LKMT is designed to train and verify your capabilities in keying and puting chars. For that
reason, it provides a direct compare of required signal and your input on an
To key in morse code, you might use morse key via com to usb converter, mouse or line in of sound card.
A microphone might do as well.
This won't work without some options for listening, so listen training is
included as well and it shows some nice features other tools do not provide.
However, to initially learn morse code, there are probably more convenient
tools at the market - working directly in browser like LCWO, light wight
executables as F6DQM's CW-Morse Code Teacherr and the lots of smart phone
based apps allowing you any training wherever you are.
Instructions - easy: Here we go to -
LKMT: CW - Morse Code Reading Trainer
Let us first see what advantages
LKMT shows as a Reading
- All Settings as
tone frequency, volume
character speed, Farnsworth setting
and the selected characters to train
can be changed during the ongoing
training session with immediate effect - No stop is required
(I personally like vary the speed during a session)
- All settings are visible at a glance.
You are not tortured by menus and sub menus and sub-sub menus:
- Morse code, individually selectable letter for letter or just as a
whole block like "AddAlpha"
- Do you have difficulties with specific signs or a specific mix of some
(Meaning e.g. if there is just one, only this one is provided, if there
are three different, and one character is four times more represented
than the others, it will be provided 4 time more).
There is the option
to influence the probability
of a sign(s) If you enter for example 5
'e', 5 'h' and one 'v',
you will trained with e and h, the 'v' is just the salt in the generated
It, of course, can be changed during a ongoing session as well.
- Farnsworth training method is supported and the effective
speed is shown
- 3 different read training
modes (some in addition for keying):
Groups of five characters
Groups of arbitrary variable length and a some
Any text that you randomly find on your hard drive (I personally prefer
a selection of Chuck Norris jokes)
- All settings are stored
... and used when you start LKMT next time again
- Accurate morse timings,
verified by Audacity:
- Some technical advantages:
- No installation is required - It does not pollute your PC and
- It runs on different OS and Hardware, basically everywhere, where
JAVA is available
Downloads and Prerequisites
Download it here:
It requires JAVA, ideally in version 8 (It has been tested systematically with 7 and occasionally with 6).
You start it best per double click (If your environment provides this
option) or by using the java-command at command line like
java -jar Lkmt.jar
With little requirements to the system, but without sound input interface:
U need Java
to run it ? It is
provided by Oracle for free, available to a lot of different Operating Systems.
Just select the java version fitting into your OS:

Before finishing, I would like to thank Ludwig, DK5KE, and Michael, DF2OK,
for the helpful ideas.
