Good Morning! I'd just like to say this is a Wonderful program and I'm really enjoying improving my code skills here. I'd like to make a request to improve this Great Program. Please use random generation of characters when we use this test to hone our skills. The program sends the same text repeatedly and after a while you mostly memorize it, instead of learning the letters and numbers. This would make this program so much better as a teaching/learning tool for us serious to improve our skills here. Thanks So Much for this Program..I hope to be using this for years to come. Might even be a high speed cw op eventually! Best 73! NM5X

Thanks for your nice comments.
I wonder if this is a caching problem or something like that. Here, I seem to get different texts every time I start a lesson. Is anyone else having problems like this? I'm glad to investigate, but currently don't really know where to look for hints. Seems to be random texts here...

The problem I'm experiencing is that what is sent and what is recorded does not agree (Lesson 1). If it sends three m's and two k's, it shows three k's and two m's.. It's hard to improve your skill when it show opposite of what it's doing. Is anyone else having this problem, or am I'm the only one stuck on lesson 1?

I tried lesson1 no problem. At low speed however I had difficulties to distinguish groups. You might want to record the sound to check the behaviour.

how to deal with this system, when the signs are reversed?, such as period (.), and comma (,) are generated are not correct!
Posted: 2010-08-31 09:32
interestingly, in Russian Morse code, comma and period seem to have different definitions. In English (and German, etc.) period is .-.-.- and comma is --..--, while for Russian, it seems to be common to use ...... for period and .-.-.- for comma. Correct?
This has been discussed and explained before, but then I didn't think about it anymore: http://lcwo.net/?p=forum&t=262
It would be possible to change the meaning of the characters depending on the language which the user choses here on LCWO.

I think this site should teach "International" Morse code. Please don't confuse things by offering different things for different languages.

Since the end of July I have run the full set of 40 lessons, currently 872 practise lessons.
I have had a new random characters set each time, so it might indeed be a caching problem at your end. My training sessions have been on several different computers, all running windows (several versions) and IE8.
Fabian, I do think however that in random character selection the numbers are chosen more frequently than the characters. But this could also be a personal perception from me.

g8tmv: I agree; but customized characters should/could be introduced as optional features at some point in the future. This would also include other alphabets such as Cyrillic (which the CW generator used on this site already can handle).
PA1FOX: I am using PHP's mt_rand(), so it should be pretty well randomized...
Regarding the original posting: Note that it's two years old. Back then there was indeed a reproducible problem that caused the browser to use an old cached version of e.g. the callsign trainer, and send the same calls again in the next attempt. This was fixed long ago, by sending proper expire- and cache-control headers.

It could be that your server is running out of entropy. You might want to think about using a driver like "randomsound" assuming it's a Linux type box or even installing one of these:

Sorry, you're right. I did not notice the old posting.

It is a fantastic website here where a Moron (Nomen est Omen, tnx AH8DX fer the Nomen, due to accepting it as User-ID the offense is limited to a singular event) and Idiot like me feels vy familiar.
The russians try to interchange the male(,) and female(.) gender. Guys 90+ retired from US railroad try to push American Morse.
19000 registered subscribers already, 99 % is advanced to Koch lesson 1, 15/5, 70% correct.
and Our latest Thai Guy Chris emphasises "perseverance" he is already due to his willpower arrived at day 5 without a recorded exercise on this web site.
Look at the people here around and conclude that you are crazy because your behavior is too much sigma's separated from the average.
The MP3 and characters of an exercise are generated simultaneously as a compound source code of your exercising web page, so entropy or atropine sounds good, as an eye opener, but
yes but... complete this sentence as an exercise in rudimental reasoning.
