciated site. Regards, John G7JMZ.

..... I'll see if I can recuperate an old mouse and solder my CW key to the left button in parallel....


I thought that this was such a great idea that I added two 4mm sockets to an old USB mouse for my son so that he could plug in his Czech morse key. Dunno how much use he will get out of it, but I had a blast and it's works really well !

Thanks for the great idea Germain, & thanks for the javascript Fabian!

Just added the / character. When I put the script together I just quickly added the characters that came to my mind, but "/" was somehow not among them...

Great to hear that it works well with a Morse key attached to an old USB mouse. Have to try it myself when I find the time for that.

Hi there Fabian, Thanks for adding the slash character. Don't worry, I'm sure that no one will mention the comma, lol.

Best Regards,

Fabian;

Thanks for the site in general!!! The TX practice seems to work just fine for me! I'm using Mac OS and Safari. Took some getting used to - but I'm pretty sure it was me and not the software. :o)

Just getting my license, and this was just what I needed to get my CW component.

Thanks again!!

Fabian;

FYI: I wired my CW key into a USB mouse, and now I can use the key instead of a mouse to practice! Very cool!

One addition to the site that I would fine helpful would be the ability to hear a tone when you press the "key" key. I think it would help with remembering if I could hear it as I send it.

Otherwise- awesome!

Hi Tom,

tomc938:

great!

In Firefox the sound should have worked already.

With Safari in principle it should work too, but as far as I remember it only supports MP3 files (not OGG/Vorbis) with the HTML5 audio element.

I just added an alternative MP3 source to the audio element, the browser should automatically pick the right one now.

Wonderful idea, Fabian! Is there any way to connect an iambic paddle to the internal keyer on my Icom Pro 3?

73, Chuck, K6ZIZ, in rural Northern California


Posted: 2013-02-19 16:44
k6ziz... wire the output of your keyer,what you normally plug into your TRX "Key" jack,
into an old mousecable.
(you may have to kill a mouse for it.)

(left mouse button cables = shortcut = beep)

Fabian, despite his great talents. Cannot "code" hardware for you :-)



Posted: 2013-02-19 16:49
fabian, consider someone is actually using a mouse for this - the "key" field is really tiny and when you key.. the mousearrow easily moves out ofthe key-field.

how about to make the entire window a "key" field
with exeption of the QRS/QRK/CLEAR buttons? Same effort - but eliminates the need to 'aim' while keying.....
------------------
additonally/alternatively... it might be a good
idea to allow for keyboard-based-keying (space key)
eliminates need for "aiming" and should improve accuracy as space-key keying is much easier than mousebutton-keying ...imho.

gruss, timo


Posted: 2013-02-19 19:48
Thanks, Timo - guess I'll use a J-38 and keep it simple. Chuck K6ZIZ


Posted: 2013-02-20 02:31
There is an easy way to wire in a key (I don`t know about how a paddle works), but you do have to sacrifice a mouse to do it. I tried simply using a USB cord, and shorting every possible pair of wires, but was not able to get it to recognize a click. (or anything else for that matter) There is a lot more in a mouse than just the circuit being completed it appears. So I broke apart a mouse($1CAD at second hand store) and removed the board inside. I found the micro-switch for the left mouse button. I soldered one wire to each side of the switch, and then went to a 1/4 inch female plug. Then I just plug in the key, use the mouse on my computer to move the cursor over the `key` button, and pound away. The cursor never moves (unless you bump your mouse) because the only thing being activated is the left button key.

It`s a great way to improve accuracy!

Tom


Posted: 2013-02-20 02:40
Oh, and I forgot to mention - the sound is working under Firefox and Vista, and somewhat in OSX (10.6) and Safari. It clips the sound on the first character somewhat, but is usable. Since I have a PC to use, I`m not pushing for a possibly complicated fix for a small number of users. (I can`t believe I just said that!


I`ll try it in Linux and let you know how it goes in the next couple of days.

Tom

Hi, Fab idea. Really loving this and your whole site. I can't prase you enough.

