[Håken Hveem <krbjhvee@xxxxxxxxx>]

Compatibility: Linux Ubuntu and variants.

Inputs:
CW decoder using a soundcards mic input or products like Winkeyer.
That should enable use of a CW tone generator connected to a straight
key,iambic,paddles or bug. Standard inputs like a keyboard and mouse.

Training mode:
First the program sends a series of K's in CW for 30 seconds while the
character K is displayed. Then it repeats the procedure with the
character M.
When that is complete it sends a four characters  group using K and M in
random places without displaying the letters. It then waits for a four
characters input using the keyboard, shows the characters you have
gotten correct in green, the wrong ones in red. That continues until the
user has gotten 90 % correct of a number of groups, then a new letter is
introduced ( for example X ), it is sent for 30 seconds while the
character is displayed. 
Then the lesson continues using the new character until 90% of groups is
correct, a new character or prosign is introduced and the lessons
continues until all characters are learned. 

Sending mode:
A four character group using K and M at random places is displayed,the
program waits until  four characters have been decoded and shows the
characters you have gotten correct in green, wrong ones in red.
That continues until the user has gotten 90 % correct of a number of
groups, then a new letter is introduced and included in the group at random.

There should be not to harsh timing requirements on sending, some normal
slack should be permitted as long as the CW decoder can decode perhaps
60%~70% of the transmitted CW it should be good.

Notes:
The program should keep track of the characters and prosigns learned,
and perhaps prioritize the most common ones first, and when sufficient
numbers of characters and prosigns is known these are used to build
phrases and typical QSOs. It could also be connected to a score board,
so users can compare scores.
It should also support multiple users on the same software instance.
It should also display statistics of a users progress and time used.
The slowest permitted speed should be 15 WPM. It should also be possible
to adjust the mininum and maximum number of characters in the groups and
if they are of random size. Words should also be possible.

I know that it is possible to add QRM,signal fading,pileups and noise to
imitate more "realistic conditions", as done with Kochmorse.
Perhaps even drifting and unstable tones is possible.

Morse alphabets that should be used : Primarly International, but the
possibility to add regional extras like the Norwegian Æ Ø and Å. Those
extras should be possible to add to the characters learned with a option
in settings.
Also, support for wordlists in English or optional local languages.
