About

MTP Callsign Trainer

Features
Read full description

MTP Callsign Trainer is built for operators who want to read callsigns quickly and accurately. It focuses on the patterns you actually hear on the air: prefixes, suffixes, portable indicators, and regional formats. Choose your difficulty level and session length, then copy live-style callsigns at speed. The feedback is straightforward so you can spot common errors and adjust pacing without getting lost in extra features. Callsign copying is a unique skill because the format changes by region and by operating style. This trainer emphasizes variety so you can recognize common structures without hesitation. It is ideal for contest preparation, sked practice, or everyday CW readiness. Sessions are short enough to fit into a break, yet structured enough to build confidence over time. You can use the trainer as a daily warmup or as a focused block when you notice certain prefixes or suffixes slowing you down. The goal is steady recognition and a relaxed copy flow, not just speed for its own sake. That makes it useful for both new operators and experienced contesters who want consistent accuracy. Because it is a dedicated micro-app, there are no distractions from other modules. Just start a session, copy what you hear, and build confidence one call at a time. MTP Callsign Trainer is part of the Morse Trainer Pro ecosystem, giving you a consistent training feel while concentrating on a single skill.

Longpath teaches you to hear Morse code, not to decode it letter by letter. And it lets you practise on the Morse key you already own, and with other learners, live. FREE TO LEARN Longpath and all of its training are free: copy and send training, Learn characters, your own Morse key over Bluetooth, the statistics, and private practice on the channels. On iPhone and iPad, Longpath shows a small banner and, now and then during training, a full-screen ad. The ads are non-personalized, and the app does not track you. Remove Ads, a one-time purchase under Settings, Ads, takes them away for good. The Mac app shows no ads. CHANNELS: LIVE MORSE WITH OTHER LEARNERS Morse is meant to be shared. Channels gives you ten numbered channels where learners send to each other, live. The waterfall shows where people have been keying in the last ten minutes and how many are on each channel; tap one to join. Inside a channel the Morse reads like a chat: every sender's characters appear in bubbles, with their nickname above, and you hear everyone with their real timing and their real mistakes. Send with your own Morse key or the on-screen key. Not ready yet? Private practice is always there: nobody hears you, and it works offline. CHANNEL SUBSCRIPTION The channel subscription is only for joining the live channels with other learners. Your first seven days there are free, then it is monthly or yearly. Training never needs it, nor do private practice and the waterfall. Channels, Channel subscription shows your free days left and opens it at any time, with prices and Restore purchases. YOUR OWN MORSE KEY Every telegraphist has a favourite key. With the BLE key interface you plug it straight into Longpath: a straight key, a single paddle or an iambic paddle, connected over Bluetooth to your phone, tablet or Mac. The app produces the sidetone, decodes what you send and shows exactly where your timing drifts, so you train on the very key you will use on the air. The interface is open hardware: build it yourself from the public ble-key project, or order a parts kit or an assembled key straight from the app. Bluetooth key support is free. COPY TRAINING BY EAR Copy training follows the Koch method. You start with two characters at full speed and add the next one only when you are ready. Because every character is sent at full speed from the first minute, you learn its rhythm as a sound, never as a row of dots and dashes you have to count. Farnsworth spacing keeps the gaps between characters wide while each character stays fast: thinking time without the wrong rhythm. CHOOSE YOUR CHARACTERS Learn characters shows every character with its rhythm and a toggle. You decide which ones are in play, and copy and send training draw from that one set. SENDING No key at hand? Practise on the on-screen key, straight or iambic, with the same sidetone and the same decoder. YOUR PRACTICE, IN VIEW A practice stopwatch, a daily goal and a statistics view show what you actually practised rather than what you meant to practise. LOCAL AND PRIVATE Training runs on your device. No account, no sign-up, and copy and send training work without a network connection; only the channels go online. Your progress belongs to you, and on Apple devices it follows you to your other devices through your own iCloud. Longpath counts anonymous usage statistics so we can see which parts of the app are used. It asks you once whether they may also carry a random install ID; saying no keeps them anonymous, and you can change it any time under Settings, Usage statistics. SUPPORT LONGPATH If Longpath helps you learn Morse, you can say thanks with a donation under Settings, Support Longpath. A donation unlocks nothing; it simply supports the development. Longpath is named after the long way round: the path a Morse signal takes around the globe, and the path you take to learn it.