I can't seem to get it to work on IE8, XP just gives page error, works lovely with chrome so i'm a happy chappy.
Administrator


Posted: 2013-03-09 17:41
Yep, the TX training won't work in IE8. As far as I know, HTML5 support (and therefore the ability to play the side tone) came with IE9+, but I have not tested it.

Fabian


Posted: 2013-03-20 06:46
hello Fabian,
idea of TX sending with mouse is great!
I tested with Firefox Mozilla 14.0.1 & chromium 18.0.1025.168 under ubuntu:
in general TX with mouse works, but it sounds incorrectly: dots and dahs are not splitted with silence: just a continuous sound without pauses. but chars are determined correctly and this is funny.

thanks for lcwo.net and 73!
Dmitry


Posted: 2013-03-26 08:49
TKS to You, Fabian! It's a nice function - TX-training.
1. All works good: Win7, Chrome ver. 25.0.1364.172 m
2. Is it possible to use a keyboard key as a CW Key? Is it good idea? Or may be You already tried this case and decided to use mouse button?
3. TKS to germain - Germain for good idea to connect a CW key in parallel to computer mouse's button.


Posted: 2013-03-26 19:11
Sir ! I tried that TX-training and it is not good to me. Maybe two different knobs to write dih and dah
is better ? But nice where and when it works !
Administrator


Posted: 2013-03-27 10:07
ur5rks: I did some experiments with the Space bar to send CW, but the timing in the browser doesn't seem to be precise enough for keyboard events

OH1FQZ: That's something to consider, but I am not sure if e. g. the right mouse button can be used for this purpose like the left mouse button (i. e. if it generates a similar event in the Browser)... I will have a look at it, thanks for your input.

Posted: 2013-04-03 05:12
works great! I love it.


Posted: 2013-04-06 03:51
hey great site. the cw tx practice works good. it's about the only practice i can find for sending morse code since i don't have a real key yet. good to practice with until i get a real transceiver. very helpful site, good work! 73 - kg4aos


Posted: 2013-04-14 17:33
Hi Fabian. You did a really great work. I thought I'd never learn CW because seems to be too tedious, but Im already knowing all the characters! Im a rookie in ham radio and I don't have radio stuffs, (neither an old mouse wired to a bencher). In the TX Trainer Im using the mouse button to click the Key button, but is not confortable. To improve a little this I think it could be nice to has a keyboard button as an alternative to click the Key icon with the mouse button (maybe the space bar). Maybe it not the best solution but a good improvement without welding cables o mouses. Many thanks


Posted: 2013-05-06 21:15
Camino on OSX works! I notice that it is not identical to the receive trainer, as the "=" is translated as a "*". Is this a different dialect or a bug or is it sloppy sending? (using a Junker straight key connected to a mouse here)

What would be nice is to record the key up and down times as timestamp, so you can play the code back in a chat session as if it was sent live. By multiplying time you can even go slower/faster.

I would also like to see some statistics which should be helpful in improving sending. Maybe the recognized character overlayed with the sent times:

Detected an A: --- ---------
Your timing: - --------

Keep up the good work!


Posted: 2013-05-21 10:04
hello Fabian, i am 75 y old and passt my cw 50 y ago(PA3AHA)12 wpm.
I have searched the whole web to find this transmit thing. Nice , very nice.Because of my laptop without a serial input and windows 8 a cannot use other transmit training programs.
On ours it is excelent. OK the mouseclick is not a wonderfull thing to learn transmitting morse
The idea of tom c938 is a very good one. I shall buy one of those cheap mouses
windows 8 pro, Firefox, laser wireless mouse
thanks and continue
guy van der velden


Posted: 2013-06-07 19:21
I really like the Tx Training. It is the one thing that I felt was missing from lcwo.net. I hope you get your chat working sometime.


Posted: 2013-07-28 20:12
Good job! Like the stats!
Is easier to key on a notebook - - sorta like using a flat mouse.
Can't see word and sentence separation. Guess my fist needs work.


Posted: 2013-07-28 20:54
RE: stats
What does "ratio" mean?
Can guess at "eff. speed". :>)
Does program work best when "speed" = "eff. speed"?
Administrator


Posted: 2013-07-29 19:01
"ratio" in this case is the dot-dash length ratio, which ideally should be 1 : 3. But with some browsers, the click events seem to have a poor resolution, leading to strange calculated values.

