The new way to practice Morse code.

New Firmware Version 3.x also allows the use of a straight key for all modes!

And you can transceive not just over LoRa, but also over WiFi (and hence across the Internet)!

There is also a firmware version (called „Morselino“), created and maintained by Mathias Jordan, that supports a straight key also for Echo Trainer:

    • Iambic A, B and Ultimatic mode
    • Iambic B parameters (timing) configurable, independently for dots  and dashes
    • Pitch control
    • Output volume control
    • Optional ACS (Automatic Character Spacing)
  • CW Trainer (Code generator)
    • Speed variable with encoder (5-50 wpm)
    • Generates random character groups, call signs, common CW abbreviations incl. Q-Groups, common English words
    • Select which characters to be output (Koch method, or combination of alpha, numerals, interpunction, pro signs)
    • Define length of words to be output
    • Increase inter-character space (like Farnsworth method)
    • Increase inter-word space
    • Optional: output each word twice
    • Can also play text files in Morse Code, these can be uploaded through WiFi
      • Files can contain ASCII text and pro-signs
      • Words in files can also be played randomly
  • CW Echo Trainer (Challenge / Response)

    • Decode Morse code received by a shortwave receiver
  • CW Transceiver
    • Using LoRa (Long Range WiFi)  in the 432 MHz ISM Band!
    • Great for learning how to conduct QSOs in CW
    • Ideal for group learning or learning with a teacher / mentor
    • You can also use Morserino-32 for iCW (CW over Internet using the Mumble protocol) - you need to connect to a PC for that
    • New transceiver mode WiFi Trx allows Morse communication across the Internet (directly over IP, no PC needed)
  • Firmware can be updated over WiFi
    • See video below
    • Update through USB now also possible
