MTP Code Groups
Read full descriptionHide full description
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.

Learn Morse code the way high-speed operators actually hear it: as sounds, not dots and dashes. MorseCAT is an Instant Character Recognition (ICR) trainer. Every character is sent at real speed from day one โ you never count elements, you learn the sound. Then you answer the way an operator would: key it back. LEARNING IS FREE. FOREVER. โข The full guided path โ every letter, number, and prosign, in the proven CW Academy order โข Listen & Learn โ hear each character introduced as pure sound โข Listen & Say โ say the character out loud and MorseCAT grades you by ear โข Free Practice โ your speed, your character set, whenever โข Word Patterns and weekly LICW class groups โ drill exactly what your class covers โข Progress that means something: a per-character mastery heatmap, recognition-time tracking, a copy-ceiling benchmark, streaks, and a proficiency rank ANSWER LIKE AN OPERATOR Hear a character, key it back. Use the on-screen straight key, the touch paddle, or plug in real hardware โ Bluetooth MIDI keyers and paddles (TinyMIDI, HaliKey, VBand-style interfaces) take over automatically the moment they connect. Motor memory in, guesswork out. REAL SPEED, HONEST NUMBERS Characters always sound at your character speed (default 32 wpm, floor 25) โ fast enough that there's no time to count elements, which is the whole point. Difficulty comes from closing the gaps, Farnsworth-style, never from slowing the code down. MorseCAT measures your time-to-recognize on every single character, so you always know which ones are instant and which ones still make you think.

Verdict
The clearest difference is in-app purchases: MTP Code Groups at none against MorseCAT's 1. MorseCAT's advantage is update cadence (every 2 weeks vs every 6 weeks). On price, ads, device support and iOS requirement there is nothing between them.