Yes, ideally your speed should equal the effective speed, that would be perfectly spaced code. Normally the effective speed will be a little lower though, since people tend to make spaces a little longer than they "should" be.

Apologies too Fabian for not saying "what a great idea" the sending is. I am sure with a bit of tweaking you will have the ultimate Morse training system!

Posted: 2013-08-27 19:25
Hi Fabian,

thank you for running and continuously working on this site. The TX training is great, as well. I use a key wired via an old USB mouse. This requires to keep the mouse pointer over the button "Key", and after some time of coding my real mouse moves away. So it would help to make the button somewhat bigger.

Cheers, Kurt


Posted: 2013-09-08 06:39
I'd like to see a program that graphs out transmission sending timing such as the army's old RD-60 machine as seen in this youtube video:http://www.youtube.com/watch?v=59a-yLIJLyQ (6:25) and have it displayed in this navy's training film on youtube: http://www.youtube.com/watch?v=iC5RQNSSZH0 (2:39).

My difficulty for sending is not knowing how well I'm doing with my timing and spacing.

For listening I'd like to have the ability to select the time interval of each dit so as to give me time to mark it down until I have the entire message written out in dits and daws. I first need to discern between dits and daws before I can hear letters.


Posted: 2013-10-11 19:56
Re: creating a "keyer" mode:
There are two ways to capture a right-click event in JS. The easy way would be to use the oncontextmenu event, though I'm not sure if that picks up the "up" event very well. The other is to check the value of the button in the function (your "down()" and "up()" functions).

More detail can be found here:
http://stackoverflow.com/questions/4235426/how-can-i-capture-the-right-click-event-in-javascript

Hope that helps.

Love the keyer, though it's horrid trying to use with a laptop touchpad....

Hi, Great tool for a little practice between lessons. Thank you,
Can you add the equal sign =
It only works when I click the "key" button. It is easy to move off the button and then nothing happens. Can you make the key button larger or a large one elsewhere on the page?


Posted: 2014-01-17 02:27
Great bit of work. I initially glued a knob onto a second mouse, and blacked it's eye so it couldn't move the cursor. Parked my first mouse cursor over the "key" button and away I went. cannot fault the system, however the mouse is a bit sloppy. Pulled the mouse apart and used a jumper lead to tap out some cw and it is great Will solder a couple of terminals/or a connector in for my key which should arrive next week. Thank you very much for LCWO, it is great. You can die with a smile on your face having served mankind so well.

Hello,

great tool.

Please can you check: I miss the letter "=".

Thanks a lot
Volkmar (DC8VS)


Posted: 2014-02-02 19:08
"=" -...- is the new character in lesson 16, Volkmar. All lessons above lesson 15 have it, but I believe it is nowhere in the word training word lists (whereas "-" -....- is contained, like "Sachsen-Anhalt").

Hi Fabian,
Great cw tx learning tool you've made. It works great on my MacBook pro OSX 10.9.1 with Firefox and Chrome but it doesn't work with Safari. But for me that's not an issue.
I use a morse key but I guess it will work with an iambic keyer with an SSR outlet as well. But I haven't tried this yet.
74 - Ralph


Posted: 2014-04-30 15:43
hi fabian !
Test results for writing morse code with mouse :
-slow speeds under 8 WPM working well
- mobile net connection can cut out part of the letter .
hopefully cw-chat is coming soon.

Posted: 2014-05-02 18:23
ie 11 works windows 7
nice idea, maybe arduino set up as hid unit would work for iambic key, would defo work as normal mouse key will look into it, if i can get it working ill post code on here


Posted: 2014-05-07 08:33
tried the cw trainer on android phone, (Samsung Galaxy) buttons are to small, and the screen keeps zooming on touch, maybe a mobile screen? this would be brilliant.
Also on the main page as well buttons are too small for mobile users. Brilliant website though, have recommended a few fellow re-enactors to use it to learn morse.


