OpenShack CW
Learn it. Master it. Measure it.
A CW path for the first character, the next clean QSO and the pressure of a serious pileup. Train receiving and sending as two halves of the same operating skill.

From first sound to serious operating.
Beginners and experienced operators should not be forced through the same front door. OpenShack CW keeps each goal clear while letting the tools grow with the operator.
Learn the code
Hear characters at proper speed, add them gradually and bring real sending into the process early.
Learning path →Train the operator
Work on words, callsigns, pileups, clean timing, conversation and speed under pressure.
Mastering tools →Measure your progress
Chase a personal best in RufzXP, PileUp, CW Summit, RX tests and TX analysis.
Training and competition FAQ →Start without buying the suite.
The Web Morse Trainer is the first free OpenShack CW entry point. It gives newcomers a useful place to begin immediately, while the full Windows suite adds deeper training, keying analysis, competitions, chat and operating tools.
Additional selected tools can join the free layer over time without making the full suite less valuable.

Train what happens on the air.
Recognition, rhythm, pressure and clean keying matter more than memorizing diagrams of dots and dashes.

RufzXP and RufzXP TX!
The classic CW trainer, now both ways: copy callsigns with your keyboard or send them with your paddle.

PileUp
Pick calls out of competing signals and stay accurate under contest-style pressure.

TX analysis
See what you actually key, character by character, and improve timing instead of guessing.

CW Summit
Climb through increasing WPM with personal-best lines, ghost runs and accuracy visible.

Morse Chat
Train CW by chatting with other operators or an AI practice partner.

Decode and inspect
Use audio and TX decoders as another view of signals and your own keying quality.
Keep the real key in your hand.
The Box lets OpenShack CW hear your paddle during training. For remote operation, keep it beside you for local sidetone, paddle input and footswitch PTT. Use it with Flex Keyer, OpenShack Remote or a second Box at the radio.
