Platform Compatibility: Linux Ubuntu and variants,Windows and Mac OS.
Inputs: iambic,paddles, bug via winkeyer interface.
Standard inputs like a keyboard and mouse.
Some basic information for those unfamiliar with Morse keys:
Example of a straight key:
A straight key is the common telegraph key as seen in various movies. It
is a simple bar with a knob on top and a contact underneath. When the
bar is depressed against spring tension, it forms a circuit and allows
electricity to flow.
I don't think it is easy to get consistent detection of the input
characters using a straight key because the dashes and dots sent by a
human using this type of key has inconsistent timing of the dots and
dashes. That can easily confuse a computer.
Keys having two separate levers, one for dots and the other for dashes
are called dual or dual-lever paddles. With a dual paddle both contacts
may be closed simultaneously, enabling the "iambic" functions of an
electronic keyer that is designed to support them. The operator can
create a series of alternating dots and dashes .-.-.-.-.-.-.-.-.-.-.
A single-paddle also utilizes separate contacts for dots and dashes.
A example of a dual lever paddle:
More on morse keys:
A typical Winkeyer interface:
It uses a FTDI driver, it is also supported in Linux. It uses the
winkeyer server. It is an UDP server allowing operation of the Winkey
USB by K1EL with any Linux program with UDP keyer capability. It works
in the same way as the popular cwdaemon.
But, there is a thing.. NO ONE HAS USED THIS METHOD TO LEARN TO RECEIVE
AND SEND! It should work for both!
There are NO software that can teach both, only receive!
How the software should work:
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
signs. It then waits for a four characters input using the keyboard or
the morse device, 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.
It may also be possible to display the character K and send the
character in morse 5 times or shorter and wait for 4 around second wait
for the answer using the morse key.
It should also be possible to adjust the mininum and maximum number of
characters in the groups and if they are of random size.
It should support Farnsworth timing ,that is that characters are sent
at the same speed as selected, while extra spacing is inserted between
characters and words to slow the transmission down. The advantage of
this is that you get used to recognizing characters at a higher
speed,the characters does not "blend together" as easily and thus it
will be easier to increase the speed later on.
Available during Realistic mode:
signal fading and white noise to imitate more "realistic conditions", as
Hannes Matuschek Kochmorse has it. It is available at:
Kochmorse does have a CW detector, but it can't be used to input
characters during learning how to receive Morse and it seems not to
support winkeyer interfaces.
Morse alphabets that should be used : Primarly International, but the
possibility to add regional extras like the Norwegian Ĉ Ĝ and Ċ. Those
extras should be possible to add to the characters learned with a option
