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 firstname.lastname@example.org. 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.
with Ham Radio Tools you can:
-look up callsign information!
-find current GPS location information
-save each contact to a log database stored on the phone
-review and edit each log entry
-search for keywords in different fields of the log entry
-calculate a simple quarter and half wave antenna length
-calculate the wavelength of a frequency
*** 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.
The features in the receiving modes include:
- Spectrum analyzer for easy tuning
- Auto synchronization ( auto slant correction)
- Auto mode detect
- VIS encoding (detects SSTV header and sets mode automatically)
- Level bar for adjusting the audio signal
- Auto save received pictures to SD Card.
- Share received pictures (Email , Dropbox etc.)
The features in the transmitting modes include:
- Pre-load up to 9 pictures from the SD Card into DroidSSTV’s gallery
- Adjust contrast, brightness and saturation
- Template editor for easily overlaying templates over images
- Macro’s for use with templates
EchoLink for Android provides access to the EchoLink network from your Android device. You can use this app to connect to the EchoLink system from almost anywhere, using either a WiFi or cellular (3G/4G) connection.
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.
- 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)
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)
DroidPSK is able to decode a BPSK31 or BPSK63 signal though the build in microphone. Just hold your Android phone or tablet close to the speaker of you Amateur Radio transceiver, adjust the waterfall slider to the PSK carrier frequencies and DroidPSK will start decoding.
In transmitting mode characters can be entered trough the keyboard. 20 Macros are also available to store standard texts like "name and qth" and "station info"
Starting V2.0 DroidPSK now also includes a logbook. Callsign, Name RST etc can be easily transferred 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.
If you like to see more information you can take a look at the manual at: http://www.wolphi.com/ham-radio-apps/droidpsk/manual/
The suggested frequencies for PSK on the Amateur Radio bands are:
- 160m 1838.15 MHz
- 80m 3580.15 MHz
- 40m 7035.15 MHz for region 1 and region 3, and 7080.15 MHz for region 2 *
- 30m 10142.15 MHz
- 20m 14070.15 MHz
- 17m 18100.15 MHz
- 15m 21080.15 MHz (although most activity can be found 10 KHz lower)
- 12m 24920.15 MHz
- 10m 28120.15 MHz
If you experience any problems or have any suggestions please let me know at email@example.com. I would like to hear your feedback.
- Calculate passes for up to the next 24 hours
- Graphical pass display
- Map view showing current satellite position and next two orbits
- Update keps from a file on SD card or directly from AMSAT's webpage using your phone's internet connection
- Set home coordinates from User Input (Lat, Lon, Maidenhead), Network or GPS
When she or he will be able to write down on paper at least 90% of the sequence, she or he will add another letter of the Koch sequence. Then the application will run with three letters and so on.
I love using this application on my smartphone because I can exercise at any time and anywhere.
NOTE ON GARBLED AUDIO - Garbled audio has been fixed: starting from Android 4.1, 8-bit audio support has been broken; 16-bit audio still works.

The app is very simple to set up just needing an amateur radio callsign and the APRS passcode for that callsign (available on request from Cross Country Wireless).
Menu options include GPS position information including WGS84 locations for worldwide use and.OSGB locations for UK users. Another menu option also opens an OpenStreetMap based on the GPS fix.
The app can be used on any Android phone or tablet with GPS (and Bluetooth for use with a DigiTracker). If your Android tablet does not have GPS then the app will not work.
Note...the GPS on some Samsung phones doesn't work with this app. As a result the app is now provided free of charge for amateur radio experimentation.
Get notified when propagation is reported to be good for a particular frequency band.
Now with great circle and heat map plotting on Google maps!