Posted: 2014-06-06 01:59
add a iambic paddle
ie: number 1 and 2


Posted: 2014-06-25 00:04
Thanks for the site. I have tried on various occasions to learn CW and failed miserably. Knowing how difficult developing software can be I truly appreciate the work and effort you have put in.
I'm only just starting to learn but what I have seen/tried so far is great. Thank you.


Posted: 2014-09-13 23:02
Thanks for providing this site, as a early learner [less than a week] using your TX sim is a great brake from listening to the incessant beeping, I would just like to echo others comments saying the button is small, and looking forward to the possibilities of an online cw chat system. [once I can copy more than 4 letters]


Posted: 2014-12-16 09:47
Greetings from South Africa :-) First a "thank you" for excellent service - APPRECIATED! Experimenting with using an old PS2 mouse with connection to straight key for sending using Opera and regret that delay is problematic. I will try Firefox browser (and Chrome) later and report back as idea of being able to practice sending with 'intelligent' feedback is a very good idea! Till the next time remember to KEEP SMILING :-) 73 Nigel ZS6RN


Posted: 2014-12-17 17:14
Hello again :-) Further testing using Chrome browser is MUCH better! Have not tried Firefox. Wondering if development will include 'keyer' (using left and right mouse buttons)? Thanks again for hosting the site and providing learning aid for those of us wishing to become proficient in using CW. Recently I came across a new CW Yahoo group that could be of interest to users of LCWO: cwragchewers-subscribe@yahoogroups.com Till the next time remember to KEEP SMILING! 73 Nigel ZS6RN


Posted: 2015-01-11 17:28
Hello Fabian,
I'm working on my handmade straight key that I want to connect on an old mouse to use your TX training...in the meantime could you add "spacebar" as key? I generally use a notebook and the bar is more realistic instead capacitive pad.
tnx


Posted: 2015-01-11 18:49
Thanks for a great site, Fabian. One of my sons just donated an old, mostly-dead mouse. I'll try to sire my Czech key into it. Bonus: I get to practice my soldering skils too!

alexsgv: I remember there were some pitfalls when using the space bar, but I don't recall exactly what they were... I will look into it when I have checked some other things from the todo list.

In the meantime, maybe this would do:
http://www.bennadel.com/blog/2267-decoding-morse-code-with-javascript.htm

It is actually using the space bar and on a first glimpse it appears to work well.

What about interfacing to the cwcom protocol? Recently I have discovered that there are open source implementations, i.e. https://github.com/8cH9azbsFifZ/irmc

A way to interface a key or paddle would be great.


Posted: 2015-02-22 02:12
Hi,

would it be possible to add a letter prompt and scoring? Pick a few (or a lot) of symbols and the page prompts a random one. You then tap the CW and the page evaluates. Similar to Morse Code Trainer on Android. I really like that app but the tapping on the screen doesn't work real well.

thanks!

Hello Fabian,

thanks for improving this great website step for step. I like to suggest something. Would it be possible, to use a USB/Comport adaptor to connect a real morse key.

A 9-pin comport has 4 handshake inputs and 2 handshake outputs. The outputs RTS and DTR can be used as a self containing power source. If activated, they provide a positive voltage between ~6...12Volt and some mA. The inputs CTS and DCD, for example, could be used, to read the status of a key or a paddle. Nevertheless, for me it would be already perfect, to connect a straight morse key.

The USB framerate is as high as 1 kHz, so the longest delaytime can be expected in a 2ms range. If i remember right, this is a lot faster, than any keyboard or mousebutton can deliver it's data.

Regards,
Bernd

Hello Fabian,

I was skimming through the comments and I thought instead of hooking a key through a usb port, why not plug it in to the mic port? I don't know how hard it would be to program but it would be easy to hook up.

