Receiving Morse by Sound

01Sound Foundations10 lessons

The first eleven letters, until you recognize each one without thinking.

  1. 01Recognize K and MGuest
    More details

    Your first two letters, chosen because they sound nothing alike. K is long-short-long, M is two long tones. Learning them as whole sounds (not as dots and dashes you picture in your head) will be the entire method from here on out.

  2. 02Add UGuest
    More details

    Two short tones and a long one. The drills now mix K, M, and U, so you have to know each sound without relying on a fixed order.

  3. 03Add RGuest
    More details

    Short, long, short. R is K with the tones flipped: swap K's long-short-long for short-long-short and you get R. Worth hearing that link now, before speed makes them easy to mix up.

  4. 04Add EAccount

  5. 05Add SAccount
    More details

    Three short tones in a row. The goal is to hear the group as one shape instead of counting to three, since counting falls apart the moment the speed picks up.

  7. 07Add APremium

  8. 08Add PPremium

  9. 09Add TPremium
    More details

    A single long tone, the exact opposite of E. Those two are the shortest signals in Morse, and much of the alphabet is combinations built around that one contrast.

The remaining fifteen letters, until you can receive A to Z.

  3. 13Add IPremium

    Mastery XP
    150 available
  4. 14Add JPremium
    More details

    Short, long, long, long. It's W with one more long tone on the end, so the only thing to catch is whether you heard three long tones or two.

  7. 17Add VPremium

  11. 21Add HPremium
    More details

    Four short tones. This finishes the short-tone run: E, I, S, and H are just one, two, three, and four taps. Since the only difference between them is the count, the goal is to hear H's length as one shape instead of counting to four, which is where it slips into S.

  12. 22Add BPremium
