## What is MTP Code Groups?

MTP Code Groups delivers CW / Morse Code focused practice with random character groups, similar to classic LCWO-style drills. This training mode is perfect for smoothing out hesitation and improving character transitions. Pick the group length and session size, then copy each group at speed. The feedback is straightforward so you can spot weak areas and refine timing without getting lost in extra features.

Code group practice is a staple for operators who want cleaner, more automatic decoding. It removes context clues and forces pure recognition, which makes real-world copying feel easier by comparison. You can use this app as a daily warmup, a speed-building sprint, or a way to sharpen precision before longer QSOs. Sessions stay compact, which makes it easy to repeat them and track improvement.

Adjust the group length to match your goals: shorter groups for precision, longer groups for flow. The idea is to keep your rhythm steady and your spacing consistent, which carries directly into on-air copying. Over time, the random groups help reduce guesswork and encourage confident recognition of each character.

MTP Code Groups is a dedicated micro-app with a single, targeted focus. It is part of the Morse Trainer Pro ecosystem, offering a familiar interface while keeping your attention on a single training routine.