Hello Fabian
a great touch to the program, it would be unique to be able to chat in morse in a chat room, great idea were waiting when you have the time. Just soldered wires to the micro switch in an old mouse, put my key on, it worked a treat.73 for now


Posted: 2015-08-03 19:22
I normally use a USB trackball. So I found and old Microsoft PS/2 serial mouse, six pins in a green jack. After rebooting, Windows 8.1 picked it up and used it in parallel with the trackball. So far so good! The left button microswitch had 5.0 volts across it, perfect for connecting to my touch keyer (cwtouchkeyer.com, Model P1BS). I cleaned the filthy insides of the mouse, drilled a hole in the case, and soldered a cable across the microswitch. I was lucky. It barely fit. The keyer worked perfectly. Two problems: I measured the latency. It's a huge 80 milliseconds, which is not surprising with later versions of Windows. Musical keyboards are practically unusable. So I have to use the side tone coming from the keyer, and mute the sound coming from the computer. Another problem with an easy fix: I have to set the expected speed to about half the real speed coming from the keyer. Otherwise most characters are not recognised. For example, keyer at 15 WPM and expected speed at 8 WPM works fine. After I install Windows 10, I'll measure the latency again.


Posted: 2015-08-14 02:44
It was a struggle getting Windows 10 to work. I had fix the flashing desktop bug by using msconfig to disable Windows Error Reporting Service. Then I measured the latency again. It's much worse. Windows 8.1 was 80 milliseconds. Windows 10 is about 180 milliseconds.


Posted: 2015-09-03 14:23
I tried again measuring the latency on Windows 10 using an easier, more accurate method. It is not nearly as bad as I reported above. I now think it is about 55 milliseconds on my old computer. That's actually usable.


Posted: 2015-10-05 08:49
Hi Fabian,

Would it be possible for you to add in a function whereby a character (or string of characters, sentences, common QSO phrases etc) are generated, that the user must then correctly send?

The users transmission would then be checked against the original phrase.

Thanks

Jake


Posted: 2015-10-16 19:04
Works good on Linux kernel 3.18.11-gentoo, but would it be possible to add possibility to use button by pressing keyboard, let's say, space keyboard button? I would make html "Key" button focused by pressing Tab / pushing down with mouse and moving mouse out of the button while holding left mouse button, and then just use space to send Morse.


Posted: 2015-12-05 11:17
Hi
I have a problem with "=" in "TX training".
The result is always "*". I don't know if it is problem with me or the software.

Posted: 2016-01-25 17:28
Mobile internet connections are problematic to this service because nature of those are that sometimes there is very short connection pauses and in the long run results are frustrating mixes of mouse writings of the morse code.
i found out that first time when i listening sdr-radio CW and some letters of the radioham Callsigns were variable because of the reason of those pauses and esp letter U can be heard I or A .


Posted: 2016-04-08 08:11
how about having the option to choose between other buttons other then the mouse.


Posted: 2016-05-21 16:49
Hey there,

I went with the solder-cable-to-left-key-microswitch way and was very impressed with the way it's working. As reported above there is a certain latency involved. You might consider bottling this up into a Java App that gets down loaded to use the local JVM to offset the latency issues. Just at thought. Spectacular work!!
I hope this keeps up as I'm seeing more folks coming back int the CW realm.

Yours,
David, KE0IPR

what I would like is another function of the lesson system, which would output random text, instead of a cw sound file, with the lesson's characters only, that I could use to practice tx.

There is a program out there called cw decoder. It will send and decode cw. If there were some way to incorporate the send side of this program into lcwo, maybe this would make all of this work. Also check out this website:

Reality check; we all recognize the importance of proper sending technique. Using the mouse of my computer to send code via the experimental TX here, I find that it is useful to get the timing down to send cq de call sign what ever.
However, whether we choose to use a straight key, paddles, bug, or iambic paddles... the use of a mouse is more like a straight key. Personally I use paddles and recently acquired a straight key. I would like to have an interface oscillator that I could plug into and use with this site as a practice medium. I like the RX lessons here but we should use our own paddles or keys to send with so that we develop the consistency we need for good TX on the air.

a code practice oscillator is a pretty neat thing.

Thanks for the great program. I'm working my way through the receive side and am hoping to learn to transmit the characters as I learn each new one through receiving. Having an Koch style transmit trainer would be great. Having a visualization like Precision CW Fistcheck would be helpful.

To use the spacebar for keying, paste the following snippet into the browser's address bar, then hit :

javascript:(function()%7Bdocument.onkeydown%3Dfunction(e)%7Bif(e.keyCode%3D%3D%3D32)%7Bdown()%3B%7D%7D%3Bdocument.onkeyup%3Dfunction(e)%7Bif(e.keyCode%3D%3D%3D32)%7Bup()%3B%7D%7D%7D)()

Some browsers will redact the leading "javascript:", so you may need to type it manually after pasting.

