Summary of Contents for Morserino M32

  • Page 1 Morserino-32 User Manual A multi-functional Morse Code Device, perfect for Learning and Training...

  • Page 2: Connectors And Controls

    Connectors and Controls Connector / Usage Control 3.5mm Phone Connect this to your transmitter or transceiver if you would like to key Jack (2 poles): to them with this device. Audio input for the CW decoder; connect the audio output of a receiver 3.5mm Phone for decoding CW signals.
  • Page 3 DC connection to ground through 50 - 300 Ohms.) Connect / disconnect the LiPo battery from the device. For frequent use of the Morserino-32 you can leave the battery connected. If you will not Power Switch use the device for several days, disconnect the battery as otherwise it will be slowly discharged.
  • Page 4 Use a normal 5V USB Charger to power the device and charge its LiPo Battery. The microcontroller firmware can also be reprogrammed through USB (although you can update the Morserino-32 firmware also through a WiFi connection). Through a small hole you can reach the Programming Button of the PRG Button Heltec module (normally not needed).
  • Page 5 - although this is rather minimal in its deep sleep status, a full battery will be empty after a couple of days. Therrefore, if you intend not to use the Morserino for a longer period of time, disconnect the battery from the device using the slider switch at the back...)
  • Page 6 To upload a text file for the Morse code player To update the firmware of the Morserino-32 to the latest and greatest version. This is similar to the file upload, but instead you point it to the compiled binary file containing the firmware (you can get the firmware through the Morserino-32 github repository).

  • Page 7: The Status Line

    On the very right hand end of the status line there will be an indicator (showing concentric half-circles) symbolizing radio transmission whenever the LoRA modus is active (if the Morserino-32 is in LoRa Transceiver mode, or you have set a parameter to transmit LoRa while in one of the CW generator modi).
  • Page 8 English words and call signs). File Player: Plays the content of file in Morse code, that has been uploaded to the Morserino-32. Currently it can hold just one file, as soon as you upload a new one, the old one weill be overwritten.
  • Page 9 The sub-menus are the same as for the CW Generator: Random, CW Abbrevs, English Words, Call Signs, Mixed and File Player. Again, like with the CW Generator, you can set a huge range of parameters to fine tune the generation of things.
  • Page 10 Trx: In this (still somewhat experimental) modus a transceiver connected to the Morserino-32 is being keyed, or you can use the line-out audio to either key for example an FM transceiver, or use CW over the Internet (iCW - this uses Mumble as an audio exchange protocol).
  • Page 11 Morserino-32 starts as an access point, providing its own network (with SSID "morserino"). You need to connect your computer to that network (no password is required) and point a browser to m32.local. A simple form will appear that allows you to enter the SSID and the password for you WiFi network.
  • Page 12 waves is displayed on the right end of the status line. A single click with the encoder button toggles the mode of the encoder between setting the keyer speed and setting the audio volume. Keyer speed is in words per minute (the reference word is the word PARIS, which also means that 1 wpm equals 5 characters per minute.
  • Page 13 In order to prevent counting dits and dahs, or thinking of and reconstructing what you heard, the speed should be sufficiently high (min. 18 wpm), pauses between characters and words should not be lengthened enormously (and it is always better to just lengthen the pauses between words, and keep the inter- character spaces to more or less the normal space).

  • Page 15 (as a blank space, as it were), the whole data packet assembled so far is being transmitted and in due course being played back at the indicated speed by the receiving Morserino-32. When morse code is packed into a LoRa data packet, dots, dashes and pasues are encoded; it is not so that the clear text would be sent as ASCII cgaracters.
  • Page 16 Did you double click from the Start Menu, you will be presented the complete range of parameters. List of All Morserino-32 Parameters Bold values are standard or recommended ones. When called from the Start Menu, all parameters will be availabe for change.

  • Page 18 Char / Word by word Trainer Select, how the trainer should display what it generates Disp Each In the CW Trainer modus, each "word" (characters between Off / On Word 2x spaces) will be output twice, as a help to learn to copy by ear. Here you decide, how often a word is repeated when the response is either too late or erroneous, before a new word is Echo...
  • Page 19 Note: Iambic Modes: When you press both paddles of a iambic keyer, dahs and dits will be generated alternatively, while both paddles are being pressed, starting with the one you have hit first. The difference between modes A and B is the behavior when both paddles are released when the current element is being generated: in Mode A the keyer stops after the current element, in Mode B the keyer will add another element opposite to the one during which you released the paddles.
  • Page 20 space which has the length of three dits. To make it easier to copy code that is being sent at high speeds, and as a good method to learn Morse code, this space can be extended. The code should be sent at rather high speeds ( >...

  • Page 23 (you will not need a password to connect). Once you are connected, enter "m32.local" into your browser on your computer. You will se a little form with just 2 fields: SSID and password. Enter the name of your local WiFi network, and the correspondig password, and click on the "Submit"...
  • Page 24 First you will see a Login screen. Use "m32" as User ID and "upload" as password. On the next screen in your browser you will find a file selection dialog - select the file you want to upload (its name or extension doesn't matter) and click the button labelled "Begin".
