The application is somewhat picky about the listening conditions, so if it doesn't work, try adjusting the volume or repositioning the phone in relation to the speaker.
If you can't get it to work, send me an email with a link to a recording of the transmission and I will see if I can improve the application.
Any other feedback welcome.
A waterfall shows the frequency spectrum of 100Hz to 2500Hz. Just slide the waterfall slide on a RTTY carrier frequency and DroidRTTY will decode the signal.
In transmitting mode characters can be entered trough the keyboard. 9 Macros are also available to store standard texts like “name and qth” and “station info”
DroidRTTY also now includes a logbook. Callsign, Name RST etc can be easily tranfered into the lookbook from the receiving screen.
The logbook also includes ADIF export and import to transfer your logbook data to a PC based logging software.
Version 1.10 also includes 50 baud / 450Hz shift to receive the German Weather Service (Deutscher Wetterdienst)
If you are a ham radio (amateur radio) operator or just want to learn morse code.
With a lot of settings it is very comfortable to adjust Morse Trainer to your current level.
The following settings are available:
- Frequency (200 - 2200Hz)
- Waveform (sine / triangle)
- Fading (to reduce click at the end of a dot or dash)
- Speed (2Wpm - 52Wpm)
- Farnsworth speed
- Spacing (spacing between dots or dashes)
- Dot-Dash Ratio (length ratio of dashes compared to dots)
- Letter Spacing (Space between letters)
- Word Spacing (Space between words)
Five different learning modes are available in Morse Trainer
- Random groups of X mode: Morse Trainer will play groups of X randomly selected letter, numbers or special characters. X can be an amount between 1-9. Those characters can be individually selected. If you want to learn just "s","i" and "e" just select the 3 letters and Morse Trainer will create groups of X with those 3 letters.
The characters can also be chosen from 20 lessons of the Koch method.
- Real ham radio callsign mode: Morse Trainer will randomly play real amateur radio callsign from a database of 5000 callsigns which appeared in Contests over the last couple of years.
- QSO text mode: Morse Trainer will play randomly play QSO text. The database consists of 300 different qso texts.
- Most common English words mode: Morse Trainer will play randomly the 500 most used English words.
- Own text mode: Enter your own text and Morse Trainer will play it over and over again.
- Ebook mode: Text files can be loaded from SD card
Morse Trainer is priced less than the cost of a fancy coffee and it is a great app to learn and improve you CW speed away from your amateur radio station or your PC.

This app is intended for patented ham radio operators and should be used in conjunction with a tranceiver using its microphone (audio in) port.
The default message format is:
BCN DE # @ &
# in your call sign (add /B to be recognized as a beacon)
@ is your WWL locator grid
& is a custom message
BCN DE IU4APC/B JN64DD QSL IU4APC AT YAHOO.COM
To use the app all you have to do is:
1) Set the message (red chars). You can use prosigns for it. # for call, @ for locator and & for a custom message. The line with the orange chars shows the message that will be sent.
2) Set the call, locator and a custom message. The locator can be automatically calculated by pressing the GPS Button.
3) Set the WPM speed.
4) Set a custom frame size (the number of minutes between Each message send) or leave the automatically calculate suggested minimum value.
5) Set the audio Frequency.
6) Press START To immediately start sending the CW message
7) Press the REPORTS Button to open the reversebeacon.net page with REPORTS showing where your message has been heard.
The STEREO checkbox enables the sending of dits and dahs on different audio channels. This can be used to drive external hardware to emulate a real paddle.

*** Now includes band limits for All Amateur Licenses ***
*** Calculators for Yagi, Dipole, J-pole, and Vertical antennas ***
*** Callsign Lookup is now included!!! ***
Callsign database is pulled from FCC website and updated daily! Callsign lookup works for U.S. callsigns ONLY.
Results include address, current and previous license updates, date of any updates, type and class of license, and even includes a link to the FCC database for even more details. Address can be mapped on Google Maps by tapping on the address.
The contact log allows you to store information about a completed contact including date, time started, time ended, frequency, mode, station, location, signal reports, and an area for general comments about the contact. A must for field day and general book keeping. Data and start time are filled in when starting the log to save time. End time can even be filled in automatically upon saving the log entry.
The contact log also comes with a handy search feature for quickly locating that one of a kind long distance contact you like to brag about. The search is focused on fields chosen by the user. If you want to search for a specific call sign select station as the search location and enter the call sign in the search box. Search keywords are CASE SENSITIVE meaning capital or lowercase letter DO matter.
A summary of the band limits for each class are included. Always refer to the official ARRL Band Plan when in doubt.
Some simple formulas and calculators are included for quick reference in the field and includes: Yagi, Dipole, J-Pole, Vertical antennas, and wavelength calculator.
- Learning : discover the morse code characters for each number or letter of the alphabet
- Answer a quiz : listen to the audio signal and select the corresponding morse character out of the choices from a list
You can also enter the text you want to translate and send the equivalent Morse signal immediatly.
In case of emergency a SOS signal is pre-recorded and can be transmitted instantly in various formats (audio, flash, screenlight, vibrations)
Morse Decoder can be used by Ham Radio (Amateur Radio) operators or anyone else interested in decoding Morse code from a Radio or any other device.
Morse Decoder includes a "waterfall" to show a frequency spectrum of about 50Hz to 2300Hz. A narrow band DSP filter can be set for the frequency of the Morse code tones by tapping the waterfall. The DSP filter is followed by an automatic gain control (AGC) to compensate for changing signal strengths.
The detected signal will be shown as a graph and several algorithms will then detect the speed of the Morse code and convert them into readable text. Speeds of less than 4 Wpm (Words per Minute) to more than 50 Wpm can be decoded.

This is the first version of Morse Decoder.
It has been tested on several Android devices and it performed very well or even better than PC based decoding software. However, since we are not able to test the performance on all 150+ Android devices there is the possibility that Morse Decoder will not work on all devices. If Morse Decoder doesn’t work on your device you can uninstall Morse Decoder within 15 Minutes for a full refund (This is the time frame given by Google and I am not able to change it). If the 15 minutes passed and you are not happy with Morse Decoder email me as soon as possible at email@example.com. Please include your name and the model of your phone in the email. I will then refund you the money as fast as possible. It is important that you include the model of your device. I will try to find the cause for the malfunction or include your phone model in a list of “not working” devices.