A Iambic keyer by using two keys could work fine or two separated touchfields like

dit dit x dah dah
dit dit x dah dah

Great page!

I come from China and not good at English,so please ignore the gram error.
I think it will be batter that add the training of alphabet, words and little article. And if change the mouse action to keyboard(Space key) it is more fun in training.

Great work!

I use left click part of the touch pad.

6 years later...
And still no morse chatroom.
I'm trying to stay positive, but I feel like the owner of lcwo.net left us along time ago for other projects.

This is unfair on Fabian. He's been providing this site for free for years.

With regard to online Morse chat rooms, I'd like to see one, there are some already on IRC but they are always empty.

I don't mind donating money. But I don't think money is the issue here. He's already stated he will never collect money. So his motivations are obviously coming from something much deeper, perhaps a profound love of morse code.

He also stated he was planning on implementing a "little morse chatroom" 6 years ago. I'm just really sad that it hasn't happened yet. And I am trying to express that sadness. I love morse code too and was really excited about this announcement.

Maybe I am being childish. But I don't care anymore. If a few sincere tears help, I don't mind crying in front of such an esteemed group of people as this. Fabian is like a guru or role model to me. I will cry again in 2025 if I haven't met him or you all using morse code by then.

I would appreciate to have a user-defineable keyboard key or joystick button as input.
How about the idea, to use 2 side-by-side keyboard keys to simulate an elbug?

On my PC the detected speed changes very fast.
This gives a large amount of wrong decoding.
It would be helpful to slow down the time constant of speed detection.

In my surely not so humble opinion it would be wise to eliminate this cripple experiment from this website.

It is frustrating because it is fixed speed, not adaptive, complrtrly wrong becsuse hen you sent perfect with the wrong speed you get a lot of errors presented.

and above that learning sending Morse code with a mouse is contra productive.

In general learning to copy is much more important. When you know how correct code sounds, you are in the position to create it because you hear what you create and you know what is wrong in your rhitm.

So when somebody want to exercise sending, use a real Morse key, a cheap one a childs toy will do the job, together with an adaptive decoder. that is a decoder that adjust automatically to your speed, and makes the best guess of your keying.

A better way is to produce an mp3 Morse code of some text at 10 or 12 wpm, normal code, so NOT 20/5 OR 20/10 BUT 10/10 play it repeatedly, and key it synchronous with the sound you hear from the mp3.

Use a beeper and a battery to make your key sounding your cripple QSD. That is the fastest way.

Forget about the cripple feature with non adaptive speed and a mouse on this website.

It is even much better than using an adaptive decoder on your key.

Those two sentences must be interchanged in the posting above+.

I can't edit my posting myself, because I am black listed. SRI

Hi Fabian,
I am making a second attempt to learn Morse thanks to your website. I have an idea and do not know if it is good or not, but you can attach a key to a USB to RS232 converter. One of the wires fron the key to 5V in the USB side, and the other to the CTS pin on the RS232 side, pin nr.8 of the DB9. Then attach the USB to the PC. You would have to make some kind of code to listen to the CTS of com port whatever, and this is the key. This works well as a PTT on the Echolink, and I think it would be useful here aswell.

Hello Fabian,
Just discovered this tx training facility, it's a wonderful idea - just wondering if it is possible to use one of the keyboard keys instead of the mouse, as the mousepad on my laptop is not sensitive enough to tap out accurately no matter what speed I try to do it. I'm having a lot of fun trying, but not getting anywhere!
Thank you so much for everything you have done on this entire website, it's just amazing :)

Hi,

Probably you can use an USB external mouse in your laptop.
Two other things you can do:
1. From an old telephone hook unscrew the carbon microfoon and the telephone hearing element. Place the microphone against the telephone, such that the sound from the telephone enters the microphone. Electrically make a series circuit telephone-microphone==key and a battery.

2. Use some beeper, I got one out of a defect magnetron oven. Put the beeper in series with a battery and a key, and you are all sat.
