HamMorse: Morse code practice on the iPhone

Ham Morse allows you to practice morse code on your iPhone or iPod Touch. It is designed particularly for Ham radio operators and others who wish to achieve or maintain a high level of proficiency in this classic mode of communication.
You can practice morse code created from the following:
  • Letters
  • Numbers
  • Callsigns
  • Punctuation/Prosigns
  • All (Alphanumeric and punctuation/prosigns)
  • Top 100 and Top 500 most common words
  • RSS Feeds


The code is sent using the Farnsworth timing, at speeds at or below 15 words per minute (wpm) the characters are sent at 15wpm with extra space added to slow the overall speed down to the target speed. Above 15 wpm the actual code timing is used. Currently the application goes from 5wpm to 25wpm with an audio frequency of 750Hz used for the code. Note that an update has been submitted to the App store that will allow the application to go up to 50wpm This should be available shortly.
You can practice a variety of sets of characters from individual random letters all the way to the current news stories from around the world. The available letters can be customized on the settings page and provide groupings similar to those used in the Koch and Candler methods.
There is a callsign setting to allow you to practice receiving random amateur radio callsigns, a mixture of letters and numbers (eg AA9PW, G1SNT) that often prove troublesome when learning the code. A punctuation setting provides punctuation and standard morse code prosigns. The top 100 and 500 most common words are included, this is a great way to start to recognize whole words the key to really improving your speed. Finally a selection of RSS news feeds from around the world are included to provide the opportunity to copy real sentences and keep up with the news at the same time. Note that the RSS feeds will only work with an active network connection.

Additional features:

  • You can pause and restart the code if you interrupted.
  • If the phone rings while you are practicing, the code pauses so you can take the call
  • You can show or hide the text as it is being sent.
  • Its styled much like current amateur radios – black plastic case with an orange backlit screen

My Favorite Morse Code Trainer On Ubuntu

I would like to share my favorite Morse code trainer software on my Ubuntu operating system.

First is Xcwcp

Qt frontend to unixcw
Xcwcp is an X-based interactive Morse code tutor program.
It lets you choose from a number of options for practice, including sending
random characters, random words, and characters from the keyboard. It will
also receive Morse code that you send using the keyboard or mouse as a Morse
keyer, and display the characters it sees.

Second is Aldo

Aldo is a morse code learning tool which provides four type
of training methods: blocks, koch, file, callsign.
Blocks: Identify blocks of random characters played in morse code.
Koch: Two morse characters will be played at full speed (20wpm)
until you'll be able to identify at least 90 percent of them.
After that, one more character will be added, and so on.
File: Identify played characters generated from a file.
Callsign: Identify random callsigns played in morse code.

For me, 2 apps is enough. One for X and one more for command line interface. The important is how to listen and sending the code. I still on my process to learn Morse code.

Configuring TinyTrak3Plus On Ubuntu

TinyTrak3Plus is an APRS GPS position encoder which, when connected to a serial GPS and a radio, will transmit its location at an adjustable rate. TinyTrak3Plus is the fourth generation in TinyTrak series, and is available as a kit construction project, or as a built and tested unit, providing an inexpensive way to build a mobile tracker without the need for a full TNC. It is configured by connecting to a computer's serial port, and running a simple configuration tool which allows setting of all user options. After that, the computer can be disconnected, and a GPS connected in its place for operation.

TinyTrak3Plus has the following features:

  1. Decodes any NMEA-0183 compatible serial GPS sending $GPRMC or $GPGGA sentences. USB only GPSs will not work.
  2. Can provide 5V power to an external GPS (such as the Byonics GPS1 or GPS2).
  3. Transmits position, altitude, speed, heading, and timestamp (hour/minute/seconds or day/hour/minute).
  4. Supports SmartBeaconing, which adjusts transmission rates to speed and turning.
  5. Can transmit position in MIC-E, NMEA, or APRS ASCII text format.
  6. Two configurations, with all user options switchable.
  7. Burst after voice / Send Position Now input.
  8. Handles position resolution down to 7 inches.

TinyTrak3Config running on Ubuntu using Wine.
